  1. Hi! We are delight to have return customers to upgrade for Emperor Signature. The music is just so smooth with Giesemann Clock, we hopes good music keep goes on everyday. 🙂
  2. The story of development AfterDark. is looking for better solution, when we modified and design the new product line. Since we become Sponsored in Audiophilestyle.com, we meeting a lot of old friends where they shares their way to improve sounding with the highly modified network switch. We remember I have a night to visit Hols's place in Hong Kong, when we are dealer for Denafrips R2R DAC. @Hols is a well known audiophile in Hong Kong. Therefore, after reading the below sharing, he is using Buffalo BS-GS2016 in Cascade connected with SFP Optical Fiber cable. So, we tried to build one with heavy modified - AfterDark. Project ClayX Giesemann OCXO Black Modernize Edition Purchase Link His impression on Buffalo BS-GS2016 Cascade OCXO. "I would prefer the 2016 than the S100 because of its richer presentations. Using one 2016 already gives you the same character but using two is definitely a revelation. Everything just seems to be present around you. The presence is much better with two 2016." by Hols "There is an easiness in the sound and everything come up so sure so accurate and fluent. There is no hint of any slowness or muffled sound or harshness that are sometimes associated with over-cleansing. And can I take out the SOtM? Yes I can and still live very happily with the sound. There is only very slight diminished high frequency only noticeable on critical listening." "Overall very impressed with the clock-modded 2016." by Hols How we design a Project ClayX Buffalo GS-BS2016 SE Edition? Improve the outlook which make it more like a audiophile gear We love the ideas of 10M Master Clock Input function of Buffalo GS-BS2016 The device should be powered externally with audiophile grade LPS The power section should be enhanced with more exotic audio capacitors The Giesemann 10M Intput Modules (GIM) will perform synthesizers 25Mhz independently. this clock signal will be optimised to Buffalo GS-BS2016 The units will be powered by LPS externally. All modules should be fit into one single box The internal wire with optimised with Duelund Silver Cable, and solder with Audio Note The Top Plate of Chassis will be using Carbon Fiber, tailor made for Buffalo GS-BS2016. All the Lan ports inside will be apply with KEMET Corp. EMI Shielding material for eliminate of EMI The use of SFP Single Mode Optical Fiber will give you another isolation to connect Cascade of Buffalo GS-BS2016 Optional 10M OXCO can be build in for customer, who prefer all in one package inside the chassis This MIFLEX Audio Capacitor we used is over sized at 44mm x 50mm and placed on DC power section. It take quite a long time to burn in. After run-in for 7 days, the soundstage open up and so much airly, the sounding is just more relax and rich representation when we compared with other switch. The KEMET Aluminium Capacitor is another big plus to improve the micro details and darkness. Miflex KPCU-01 Copper Foil Paper / Polypropylene in Oil "Check out the new Miflex caps, the copper version are amazing. I've been replacing all of the coupling and/or output caps in all my amps from the Jupiter copper to the Miflex caps. IME the Miflex have better tonal density, more punch, more detail and present a blacker background. In almost every respect that I care about, the Miflex are a serious step up. " Why Buffalo GS-BS2016 needs OCXO optimised? We have same impression with member @Cool_Chris, the OCXO brings a very good sounding Buffalo GS-BS2016 to other levels. "This clock simply adds something that is unreachable in normal switches. It is so calm, fluid and transparent that nothing compares to that. No wonder Jord is installing this clock in his best designs. In short it is mine best switch too and I can't imagine to listen without it." New Giesemann OCXO Module developed for Buffalo GS-BS2016 The new designed of Giesemann Clock OCXO 10Mhz Clock Modules can synthesizers any frequency from 1-100Mhz. For example, two Buffalo motherboard required to receive two 25Mhz from a Giesemann 10M Master Clock. The latest development version of Giesemann OCXO Modules shall accept external 10M Signal, and provide flexible upgrades vs performance. The story behind the new version of Buffalo BS-GS2016 x Giesemann 10M Input Module Black Modernize Edition We received some special requirement from France recently and looking for upgrade option on his switch. He is currently owned a Mutec SE120, 10M Master clock with multiple outputs of 10M signals. So, he would like to utlities his investment and looking for audiophile grade switch with 10M Master Clock in. He knows that Buffalo BS-GS2016 will be his first choices, but he just want a extra modification with 10M Master Clock Input Module. Would it be possible? he asked. Customer: Would it be possible just to modify and add a 10M Master Clock function? he asked. Adrian : Since you want to keep your existing 10M Master Clock to work with Buffalo BS-GS2016, we can look in to it. Customer: If possible, please make a external 12V DC port, so I can use the LPS, it will be great. Adrian : This can be done, we can modify with some Audio Grade Capacitor to be place inside the original chassis, let us found the biggest possible capacitor from MIFLEX Poland. where it can placed inside the Bufallo GS-BS2016. Customer: Let's give me some update when it is ready. Thanks. Adrian : That would be great to have this product, since we have done this projects with Giesemann Clock Modules, we shall design the 10M Master Clock Input Modules from scretch, using the best component and make sure it is small enough to be placed in same chassis. AfterDark. Development ideas: We have some ideas of the new board, a clock synethesis modules turns external 10M OCXO Clock signal into two 25Mhz Clock signal for one Buffalo or dual Buffalos, we shall make two outputs of 25Mhz, just to make sure it is future proof and provide more flexible to upgrades later on. The DC power module requires to be redesigned for new clock synethesis The placement of module will be re-designed and to be placed near the main board, The chassis require to modify and place extra DC port and BNC socket and accept external 10M Input A minististic design, which optimised peformance with choices of Giesemann OCXO 10Mhz Reference Master Clock and Giesemann LPS. There will be a EVO version, which is build in OCXO inside the Buffalo GS-BS2016 for some customers who needs all in one box solution. For customer who likes Cascade of Buffalo GS-BS2016, there will be "Made To Order" SE version which accepting external 10M Reference Master Clock, This version will be using the carbon fiber chassis and re-designed with the new the carbon fiber input blackplate. Customer review and Software tuning with Cascade of Buffalo BS-GS2016? https://audiophilestyle.com/forums/topic/62283-the-development-of-buffalo-bs-gs2016-sfp-10g-cascade-x-giesemann-ocxo-black-modernize-edition/?tab=comments#comment-1159737 https://www.open-end-music.com/forum/händlerforen/grigg-audio-solutions/high-performance-audio-pc/615789-afterdark-switch-2-x-buffalo-bs-gs2016-mit-giesemann-ocxo-in-der-praxis#post619816 "The Buffalo GS-BS2016 will be able to enhance music with more organic and realistic textures, much wider soundstage and revolving dynamics with quality of bass, the details of the entire range will be further improve with AfterDark. Giesemann 10M Input Modules" Why Buffalo BS-GS2016? What is so special about this switch? We are selling DELA S100 Switch and modified version. Just looking at the two motherboard, DELA S100 is using the same motherboard as Buffalo BS-GS2016. This make us quite curiosity on how to improve Buffalo BS-GS2016. So, we purchase two unit from Japan market and see how Buffalo BS-GS2016 compared with DELA S100 (Estimate Price USD1600). So, let us open the metal box and have a look. The clock is placed near the Broadcom CPU. The Giesemann Clock Input Module will be bypass the old clock with external Reference Clock 10M. We love the industrial design of the Buffalo GS-BS2016, it has oversize heatsink and designed to work 24x7. The 1st development of Buffalo BS-GS2016 x 10M Master Clock Input Module Black Modernize Edition The Buffalo GS-BS2016 x Giesemann Clock can be powered by AfterDark. Black Modernize LPS x Giesemann OCXO 10M Edition The AfterDark. Project ClayX Giesemann OCXO 10Mhz Reference Clock (Audiophilestyle.com Edition) The Dual SFP Combo ports will provide more flexiblity for devices having SFP modules. The outlook at the back, minimist designed Adds on OCXO Features The product uses the selected audio grade SC cut OCXO, and through long-term calibration to select and install equipment with excellent stability. Ultra High Quality SC Cut OCXO, very low phase noise and frequency stability SC Cut refers to stress compensated (SC) cut crystal resonators, which is more advance on performance of Frequency Vs Temperature changes, longer Crystal Aging.

Therefore, the phase noise is much better when compared with Paul Faun modules requires the power fitting from motherboard, which creates create interference with power noises.
  3. We have some official reviews form Audiophiles in USA. 😀 http://v2.stereotimes.com/post/network-project: the-anatomy-of-a-network-system-by-moreno-mitchelll/
  4. Hi! Mouna, The warranty is transferable to new owner, Please kindly keep the invoice number of last purchase order, we can check them at the online system. Thanks and have a nice day. Best Regards, Adrian AfterDark.
  5. AfterDark. is always looking for innovative solution, to enhance listening pressure with streaming music. This year, we heard there is some positive feedback coming from a Audiophile from France. He wrote a compensive user guide for using the Diretta devices for streaming music from Roon. The new network protocol called Diretta becomes very interesting for us. We know that the very first product from SPEC -RMP-UB1, is really good sounding and it was recommended by Pachanko Labs. We tried some of their grounding cables, which really makes a huge improvement on fixing our grounding problems on network switches, network players. So, we start to investigate the theory behind Diretta which was founded and headquartered in Japan. First of all, we was thinking that this ASIO Protocol is like the Merging DAC, which use their special ASIO to transfer music via Network called AES67. However, we was wrong, it is not the same technolgies. Diretta ASIO using the another amart approach which like no others in the market. Few months ago, we started the Project ClayX with Diretta. The development kit is tailor made to us with three different versions. The Flagship Model called Diretta Lucia in RJ45 & SFP versions The Newest Model called Diretta Lucia - Piccolo The Raspberry Pi Edition of Diretta in USB Development Kit for Diretta Lucia - Piccolo Development Kit for Flagship Diretta Lucia , SFP SE Edition Development Kit of Flagship Diretta Lucia x QUAD Ruby MICA Capacitors Diretta Lucia x Finisar SFP+ Optimised x Dual Ruby MICA Capacitors Diretta Target Bridge for Raspberry Pi x64 Diretta Piccolo Development Kit on Testing Why most electric noise is hard to filter at the network? Most of the switch can reduce the power- supply noise generated by DC-DC conversions. Using some Audio Capacitor near the DC sources, can reduct the noises. Some circuit designer may apply some low-pass filters and reduct splike like digital-specific noises. However, we it will harm the sound, it is because the filter may filter out some missing information, that is not actually a noise at all, for example, the white noise, which have some extra information to the background, which make music more organic. This may make music digital and harsh as a result of too much filters. It is absolutely difficult to electrically eliminate the noises. Diretta is going to solve this problems in 2 steps... An intergrated Diretta Device with DDC + Diretta ASIO protocol network optimization Diretta ASIO optimised and reduce network noises? Averaging the network processing, moderated the power consumption and current. Use of Target and Host Server concept to reduce network traffic The Host (Roon Music Server) sync the Target device, with more packets at short time intervals, to average out the peak traffic, the transmission is controlled by setting the Target buffer. i.e less electric use, with less noise during transfer The preset profile amd ASIO Buffer can be use to fine tune the sounding. We perform testing on Cascade of Buffalo BS-GS2016, the result is just amazing.

  6. The development of DELA S100 Network Hubs x Giesemann OCXO Black Modernize Edition With the development of D100, DELA developed Audioohile Network Hubs. It fully meets the requirements to ensure the quality of Network Streaming. It takes the function of the DELA series to a new level. For example, using SFP as a high-end network switch, supporting optical fiber technology to transmit signals. Purchase Link The chassis of DELA S100 adopts a sandwich type shock-absorbing structure, and the top and bottom plates are reinforced with aluminum plates to improve stability. And built-in high-quality clock circuit, so that the time base error is further reduced. The power supply part adopts large-capacity capacitor technology to ensure stable and pure voltage. All made in Japan. How we design a modified DELA S100? Improve the outlook which make it more like a audiophile gear The device should be powered externally with audiophile grade LPS The power section should be enhanced with more exotic audio capacitors The Giesemann OCXO 25Mhz will be optimised to DELA S100. The Giesemann Clock will be in module, to supply the cleanest clock signal to the board. The OCXO version should be fit into one single box for DELA S100 The internal wire with optimised with Duelund Silver Cable, and solder with Audio Note The chassis will be using Carbon Fiber to tailor made to place at the top of DELA S100. The use of SFP Single Mode Optical Fiber will give you another isolation to connect Cascade of DELA S100 The EMI shielding from KAMET corp. will apply to the RJ45 ports Enhancement on Industrial Grade Thermal material from Shin-Etsu (Made in Japan) will apply to CPU again. DELA S100 Black SE Edition Black Modernize Full Upgrade: Audio Capacitor upgrade to Frolyt (Used by Goldmund) (Made in Germany) Replace the DC cable inside with Duelund Audio Cables. AfterDark. Carbon Fiber AudiophileMAT Shielding 3M EMI Shielding apply on each Lan Ports / CPU / RAM AfterDark. Project ClayX Giesemann Linear Power Supply at 12V (External) Upgrade Capacitor to Audio Grade Bioplar FROLYT Capacitor (Made in Germany) for optimal sounding (Goldmund used this special capacitor for sound tuning on Preamplifier and their Phono amplififier) Why mixture of Exotic FROLYT Audio Capacitor? Frolyt ERY Series 4700uF x 3 = Total 14100uF Frolyt Bioplar EKSU Series 470uF x 2 = Total 940uF Compared to orignal, Mix of Flolyt will improve the micro details and dynamic of music, more natural and laid back To usd of exceesive and oversize of Audio Capacitor will remove the bottleneck and imcrease smoothess of music flows Why do we choose managed Network Hubs? Customerisation on VLAN, Subnet, Flow Control and QoS can lower the latancy on each lan ports. The sounding can be configured and optimised to Audiophiles. The internal cable is replaced with Dueland Audio Cable. As you see their is extra Capacitor section compared with the Buffalo GS-BS2016. We replaced the Japan capacitor with larger Floyt Audio Capacitor from Germany. The LED light can be switch off by Audiophiles, it can reduce the electric noise and darkness at the background will be increased. We can now confirm the motherboard of DELA S100 is the same as Buffalo GS-BS2016. Someone may noticed that the DELA S100 is only with 8 ports, which is different to Buffalo GS-BS2016 having 16 ports. Actually DELA S100 actually hide the top 8 ports nicely with the back plate and was disabled those port in admin page. The LED can be switch off to eliminate noises. The DELA S100 has external DC port which allow customer to use their Linear Power Supply (LPS) to power them in 12V 1A So we are quite excited to open up the large heat sink and have a look what is inside. The inside is opened, both Buffalo GS-BS2016 and DELA S100 is using BROADCOM BCM53343A, the internal clock is near the silver Broadcom. The excessive size of Aluminium heat sink is good to work 24x7 in commercial. As you may know, the lower the heat, the music representation will be more relax and laid back. The rich representation on sounding and lush airly high may be due to proper sofware implementation and high specification on motherboard, and using a very low jitter re-clock high performance switch with BROADCOM BCM53343A. All internal DC Cables is upgraded to Duelund Audio Cables AfterDark. Project ClayX Carbon Fiber AudiophileMAT Shielding AfterDark. Giesemann OCXO Master Clock Features: The product uses the selected audio grade OCXO, and through long-term calibration to select and install equipment with excellent stability.

  13. Hi Magnuska, Thanks for your message and questions. We found most electronic components working at optimal stage at moderate temperature. That is the reasons and ideas some high end computer runs water-cooling to make music server for HQPlayer. The next project we starting is to build the server which can run HQplayer on water cooling computers. The water cooling can help to transfer heat effectively with the heat radiator. The sounding will be improved too. At high temperature, most devices will sound dull with some high pitch and edges which can easily removed by lowering the heat of chassis. Due to demand on addressing the issue, this may help to solve this problem. Best Regards, Adrian AfterDark. Instagram: afterdark.ig Facebook: https://www.facebook.com/adark.co
