  2. Hi Everyone, I would like to know in detail about the different implementations of data pathways. I currently use windows and I can hear stark difference between music players with different libraries. Most music players with same library sound similar or identical. HQplayer, Winyl and Xmplay sound identical at identical settings while musicbee is similar but slightly sounds lacking in depth. Aimp sounds very different. Foobar sounds very different and lifeless (apparently goes through windows mixers even in asio and has measurable distortion). Albumplayer sounds very different. I can pretty much narrow it down to - if any uninteded processing is happening (like in foobar), or to the way instructions are laid out. The science of getting jitter free data out of CPU is a topic in itself, and I would like to know if there is any kernel/compiler available for linux/bsd that tries to remove the effect of speculative Execution Jitter. From what I know, the current ways are to have tonnes of Lfence instructions or modify the clang so that the instructions are in such a way that spec/ooo execution or other enhancements always returns a predictable sequence (a miss). I have tried a few such programs and while I can hear differences (with the usb dac and supra cable I have), I am not sure if it is all improvements or if there is any skipping going on. I am planning to upgrade my dac. I am thinking of the dddac but haven't setted on one single dac yet. Without a doubt it will be diy and my intention is to use custom coded upsamplers/dithers that I would pre-processes and store before sending the data in 192khz or 176khz, 24 or 32 bit.. I am now confused on the available ways to transmit the information from the processor to the DAC. I will split up the question into two parts. First question I have is, What are the available protocols that communicate data to the dac? I currently use USB, I can see that the data is fetched, packeted, sent to the USB port dma controller. From here it goes to a USB slave which also has a buffer and converts this stream to timed i2s data which will be fed to the dac. Since USB transfer sequence is timed (i think at 125ms between polls) Isosynchronous mode of USB frame skips frames if 44100hz sample rate is used (8000*5 or 6 alternating missing 100 samples). Asynchronous buffers these things so no interpolation in terms of data transfer but doesn't have any error detection or correction and god knows what type of errors/issues could pop in (I hear changes in cables so I don't believe all is well in USB). I went around looking at other protocols - spdif, toslink etc. SPDIF uses manchester encoding and the slave has to decode clock from the data stream. This kind of makes it necessary to have very good engineering in both the master and the slave, and i'm unsure if they will be that much issue free even after that. And the standard looks variable, general certification is only upto 48khz 24 bit though there are implementations that go till 192khz 24 bit. Toslink does the same with optical format (but not the high quality optical standard used in internet transmission and hence apparently varies with cables). I am unsure if any of these support error detection and/or correction. Also all of these seem to have single serial data line. Is there any dual channel data alternative (Ethernet seems to support dual channel, or is it just full duplex they are meaning?). Another interface I saw was aes which is similar to spdif (or is it a subset of spdif?). Ethernet based audio transfer seems to be what is used in the network streamers, with custom protocols on top of the ethernet protocol if I'm right and it seems to be a good way to go about things before sending to the slave. And direct i2s communication over RJ45 or HDMI seems to be available as well but then again i-i communications are a blank slate meant mainly for inter-ic data pathways and I'm unsure how the protocol will hold up to sending over a large line. I would like to get more enlightenment on this topic and subjective experiences of what works best at the moment, the reliable brands of decoders, reclockers, the available chips, diy-options etc. The second question I have is, how is the data taken out from the CPU/memory. For usb, cpu communicates to the USB controller and fills up the data in its buffer before it sends. Another option I've seen common in single board computers is that i2s is available as an i/o from the board itself. As usual, since a general mass production unit may not have good timing (besides they run out of switching power supplies), there are units that take in this i2s stream, buffer, and regenerate them into i2s,spdif or usb signals (like allo kali,digione etc). I have seldom come across chips that communicate to cpu through PCIe and spit out i2s signals (except maybe pinkfaun). Why is it so. What are the other options available for taking data out from cpu with as minimal jitter as possible (provided the software makes sure the cpu is not introducing a lot of jitter). Are there any dedicated computer architectures meant to handle music streaming well enough (ignoring realtime microcontrollers running dos like operating systems). I'm sorry if it sounded too pedantic. I already have a setup I enjoy even out of usb, and I'm only planning to get a better experience. I just want to learn all the options before diving in. And as an EE student, learning these is a lot of fun, and implementing even more so. This is the reason I'm buying diy dac as well and doing my own custom upsampling, just to learn.
  3. Hi, Could anyone help me with or give me pointer where to find info to connect the Amanero module (https://amanero.com) to the DAC board of my AN DAC 2.1x over I2S. I want to exploit the 18/bit192Khz capabilities of the AD1865, connecting my DAC 2.1x (Signature) via USB, bypassing the CS8412 receiver as this only goes to 96Khz. Thanks.
  4. Hi everybodyI discovered that a DSD DAC for raspberry does exist: http://www.terratechnos.com/products/te ... index.htmlIt's not cheap, in fact 25000 yen + 3000 yen shipping from Japan, makes a total of about 220$ https://terra-online.stores.jp/ However, it seems an interesting object, with separate power for raspberry and dac Automatic upsample Works with Rune, Volumio, PiCore Player, Moode.. Instead, I'm not sure how to interpret this spec re master clock:Built-in small crystal oscillator excellent in phase noise characteristics as master clock (45.1584 MHz for 44.1 KHz, 49.152 MHz for 48 KHz) Automatic switching of master clock
  5. Teddy193 - 19V 3.5A 66.5W (12 nanovolt ripple - lowest on the planet!) picoPSU-160-XT, 160w output, DC-DC Power Supply MSI Z370i GAMING PRO CARBON AC mini - ITX PF i2s PCIe expansion card. (PF have verified voltage requirement) I am interested to know if: the setup should be left alone - as is? (i.e. just PICO?) OR is it possible to put a linear regulator on the PATA/MOLEX 12v line for the i2s card? (what device would be required?) is it possible to put a linear regulator on the CPU 12v line for the CPU? (what device would be required?) OR Have a seperate LPSU for the PATA/MOLEX 12v line for the i2s card? Have a seperate LPSU for the CPU 12v line for the CPU? Please refer to picture! Many thanks! PS: I know I need the 4 to 8 pin CPU converter cable B.T.W. (LOL)
  6. I am doing preliminary planning for a dedicated audio computer to replace my modified laptop. My W4S DAC accepts I2S input. From postings here I2S sound quality is at least as good as USB and probably better. Pink Faun and maybe others make an I2S out board. So I am thinking of using I2S and maybe building in a good USB output to make direct comparisons. Anyone have experience using I2S out and into their DAC, comments on SQ, tech issues, etc. Thanks.
  7. Hi, I'm currently utilizing the USB input in a PC>DAC2 (non DSD/SE)>amp setup and with the recent resurgence of the DAC2 DSD and SE upgrade, I'm wondering if there are gains to be made in a few different upgrade options: I've read a few articles favoring the I2S input of the DAC2, so I'm debating between purchasing a USB converter that will utilize said I2S input (either Channel Islands Transient MKII, Audiobyte Hydra X, or others?), or upgrading to the DSD version. I have no interest in nor possess DSD files, but if the upgraded USB input would be equal to the addition of a USB/I2S converter, it would certainly make the decision easier. Does anyone have experience/sage advice in this regard or other recommendations? PS: I am aware of the Empirical Off-Ramp as having an I2S output, but seeing as it costs more than the DAC2, its hard for me to justify the cost. Also, I'm looking for an emotionally involving experience when listening to music, if that means "warm" or "tubey" than that is what I'm looking for. System: PC, Wyred DAC2, currently in-between amps and running a restored Sansui Model 8 Deluxe but considering a Decware TORII MKIII tube amp, and Philharmonic Audio 2 speakers. Thanks in advance for your help!

  9. Hello, Is it possible to run Allo Digione autonomously as i2s to SPDIF converter? I'm wondering if I could feed digione with power supply, I2S_BLCK, I2S_LRCK, and I2S_DOUT taken from separate device and convert it to spdif without involvement of raspberry? Have anyone ever tried that? I'm interested in performing modification of minidsp DDRC-24 described here: https://imgur.com/gallery/kblEy and use my Allo digione as i2s>spdif converter instead of buying a new device.
  10. Hi all, I've recently acquired a very nice vinyl setup and haven't been using my digital gear at all. I'm downsizing to a Hifi-Berry and am selling all my current digital gear. To start with, I am ONLY offering the AudioPC and HDPlex unit as a package deal (but very fairly priced, IMO). See below for specifics. Pic of each component in my room: HDPlex LPSU + HDPlex PC PSU + AudioPC price = $650 plus shipping. US customers only at this point please. Audio PC Specs CPU: Ivy i5 3570K Mainboard: Asrock Z77 Extreme4 RAM: 16 Gb DDR3 System SSD: 128G Music SSD: Samsung EVO 850 500Gb Sound card: Pink Faun RJ45 I2S (optional) Case: Silverstone GD09B PSU: HDPlex 250W DC-DC ATX Installed software: Server 2012R2, fully activated (will provide license key to buyer) Audiophile Optimizer JPlay JRiver MC20 RoonServer (will need to provide new account info) REW I do not intend to format the system drive. I will tape down the HSF (stock intel unit, it's quiet) and remove the HDPlex PSU for shipping, to be shipped in a separate box. The Pink Faun card is extra, and is really only useful for someone with an Aqua DAC. It could be re-pinned by Jord at PF to another maker’s i2S input though, for a reduced cost vs buying a whole new card. This is a $150 addition to the price of the PC + HDPlex combo ($500 retail) Administrator password changed to “administrator” No other accounts are active on the machine. HDPlex main unit is the 300W LPSU unit driving the 12V side of the PF card and the 19V input of the ATX 250W DC-DC supply in the PC. This setup is dead quiet, electrically and sonically and produces a very open, airy, and neutral sound. It pairs incredibly well with the DAC I'm selling (I would consider a combo deal for all of it to the same buyer). Aqua La Voce S2 DAC with factory XLR upgrade - $2150 shipped to anyone in the lower 48. International shipping available on this, but I will need to get a quote and work with the buyer on fair pricing. This is also listed on Audiogon under my handle "toddrhodes" if you'd like more detail on it. This is a lesser-known DAC but is absolutely worth consideration if you have the budget for it. It's sound is best characterized as "pure." It is faithful to the recording, it is an R2R/Ladder DAC, non-upsampling. It features 4 digital inputs: Galvanically isolated USB 3.0, AES/EBU, SPDIF via 75 ohm BNC and the proprietary Aqua I2S input (to match the sound card I have in my Audio PC). This is a very good digital frontend, make no mistake. My selling is merely a matter of having a current preference for vinyl and all that it entails. Personally, vinyl is a different sound which I prefer, but I would never call it "better" as that is different for all of us. Feel free to PM with any questions. Not taking offers at this point, I feel my prices are extremely fair given the condition and performance of these components. Thank you. Todd
  11. View Classified Singxer SU-1 + Sbooster Ultra I'm selling a Singxer SU-1 DDC in mint condition. It is still one of the best DDC in its price range, especially when used with a good linear power supply. Optionally I can sell an Sbooster Ultra MKI 5V linear power supply and the connection kit for the SU-1. I'm providing original boxes to both the Singxer and the Sbooster. The Singxer is in a rare silver color (you cannot find it / buy it anymore). The price of the SU-1 is 220 USD, additionally the Sbooster would cost 200 USD. Buyer pays shipping and PayPal fees. It is shipping from Europe. Seller robi20064 Date 10/14/20 Price 220.00 USD Category Digital to Digital Converters
