  1. Both Buffalo BS-GS2016/A and Melco S100 seemed to look pretty much the same when we're comparing the PCB inside each unit, unfortunately the clock itself couldn't be seen without removing the heat sink as shown in the second link https://www.hiendy.com/hififorum/forum.php?mod=viewthread&tid=107184 http://my-hiend.com/wp/wp-content/uploads/2020/01/DSC_5221mm.jpg If that heat sink were actually removed, we couldn't really put it back on without messing with the thermal paste and therefore I'd rather stay from that. I'm expecting that both Melco N100 and S100 would share a very similar type of clock from NDK since that should be a good fit under the heat sink of S100, either picture linked below is showing that 24MHz NDK clock for NEC / Renasys µPD720201 where "X17" could be found http://my-hiend.com/wp/wp-content/uploads/2019/04/melco_n100_002.jpg http://my-hiend.com/wp/wp-content/uploads/2019/04/melco_n100_006.jpg I also have D10 and it's the big brother of D100 as shown in the following picture, 24MHz for NEC / Renasys µPD720210 on the left and 30MHz for µPD720231 on the right respectively http://my-hiend.com/wp/wp-content/uploads/2020/01/DSC_5221mm.jpg They might have scratched the surface of the clock and there's no way to identify the model. However, NZ2520SD looked like a potential candidate to me https://www.ndk.com/en/products/search/clock/index.html https://www.ndk.com/en/products/search/clock/1190904_1433.html Nowhere close to the performance of megabuck OCXO products like NDK DuCULoN or even MSB Galaxy, though it's still a pretty darn good deal for such an affordable option https://www.head-fi.org/threads/lks-audio-mh-da003.745032/page-20#post-12775721 https://www.arrow.com/en/products/nz2520sd-25.000000m-nsa3449e/ndk It might be somewhat challenging to put Fidelity Audio C5 inside S100 because of that heat sink mentioned above, it's also requiring its own PSU and therefore I'd rather leave S100 as is. OTOH, HFS1155 from JS PC Audio could be another avenue since it's so easy to replace the clock https://www.whatsbestforum.com/threads/sotm-snh-10g-network-switches-x2-the-new-king-of-usb-network-gadget-setup.27758/page-21#post-625621 Dimensions of C5 are 100mm × 55mm versus 230mm × 180mm for HFS1155, that Connor Winfield accepts either 5V or 3.3V but C5 needs at least 6.5V to operate http://www.conwin.com/datasheets/cx/cx259.pdf https://www.fidelityaudio.co.uk/c5-signature-low-jitter-clock-4461-p.asp Of course there's also this 25MHz clock that costs as much as S100 itself https://www.pinkfaun.com/shop/clock/67-ultra-ocxo.html https://www.pinkfaun.com/shop/sheets/PinkFaunUltra25MHz.pdf However good sounding S100 would seem to be, there's still a lingering question for me. All audiophile switches still have low power CPUs while some supervisor modules from Cisco are much more powerful https://www.cisco.com/c/en/us/products/switches/nexus-7000-series-switches/models-comparison.html Since music servers with Xeon / Core i9 / Ryzen would tend to perform so much matter when compared to similar options with Pentium / Celeron / Atom, just wondering if a network bridge with Asus WS C621E SAGE + dual Xeon Scalable + Apacer wide temperature RDIMM + modified JCAT NET Card FEMTO were gonna totally smoke all switches out there https://www.windowscentral.com/how-set-and-manage-network-bridge-connection-windows-10
  2. FYI - that 10% off deal is constantly available on a weekly basis from Wednesday to Friday, let's take a look at a few tips and tricks for importing S100 from Japan directly. First of all, there will be no warranty outside Japan at all but personally I believe that S100 won't go south within 12 months simply because it's made in Japan to begin with. Though we could spend about 2,600 bucks for purchasing two units of S100 rather than getting only one for £1,999 in UK. Pretty much like the difference between Victor and JVC, they're known as Melco internationally and DELA domestically. Hence we've gotta look for DELA S100 instead of Melco S100. Currently there are 3 sellers listed on Rakuten and all of them should be backordered, they're always showing the full retail price and here are the direct links to order them https://www.fromjapan.co.jp/en/special/order/confirm/https%3A%2F%2Fitem.rakuten.co.jp%2Fratoc%2Fs100%2F/N_1/ https://www.fromjapan.co.jp/en/special/order/confirm/https%3A%2F%2Fitem.rakuten.co.jp%2Faudiounion%2Fdelas100%2F/N_1/ https://www.fromjapan.co.jp/en/special/order/confirm/https%3A%2F%2Fitem.rakuten.co.jp%2Fyamada-denki%2F4218914012%2F/N_1/ Default currency is NOT Japanese Yen under most circumstances and therefore the currency conversion rate might be somewhat "less than desirable" if you will. Definitely change it to Japanese Yen (upper-right corner of any pages) right away after you've logged on / created a brand new account. Finally the currency conversion will be done by your own credit card company and most likely that's gonna be a better deal. S100 is already double boxed by default and the entire package should weigh almost 5kg, here's the link to Shipping Fee Calculator https://www.fromjapan.co.jp/en/estimate Shopping Proxy Service companies could very well be swamped these days. Almost everyone is trying to get their hands on surgical masks etc. for obvious reasons and the sheer volume of orders might keep their staff VERY busy. If you're living close to China like I do, it's a challenging year for the air cargo industry since the number of flights to specific regions should be greatly reduced. Novel Coronavirus in Asia, mysterious disease in Nigeria, Yaravirus in Brazil, there's no telling how long it's gonna take before things are getting better. Thankfully S100 ain't made in China and the production itself shouldn't be affected, though more and more confirmed cases were popping up over there https://www.japantimes.co.jp/news/2020/02/12/national/science-health/40-new-coronavirus-cases-cruise-ship-quarantined-japan/ BTW, here's an upcoming Ethernet cable (100Mbps only with 2 pairs of Gore wires) if you're also interested in getting something from Japan http://asoyaji.blogspot.com/2020/02/lan.html
  3. Here comes another trifecta FTW https://www.whatsbestforum.com/threads/melco-s100-audiophile-switch.29828/page-2#post-627616 Each Melco S100 should cost about $1,300 shipped (through "From Japan" with 10% off) when it's imported from Japan directly, that's like $2,600 for a pair of them while we don't get any kinda warranty outside Japan. Stock SOtM sNH-10G is $800, add $200 for the upgrading internal wires and EVOX caps. For upgrading its 25MHz clock instead of going for sCLK-EX plus another external clock with Habst clock cable, base price (without VAT for customers outside EU) should be around £125 and the grand total (without VAT again) is £375 plus shipping https://www.fidelityaudio.co.uk/network-switch-upgrade-4616-p.asp The difference between C4 and C5 (without VAT) should be about £125 (i.e. 375 - 249.17) so the grand total for modifying a switch with C5 (without VAT) should be around 500 quids plus shipping if that were actually available in the future https://www.fidelityaudio.co.uk/clocks---precision-low-jitter-143-c.asp Roughly $1,650 plus shipping for that modified SOtM sNH-10G, finally we should be able to keep everything under 4,500 bucks. Then each Melco S100 requires 12V / 1A rail, maybe it's a good idea to power SOtM sNH-10G and C5 with separate rails? Audiophile Ethernet cables seemed to be indispensable, stuff like Shunyata Research Sigma should be starting at $900 for 1.5M while we'll need quite a few of them since there are 3 cascaded switches https://shunyata.com/products/digital-cables/ethernet-digital-cables/ethernet-cables-venom-alpha-sigma/ Not too shabby IF we're able to get a glimpse of what SGM Extreme could offer?
  4. Foxconn sees full China production resuming late-February: source https://www.reuters.com/article/us-china-health-foxconn/foxconn-sees-full-china-production-resuming-late-february-source-idUSKBN1ZZ10B China blocks restart of Foxconn plants due to coronavirus: sources https://asia.nikkei.com/Spotlight/Coronavirus-outbreak/China-blocks-restart-of-Foxconn-plants-due-to-coronavirus-sources China's Shenzhen denies blocking Apple supplier Foxconn from resuming production https://www.reuters.com/article/us-china-health-foxconn/chinas-shenzhen-denies-blocking-apple-supplier-foxconn-from-resuming-production-idUSKBN2030I3 As the plot thickens, it's hard to tell if we're gonna face a certain degree of shortages while even Apple (reaching $1 trillion market cap at some point) might / might not have to think about a "Plan B" of some sort. IMHO it could very well be a gamble to resume production ASAP since numerous Foxconn employees will be packed inside the same factories. Pretty much the same deal for just about any other companies around the globe who must depend on the production capability / affordability over there. When a country's debt notably rose to 310% of GDP, let's imagine how tricky it could be to keep the ball rolling since they're dealing with that kinda $13 trillion economy. If they're actually losing the bet, one could only speculate what's gonna happen to the supply chain once we begin to feel the pain of (major?) cascading effect. Just some food for thought if we're planning to build something new this year, where do we (as well as the vast majority of manufacturers) source the parts after SHTF in China? Personally I might have to focus on food for the stomach at the moment since many items are constantly flying off the shelves every single day.
  5. https://www.whatsbestforum.com/threads/taiko-audio-sgm-extreme-the-crème-de-la-crème.27433/page-132#post-623214 Passive cooling for a setup like that while it's drawing 330W from the wall? Just wondering if that were such a good idea even though meticulous detail could be observed in terms of heat dissipation etc. CUDA offloading could be another avenue, though passively cooled GeForce might not be able to much. Besides, not sure if Intel C621 were compatible with Pink Faun I2S Bridge since other Intel chipsets should be no good.
  6. WS C621E SAGE might / might not support Optane DCPMMs but let's take a look together. I know what's going on in China these days but 128GB Optane DCPMMs should cost about 185 bucks a pop over there https://item.taobao.com/item.htm?id=591150702088 6 DIMM slots for each CPU and therefore we'll get 12 slots then, could we actually allocate 1 RDIMM (8GB - CTO only from Table 10) plus 5 DCPMMs (i.e. 8GB + 640GB for each CPU) by any chance? https://lenovopress.com/lp1066.pdf#page=10 Instead of 10-core Xeon Silver 4114, we'll have to go for 8-core Xeon Silver 4215 instead https://ark.intel.com/content/www/us/en/ark/products/193389/intel-xeon-silver-4215-processor-11m-cache-2-50-ghz.html Granted the latency of RDIMM should be FAR superior to Optane DCPMMs for obvious reasons, though we could actually take advantage of Optane for storage purposes in terms of OS / music library / Roon database etc. Is 6-channel memory support for Xeon Scalable family really THAT important? Most of those slots could be saved for storage if Optane DCPMMs were a higher priority.
  7. FYI - Roy compared Intona Ultimate to the latest 2020 model of Sablon Audio Panatela Reserva Elite https://www.whatsbestforum.com/threads/sablon-usb-cable-2020-model.29912/page-2#post-625197 It's starting at $650 for the unpowered version and $750 for the power version respectively http://www.sablonaudio.com/index.php/signal https://www.whatsbestforum.com/threads/sablon-usb-cable-2020-model.29912/#post-622874
  8. It should be no secret that Buffalo and Melco (or called "DELA" in Japan) are basically the same guys http://www.melcoinc.com https://www.melco-audio-masters.com BSL-WS-G2108M/A was the 1st generation https://www.hiendy.com/hififorum/forum.php?mod=viewthread&tid=94358 BS-GS2016/A was the 2nd one and obviously the design of S100 should look pretty darn close https://www.hiendy.com/hififorum/forum.php?mod=viewthread&tid=107184 Another audiophile here in Hong Kong already got his BS-GS2016/A modified by replacing the original clock with an OCXO, therefore that (25 MHz) clock should be simply hidden under the heat sink since it's placed somewhere close to where CPU could be found https://www.audioshark.org/lumin-169/lumin-x1-home-visit-14384.html https://www.hiendy.com/hififorum/forum.php?mod=viewthread&tid=118513 While Buffalo couldn't even hold a candle when compared to those giants like Cisco, they're still gaining quite a bit of experience after manufacturing a fairly wide range of products over the years. Therefore I could only speculate that catering to the audiophile market should be a piece of cake since they're already having access to plenty of resources to begin with. Maybe they could simply find a way to get the job done without relying on fancy clocking solutions? If the audiophile market weren't so niche in the first place, it's hard to imagine what we're gonna get from Cisco since their Catalyst 2960 Series seemed to perform reasonably well without even trying. Pretty much the same deal with motherboards, Asus didn't have to do anything special for their WS C621E SAGE and then Emile had to opt for that one since he couldn't really design a better motherboard for SGM Extreme. Even Antipodes Audio got what they're looking for https://web.archive.org/web/20180129153435/http://antipodesaudio.com/server-upgrades.html Speaking of industrial grade products, it's easy to get a "Cisco compatible" SFP without breaking the bank but one of those genuine Cisco products (NOT the ones from Linksys) could very well cost hundreds or even thousands of dollars https://www.cisco.com/c/en/us/products/collateral/interfaces-modules/gigabit-ethernet-gbic-sfp-modules/datasheet-c78-366584.html These guys are actually refurbished and we're still talking about more than 300 bucks a piece https://www.m4l.com/GLC-BX-U-I-Cisco-Transceiver https://www.servers4less.com/networking/transceivers/cisco-glc-bx-u-i And then here's something else with a fake S/N and it's off by 5°C https://edgeoptic.com/products/nortel/nttp07ffe6/ So many brands were claiming to be industrial grade with the right temperature range, there's no telling what / who could be trusted.
  9. FYI - @hols just shared his comparison between fully-loaded SOtM sNH-10G (with Cybershaft's flagship model OP21A for > $6,000 & Habst Digital clock cable for another $1,000) and Melco S100 (mine should cost roughly $1,300 as I mentioned before, no inputs for any external clocking options) here https://www.whatsbestforum.com/threads/melco-s100-audiophile-switch.29828/page-2#post-625788 Quite a few reviewers in Taiwan also talked about their own impressions after comparing the differences between SOtM and Melco, it's written in Chinese and therefore please give machine translation a try http://my-hiend.com/wp/?p=33234 Other reviews of Melco (written in Chinese / Japanese) also looked quite positive to me http://my-hiend.com/wp/?p=33194 https://review.kakaku.com/review/K0001204484/ReviewCD=1286778/#tab I was able to find quite a few owners of Melco out there and they also liked it https://www.whatsbestforum.com/threads/melco-s100-audiophile-switch.29828/#post-624513 https://devialetchat.com/Thread-Audiophile-Grade-Ethernet-Switches-The-new-generation?pid=89323#pid89323
  10. FYI - @hols just shared his impressions with SGM Extreme here https://www.whatsbestforum.com/threads/taiko-audio-sgm-extreme-the-cr%C3%A8me-de-la-cr%C3%A8me.27433/page-132#post-623029
  11. Since SOtM should be announcing their own motherboard in the (near) future, it's gonna be interesting to compare the differences between SOtM and ASUS ROG. Besides the challenges of acquiring a fanless chassis for a relatively large EEB motherboard, how about (partially) replicating SGM Extreme with WS C621E SAGE and Xeon Silver @ 85W TDP? It won't boot with UDIMM for a config with dual processors, though a single CPU should still work with D31.23185S.001 that's recommended by @Marcin_gps https://www.mouser.com/ProductDetail/Apacer/D3123185S001?qs=Cb2nCFKsA8prqNusSnCNZw== https://audiophilestyle.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/page/603/?tab=comments#comment-995194 Emile attempted to design his own motherboard for SGM Extreme but it just wasn't as good as WS C621E SAGE, therefore SOtM must have done something special or else it might not be able to beat that particular server board.
  12. Some audiophiles in Taiwan actually went all out to power their components with (used) industrial power supplies from Daitron / Cosel / ETA etc. They're reporting tremendous improvements after going for the 600W (12V / 50A) or even 1200W (12V / 100A) ones despite having those always-on cooling fans https://www.ptt.cc/bbs/Audiophile/M.1546187053.A.9FC.html https://www.stsd99.com/phpBB3/viewtopic.php?f=61&t=2722&start=60 http://www.my-hiend.com/vbb/showthread.php?5404-走向超值而極緻的-HI-FI電腦訊源(連載)/page485 Things were getting even better once they added 3 (also used) giant caps such as Electronicon E50.N23-185N50 but they're well aware of the potential risks involved http://img.alicdn.com/imgextra/i1/136635359/O1CN011pSSyzLgeQx2FfO_!!0-item_pic.jpg http://img.alicdn.com/imgextra/i2/136635359/O1CN011pSSyxxr1HQUayd_!!0-item_pic.jpg http://img.alicdn.com/imgextra/i4/136635359/O1CN011pSSyyAWZN8418l_!!0-item_pic.jpg It's kinda like a recurring theme of some sort, industrial-grade stuff (even though they're SMPS instead of LPS) might tend to perform on a quite different level IMHO. Of course none of them seemed to be familiar with Paul Hynes / Dr. Sean Jacobs etc. so it's hard to tell if they're actually the "real deal" or otherwise.
  13. @justubes already talked about SE-120 before, that official upgrade for REF10 was provided by Mutec https://www.whatsbestforum.com/threads/reality-is-cruel-cybershaft-new-ultimate-ocxo-10m-clocks-shootout-op20-vs-op17.26610/page-8#post-612931 https://www.whatsbestforum.com/threads/reality-is-cruel-cybershaft-new-ultimate-ocxo-10m-clocks-shootout-op20-vs-op17.26610/page-8#post-615223
  14. I didn't link to iPower X since it's still password-protected at the moment https://ifi-audio.com/products/ipower-2/ Previous gen could only deliver up to 18W while the latest ones could reach as high as 24W depending on the voltage. And then previous ones would have some kinda claims like "Up to 10x quieter than the original iFi Ultra-Low Noise AC/DC Adapter" printed on the side of the box while it should be changed to 20x this time. Though not exactly sure if that were just theoretical number or something And then I didn't mention this clip below since it's only available in Cantonese without English subtitles, the part about iPower X should begin around the 11:30 mark https://www.facebook.com/CASWorkshopHK/videos/911580552594520 Basically they're asking for $100 while we'll get fewer accessories in return, different removable plugs for multiple countries used to be part of the package deal while there's only one plug now. And then most likely we won't be able to reuse those plugs from previous generation. The adapters for DC connectors are still included, though.
  15. FYI - here's something new for 100 bucks that could work with either DXP-1A5S or DXP-1A5DSC https://fccid.io/RR-iFi-iPower-X-001 https://fccid.io/RR-iFi-iPower-X-002 https://www.price.com.hk/product.php?p=438876 https://www.facebook.com/sk.storehk/posts/2537748199816889 https://www.hkepc.com/forum/viewthread.php?fid=124&tid=2539565 For instance, get the 15V iPower X and DXP-1A5DSC for something that needs a double-regulated 12V / 1.5A rail so that we'll have 15V → 13.5V → 12V 12V iPower X → 10.5V → 9V 9V iPower X → 7V → 5V It's somewhere between the price tag of POWERADD PP2 & PP5 (i.e. $89.99 & $105.99 respectively) https://www.amazon.com/POWERADD-Pilot-23000mAh-External-Smartphones/dp/B015OAJFOC https://www.amazon.com/POWERADD-Delivery-30000mAh-Smartphones-Chromebook/dp/B07WVTKTYD According to @str-1 both PP2 & PP5 should sound the same https://www.head-fi.org/threads/hugo-m-scaler-by-chord-electronics-the-official-thread.885042/page-657#post-15387361 Just another option for those of us who might find it somewhat difficult to get PP2 & PP5 because of issues related to shipping batteries etc.
