  1. One of the finest CD/SACD players on the market, a favorite of John Atkinson at Stereophile. Reviewers from Stereophile and The Absolute Sound have favored this player since it was released; with the apodizing filter application developed by Ayre (see white paper on ringing) this player finally brought CD/SACD sound to the highest level. The Ayre is truly built like a tank, renowned for its transparency and plays flawlessly. Width and depth of soundstage, extraordinary dynamics, silent as the tomb, slam and dynamic range, you will not EVER need another CD/SACD player in your lifetime. It has been rated a Class A Stereophile product since its release. This unit is in flawless condition, it has no imperfections or blemishes whatsoever. Zero laser performance issues. Panasonic does make a laser transport replacement that can be swapped out should this one eventually wear out. Contact Ayre for details. MP ( minimum phase ) and the transformer isolation upgrades - were completed 4th quarter, 2019. This unit provides up to 8x oversampling. AES digital output Balanced XLR and Unbalanced RCA output. Format: red book CD, SACD, DVD-Audio, DVD 120V power supply. If power supply is compatible to your region, I will ship internationally.
  2. Over the years I have become very familiar with the Waversa product line and have auditioned or owned most of their equipment at one time. Their approach to digital audio in unique and I have enjoyed watching this technology evolve. One challenge I enjoy is tying quality with affordability and Waversa may have done just this with their new sub-$5000 DAC, the DAC3c (compact). The article below was originally written in Japanese and pulled from the Waversa dealer for most of Asia. www.waversasystems.com. To my understanding, this is a private dealer representing Waversa, which is based in South Korea. With the help of Google translate and further editing including my experience with this dac and their product line, I am re-publishing this summary. If anyone knows of another DAC manufacturer with a similar approach or their own unique approach, I would be very interested in learning about them.A different approach to digital processing unique to Waversa and why:Generally, upsampling uses an FIR filter (Finite Impulse Response, fixed-form impulse response filter). Interpolation (interpolation) is performed during the upsampling process to correct the sound quality. FIR Interpolation is a mathematical calculation that estimates and fills between digital points.In the case of the Saber ES90x8 series, such FIR filters are basically built-in, and DAC manufacturers can easily perform upsampling. However, in the case of incorrectly made upsampling, the sound becomes thinner, and it is often proved that listening with the upsampling function turned off sounds better.WaversaSystems uses a proprietary WAP instead of the basic FIR filter included in the DA chip. Waversa Audio Processor (WAP) is designed inhouse with a multi-stage structure including a number of proprietary FIR filters and IIR filters (Infinite Impulse Response Filter) and performs high-resolution upsampling. This high-resolution upsampled signal is processed through thousands of iterative calculations using state-of-the-art source estimation algorithms to reduce digital errors and create a waveform that is as identical as possible to the original analog signal. This is the role of WAP.WAP (Waversa Audio Processor) Hardware method with very low jitter rate and accurate timing Proprietary solution from digital input to processor Dual WAP captures all signals on the optimized route Centralized clock management in the signal path Technology to minimize Quantization Error Processes huge information up to 32Bit 1.5MHz Highest level signal restoration algorithm by applying medical technology Very few DAC manufacturers have developed their own digital processors because the development of digital processors requires significant understanding and knowledge of digital signal systems and is difficult to develop alone, and most DAC manufacturers use DSPs built into the DAC chip or use off-the-shelf modules. However, some high-end DAC manufacturers, such as CHORD, DCS, and MSB, design digital processors independently with sound quality as the top priority.The software processing method has elements that cause errors because the processing is sequential and complicated. On the other hand, in the hardware processing method, since signal processing is performed once at the same time, there is no room for jitter, and the timing of the audio signal is exactly the same.WaversaSystems digital processors are processed in hardware, not software-based digital processing, so they are processed simultaneously in a simple, optimized path resulting in fewer errors, and the timing of the audio signal is handled more accurately.Modular design vs. proprietary signal path system:Most DAC manufacturers produce modularized DAC components individually arranged and combined allowing for ease of development and production with easy with off-the-shelf chips. As a result, only a few DAC manufacturers have their own signal systems, and DACs of those brands are priced at more than $10,000. WDAC3C is a signal path system specification originally developed by WaversaSystems. All signal processing has been optimized, including a proprietary USB input circuit, network renderer, digital processor and DAC, and is controlled and operated precisely by a clock system unified by a digital processor (WAP). This method has a lower error probability, higher stability, and ideal digital signal processing than the method of circuit design using commercially available modules.Dual WAP captures all signals In order to dramatically increase processing speed and efficiently manage signal processing. The first WAP (P1) processes all input signals, and the second WAP (P2) receives signals processed by P1 on I2S and decodes signals with clocks according to sampling rates. In this way, by assigning a unique role to each digital processor, signal interference is minimized, more sophisticated clock management is performed, and sound quality benefits from accurate signals that do not compromise digital signal integrity. The heart of WAP lies in signal restoration. 32Bit 1.5 MHz, processing huge informationThe WDAC3C does not use the FIR built into the general ES9038, but uses multiple stages of FIR with proprietary logic to perform high-resolution upsampling. Instead, the heart of the technology is included in WAP, and the newly developed WAP has greatly increased the amount of data that can be processed. This new WAP has succeeded its predecessor (24Bit / 368kHz) with 32Bit 1.5MHz data processing. In comparison,16Bit, 65,532 digital signal processes are performed, and in 32Bit, there are 4 billion digital signal processes, and the sophistication of signal processing is dramatically increased. This has made it possible to generate digital signals that are closer to analog, and the subsequent digital restoration technology has become more accurate. To put it simply, the improved internal processing speed of 32Bit 1.5MHz is similar to upgrading from DVD quality to 4K quality. This dramatically increases the detail and dynamic range that can be expressed.WAP sounds more natural as you step up WAP's signal restoration algorithm technology increases in sophistication as the numerical value of the calculation accuracy increases. This is managed by WAP Level. WDAC1 has one stage of WAP, WDAC2 has three stages, WDAC3 has five stages, and WDAC3C has nine stages. This WAP is a computation that is processed at the digital stage and can be upgraded by connecting devices.WCORE and WRouter are WAP level 3, yet when connected to WDAC3C with WAP level 9, a synergistic effect results and the WAP level is measured at 15. The higher the WAP level, the more sophisticated the processing per unit time, and the better the sound image and detail. And the tone of the instruments is also flexible, natural and easy to hear.In designing and developing a DAC, there are several components that affect sound quality. Several factors, such as the design of the input / output lines, the design of the internal algorithm of the digital processing chip, and the performance of the DA chip, the design of the power supply unit and the design of the analog output unit are directly related to the completeness of the DAC.ES9038PRO is a flagship model consisting of 8 channels that features 32-bit processing and ESS patented 32-bit HyperStream DAC technology. The HyperStream architecture has excellent sound quality and very low intermodulation distortion characteristics and has superior audio characteristics compared to general competitors using the delta-sigma architecture.Digital processing of WDAC3C: The performance of the DAC chip is also very important for the DAC, but it is not the only one. If DA chip performance is important, all DACs with the same DA chip should sound the same. The choice of a DAC chip is important, but the consequences will depend entirely on how the DAC chip is used. The WDAC3C uses only the most basic functions by bypassing the ES9038PRO and achieves excellent sound quality through original and unique designs for both the input and output sections. Two of them are WAP and WMLET.WDAC3C has introduced two unique technologies from WaversaSystems to make optimal use of the ES9038PRO with a 32-bit 8-channel DAC.One is WAP, a source estimation algorithm that operates at 32Bit 1.5MHz. The other is Range Separation Technology (WMLET). Channel separation technology for sound range and (WMLET – Waversa Multi-Layer Energy Transfer)Rather than using the commercially available ES9038PRO chip as it is, WDAC3C has an algorithm that passes the circuits of the input stage and the oversampling filter stage and instead uses the WAP chip to process each process individually. It is then passed on to the ES9038PRO by another key technology, the range channel separation technology (WMLET). Range channel separation technology (WMLET-Waversa Multi-Layer Energy Transfer)As the name implies, the auditory frequency band is divided into high, mid-high, mid-low, and low bands at the digital stage for each of the left and right channels, and passed through eight channels of ES9038Pro for processing. In conventional signal processing, the energy is concentrated in the middle band due to the characteristics of the analog element. Instead of 8 channels, only the left and right channels will be processed together, and more energy will be concentrated in the mid-band. To prevent this, WDAC3C distributes the energy evenly for each band and improves the sound quality. The advantage of separating the channels for each range using WMLET is that the WDAC3C has an ingenious technology that regulates energy in four channels per frequency band, thus improving distortion caused by energy bias and reviving subtle musical elements, a band balance that cannot be felt with conventional DACs has been realized. This approach to digital processing is unique only to Waversa products. The energy concentrated in the mid band is evenly distributed, and the band balance is excellent. The resolution increases with each band, taking advantage of the nuances of band separation and natural music. Implementation of a wider music signal dynamic range and broadband frequency reproduction. Natural balance of the sound can be maintained, and the originality of the tone is maintained. WaversaSystems original network renderer board:Due to the characteristics of network players that use computer networks, DACs are exposed to a large number of high-frequency noises that were not found in conventional CD transport and analog devices, and are adversely affected by sound quality. To minimize these noises, WaversaSystems has developed and produced its own network renderer board. The reason why the renderer board is important in network players is that the network renderer board, which is the entrance of the signal, generates a lot of noise inflow and is not designed for high-end sound quality. WaversaSystems network renderer boards are also designed to apply noise filters to LAN or USB ports, operate at high speeds instantaneously and limit the processing speed to minimize generated noise. Renderer module installed by high-end manufacturer CReceiving, restoring, and playing back network data signals requires high quality and accurate digital design techniques. A technology that filters various noises that exist simultaneously with music signals on the network and is transmitted in the same way, and a technology that protects minute data contained in the sound source signal and has a huge number of elements that combine network, digital, and analog Power must be designed and manufactured with a high degree of perfection in a well-balanced manner. WaversaSystems Network Renderer board: Noise-free design (cut off external noise, minimize own noise generation) Optimized path, excellent stability and sound quality benefits Easy setting with Web browser Updates and upgrades to improve sound quality and stability System check by remote support is possible Dedicated protocol can improve sound quality and add various functions WDAC3C's renderer board supports various network protocols (DLNA, RAAT, Airplay, WNDR), and plays an important role in transmitting sound source data without loss so that WaversaSystems' signal transmission processor WAP can achieve the best sound quality. The unique design minimizes bottlenecks and conversion steps, and the optimized path provides stability and sound quality benefits. WNDR (WaversaSystems dedicated protocol) Transmission scheme optimized for continuous signal processing without buffering Protocol with strong immunity to noise Protocol without conversion process by dedicated route Increased WAP level due to interconnection (improved sound quality) WNDR is a protocol originally developed by WaversaSystems. The network renderer mentioned above is a hardware advantage of WDAC3C for network audio, and WNDR is a software-like superior sound quality advantage. WNDR is a protocol dedicated to the transfer of pure music with little buffering and has the special advantage that there is almost no noise during signal transmission and no sound quality distortion occurs.The biggest problem with streaming widely used networks using DLNA is that the standard does not consider continuous audio streaming at all, it is just a standard for packet-based data transmission. In this transmission method, noise is generated during the buffering process during signal transmission resulting in extremely poor sound quality. WNDR is a proprietary protocol developed by WaversaSystems to solve these problems. It has been developed to minimize delays in communication and provide excellent noise immunity. In addition, the WNDR method is a dedicated protocol, so there is no need for a conversion process between protocols, and sound quality can be improved. In addition, WNDR is a more advanced protocol than other protocols and is more immune to noise.Noise generation by network transmission methodThere is also a dispute over how noise is generated in network protocols. On a common shared network, data is not transmitted in a dedicated (exclusive) manner, so it uses a method of moving on a shared network in packet units and buffering the data in packet units. Noise is induced in the process of reading this buffered data. When reading buffered data as shown in the figure, the process of reading and transmitting data with a renderer board or the like occurs intermittently, which causes electrical noise. The stable transfer of continuous information without buffering will be the core technology of the future, and since media integration tends to be parallel to communication, stable clock synchronization without buffering will be achieved. The technology that does this is WNDR, which is a great sound quality advantage. You can tell if there is buffering by unplugging the network cable.In the case of DLNA, music is played continuously for 30 seconds or more, and in the case of ROON RAAT, music is played for several seconds. This means that the buffered music data is being played. However, in the case of WNDR, the music is interrupted almost immediately when the network cable is unplugged. This is because there is no buffering. WNDR, which operates with WaversaSystems DAC, is the only product in the world that operates with a proprietary music data transfer protocol. WNDR produces a synergistic effect when all devices are integrated, and combines with WAP to achieve even better sound quality. When WCORE, WRouter, and WDAC3C are all connected by WNDR as shown in the figure, they will have clear sound quality benefits. In addition to that, it has been raised to the WAP level, achieving higher-end sound quality with higher dimensions.This dac is the newest of their product line and the culmination of years of innovation where the trickle-down theory actually outperforms the rest. My impression: the DAC3c performs better than its big brother and on par with their current flagship dac, if not better.

  6. Up for sale is my Empirical Audio Overdrive Diamond SX - Low hours use. I live close to the builder/designer Steve Nugent. This unit is in immaculate condition as are the internal boards. Everything is current with most updated boards and updates. I am upgrading to the TotalDac 12 system. The Ethernet input is one aspect that sets this unit apart. No need for a server. Empirical Audio never goes on sale and Diamond SX rarely is seen for sale used on the market, especially one in this mint condition. $6900 plus shipping. Retail is $13000. Although I prefer Ethernet direct to I2S "Interchange" unit. This can be switched to a new XMOS properly galvanically isolated USB module. A new design USB board is available: "First new fab USB module PCB is back for the Off-Ramp 6. Built one by hand and it worked first-time. Complicated board because it's galvanically isolated (the right way). " I have seen this new board first hand and it is the best design on the market. To successfully galvanically isolate without introducing new jitter. There are advantages both ways. If USB is your preference, we can discuss a swap out. See Empirical Audio Interchange - The Interchange is built into this dac but has the advantage of direct I2S conversion with shortest signal path possbile: http://www.empiricalaudio.com/products/short-block **This dac is also in Steve's possession to be the first to receive the new oscillator upgrades for the turbo clock module!

The Overdrive has extremely low noise and overall coloration.”Steven Plaskin, Feb. 2018“If I were to sum up the Overdrive SE's sonic qualities in just a few words, those words would be clean, accurate, precise and fast. By comparison to the Overdrive SE, most of the other DACs I've auditioned sound veiled and slow... The Overdrive is incredibly resolving, and its detail is a result of exceptional clarity..It is outstanding in every way, outperforms many more expensive DACs and I unequivocally give it my highest recommendation.”Laurence Borden, Dagogo, Jan. 2015“…my independent impressions of the Overdrive DAC were confirmed when I made direct comparisons to other highly-regarded DACs. The Overdrive emerged as my preferred DAC.”Ed Momkus, Dagogo, Mar. 2011“…regardless of how I employed the Overdrive DAC I was aware that I was listening to the best USB DAC I had ever reviewed.”Steven Stone, The Absolute Sound, Feb. 2010Award Tas Golden Ear 2010 SmallThe Overdrive DAC received The Absolute Sound ‘Golden Ear’ Award 2010-----Overdrive® SX USB DAC/Pre:A World-Class Digital to Analog Converter with volume control and either USB or Ethernet interface, as well as other interfacesThe Overdrive SX DAC is a breakthrough audio product, our third generation of this DAC. Our original Overdrive and the follow-on Overdrive SE won awards and accolades, but the sound quality of the SX is in another league. If you want the music experience that moves your soul, the Overdrive SX can deliver this. It is detailed without being harsh, dynamic from top to bottom, quiet enough to deliver the blackest backgrounds and precise enough to deliver the deepest, widest and most focused image you have ever experienced. Very 3-D presentation, provided your room setup is optimum. You will easily hear the difference between different formats, like FLAC, ALAC and .wav. Even 44.1 PCM tracks will sound like hi-res DSD or MQA. It actually makes these hi-res formats unnecessary. The Overdrive SX does not support DSD.It is available with our excellent low-jitter 192 asynchronous XMOS-based isolated USB interface or our excellent low-jitter 192 Ethernet Renderer interface (DLNA/UPnP) built-in. Either of these deliver data to the D/A with 10psec of jitter (jitter plots below). In addition to one of these two interfaces, the Overdrive also has S/PDIF coax input on BNC connector and single-ended I2S input on RJ-45 connector. The Overdrive SX has balanced and single-ended outputs, but the single-ended RCA outputs should primarily be used for a subwoofer. The Overdrive is best used with balanced outputs. If your equipment does not accept balanced signals, we can provide our Final Drives to change from balanced to single-ended. Even though the Overdrive SX is a Sigma-Delta modulator architecture, it delivers the live sound quality of NOS and R2R tube DACs, without having the tubes to wear-out. It is more accurate and more dynamic than any R2R DAC we have heard.Because of the excellent volume control technology, the Overdrive SX DAC enables you to play music from your computer directly to your amp, achieving unparalleled sound quality. All you need is the Overdrive and a PC or a Mac, an amplifier and speakers and you are ready for music. The Overdrive will also improve the playback from your CD transport or other devices like Sonos, but we recommend using our Synchro-Mesh re-clocker to reduce jitter from those first. Once you start using the computer for music, you will never go back to spinning CDs. Playback using the computer will be superior to the best CD transport you have heard, even when playing low-res CD rips, provided you use optimum playback software and quality cabling. Once you have an Overdrive, we can assist you with the ancillary things needed to achieve optimum performance, like cables, software, re-clockers, isolators etc..The Overdrive design philosophy is minimalist, with one of the simplest analog paths ever devised. The Overdrive provides innovative solutions for the five most important issues with digital sources:-----"Greetings Everyone.I wanted to update you regarding Steve Nugent's Empirical Overdrive Diamond SX with the optional internal galvanic isolated Ethernet direct I2S converter cpu. I have run the unit 24/7 for over 1000 hours and I must admit the caps needed this time to break in. This will be the first dac that I felt needed over 6 weeks of almost continuous play to break in. However, this is one instance where patience paid dividends.Since we all have our own perception and certainly favor different qualities, I am not going to delve into a lengthy review. The qualities that stand out and I believe most would agree, the dac is well balanced on all fronts and certainly demonstrates design implementation is more important than the dac chip itself. Historically, I have been approached by others who felt the ODSE was overly analytical. I humbly disagreed as I found it to be detailed, accurate and perhaps unforgiving. While I found the SE emotionally engaging, the SX is addictive. The more dacs I audition, I find myself with a preference to non-oversampling design implementation. My goal is to compare this unit to a R2R ladder dac, Totaldac, and will report my results. At 4x the price, it would have to engage me on an entirely different level. Steve's dac chip is proprietary and I feel discussing design theory should be left to the electrical engineers.At first blush, I had found little difference between the ODSE and the ODSX. Over time the Diamond SX bloomed, creating an even more precise presentation of the music. Well-recorded intimate recordings immersed me into a room of musicians. Big venue live recordings placed me back from the stage, closer to the soundboard, creating a deep and viable soundstage. Both the ODSE and the ODSX have been the best interpolating PCM data and recreating an accurate presentation of the recording, especially piano, wind instruments, and particularly the mid and upper range of percussion decay. I still hold to my initial assessment years ago. I have yet to find a DSD dac that performs better than Steve’s implementation of PCM. However, I have not heard a ground up designed DSD only (non PCM) dac.The chassis is no different that the ODSE. The faceplate now states SX in place of SE and the knob has a very subtle recessed diamond. Nice touch but for those who upgrade their SE to SX, I would keep your old faceplate and save money. The rear panel is the same. Mine had a manual cutout where the Ethernet input replaced the USB. This does bring me to another point: For those of you who will upgrade, the ODSE/X run hot. The morphology of the circuit boards change and this will affect the soldering. I highly recommend you pay the extra nominal fee and use a virgin board. Longevity is essential. While I am sure Steve will service these units well into retirement, save yourself the headache.Those of us who owned these units before know these units run hot. While breaking in, I ran the unit in my office on my desk, which is quartz composite. The unit ran hot, up to 208* over the Ethernet board. Steve assured me this is not an issue. When I placed in my system on Bubinga wood, the temperature dropped by 50* while being relocated in direct sunlight and reset to high-output line out. Surfaces matter, ventilation matters. I have run this dac hard without failures on any level.The Ethernet DNLA/UPnP is simpler, more robust, and strait forward. Unlike USB, Ethernet packets of data are checked for errors and packets with errors are resent. The more I read about USB implementation, more validating why I despised it and found it universally inferior to AES/EBU. ROON uses its own RAAT protocol in place of DNLA/UPnP. The third party company which designed the Ethernet to I2S converter CPU chip has no interest in RAAT. ROON states they will implement DNLA but with no timeline. Because of this current incompatibility, I have not pursued ROON at this juncture. One manufacture who uses this CPU has figured a work around and was able to implement ROON RAAT. However this was not to an I2S conversion. Through Bubble UPnP and Linn Kazoo (both free) I am able to stream Tidal without any issue. Linn Kazoo is not on the same league as ROON or even Tidal’s own controller. To say it plainly, the user interface sucks.There are many third party controllers. Some are free, while some are cheap to purchase. They all work well, and I give credit to this third party manufacturer. Not all Ethernet dacs/Renderers have this level of performance. Please note: I find those controllers that send a file direct from NAS to the DAC without processing sound better. Those who have interest in this topic please PM me for more detail and discussion. I would love to learn where others have found success and discovered absolute ‘do not’s’.I wish to commend Steve on a well designed dac. Thank you for reigniting my passion for this hobby. This last year has been somewhat frustrating for me. High-end components do not necessarily play well together and this certainly has been a journey. When my wife leaves a concert and says that sounded as good as listening at home, she is complementing the venue…and Steve the credit belongs to you."
  7. Paul Hynes/Steve Nugent design. I bought this to run my Empirical Audio Dac by Wi-Fi to Ethernet converter. I never used it once. This is a new item. Empirical only sells these units when tied to another Empirical electronic with Ethernet input. They never go on sale used and are never on sale.LPS can handle up to 4 A but has 3 A fuse.Upper USB port is signal in and lower USB port with cable is signal out.My price is firm.$1000 new, $800 Plus Shipping, PayPal or bank transfer.
  8. I moved away from home built server since commercial servers are evolving and becoming easy to use and retain great sonic qualities. The power supply for this unit created noise in my system so I tossed it. Any good power supply would work great. I decided not to replace it since the new owner would wish to use their preferred power supply. This unit has many goodies and evolved into 3-4K in hardware and software. Some are listed below.... audiophile optimizer windows server 2012 r2 paul pang red cable 80 gb SLC SSD jcat usb card
  9. I have two of these Glass Toslink cables. I no longer need them $85 new. $35. No issues. Change in gear setup made these redundant. Two cables are available - $35 each. Shipping. $8.
  10. Another review with favorable review from these unknown cable: http://www.theaudiobeat.com/equipment/allnic_audio_int_sc.htm Having first hand look at various manufacturers from Korea. I like what is being offered these days. Highly recommended.
  11. Greetings,To any current owner who has a pre - late 2017 D5000, I have a new output board and tubes that would improve sonics and lengthen tube life.I have one set and will ship. There is no fee. Allnic contacted me and I had sold the dac but the new owner never replied. I would like to see this board go to good use.John.
