I have been testing the JCAT Signature LAN Cable GOLD. It's really good.

Then comes the top performers, the SR Galileo SX and the JCat Signature Gold. To me, they were pretty much on the same level despite slightly different sound signature.

I do have the Duelund cap modded in the Sotm, which i feel imparts a strong sonic flavour of what such a quality cap brings.

 

You will void your warranty doing that, but am more than certain the improvements are above a Evox cap mod.

 

Speaking of caps, these guys turned out to cost £195 + VAT a pop these days

AFAIK the only (affordable) game in town for EPYC should be TureMetal UP10 (5,298 RMB / $775) from China plus an additional 600 RMB for their own custom-made heat sink

A Super Fanless Chassis from TureMetal: For DIY & 0 db Workstations

By contrast, the UP10 can house an ATX mainboard. Furthermore, the UP10 can remove 120 ~ 180 W of heat from a CPU as well as 170 ~ 250 W of heat from a GPU, enough for HEDT processors and top-of-the-range graphics cards.

 

TureMetal Builds a Fanless 32-Core EPYC PC with an RTX 2070

https://www.anandtech.com/show/15261/turemetal-fanless-pc-epyc-rtx-2080

Quote

The fanless system built by Turemetal is powered by AMD’s 32-core EPYC 7551 processor, listed as having a 180 W TDP, and GIGABYTE’s NVIDIA GeForce RTX 2070 video card with a 175 W TDP (355W total). These are both equipped into a Supermicro ATX motherboard, and then built inside a commercially available Turemetal UP10 chassis.

 

Dimensions of the motherboard must be under 30.5x32.5cm and therefore UP10 won't work for Asus WS C621E SAGE with 30.5x33.0cm at all.

Fairly decent prices for *REAL* SLC (not like others with only SLC cache, actually 983 ZET is powered by 1.5GB LPDDR4 DRAM buffer) drives, 480GB / 960GB = 1500 RMB / 3000 RMB (i.e. about $220 / $440) respectively and obviously 5-year warranty should be only valid in China

IMHO they should be awesome storage options for WS C621E SAGE etc. since all on-board USB / LAN / SATA / M.2 ports are connected to the chipset, therefore *ALL* PCIe slots and U.2 ports are connected to both CPUs directly

To power Samsung 983 ZET externally, not sure if stuff like this with Mini SAS HD cable were able to do the trick?

Not exactly easy to acquire BS-GS2016 these days unless we're willing to import them from their country of origin.

 

Regarding the motherboard, maybe it kinda depends on the cost of motherboard itself since it's a bit too risky to fry an expensive one?

 

And then we also have to figure out where the on-board Ethernet is connected to, perhaps its original 25 MHz clock ain't worth the replacement if that were connected to the PCH? Sometimes we're lucky to find something that's connected the CPU directly but it might not be that common to begin with.

 

Ultimately we still have to take this into consideration if local files were all we need for a motherboard with BMC (baseboard management controller)

But do we really need to spend that much money to buy both? I am not really sure. Even with both of these switches connected to my system, playing local files completely disconnected from the network sounded best. 

 


 

OTOH, we could also put our switches between the music server and the USB DAC instead

One of the desirable features associated with InfiniBand, another network fabric technology, is its Remote Direct Memory Access (RDMA) capability. RDMA allows for communication between systems but can bypass the overhead associated with the operating system kernel, so applications have reduced latency and much lower CPU utilization. This results in much faster network performance rates than traditional TCP/IP.

At some point maybe we've gotta leave TCP/IP behind since they aren't any good for our CPU(s) in terms of the least variation in load. Hopefully RDMA / RoCE / iWARP could get us one step closer to the "ideal" conditions of being unplugged / disco.

 


 

On the software side, there's a way to bypass the TCP/IP stack altogether

Now that we've got dual switches (or more) in series, dual regulators in series, as well as dual Xeon to dedicate a specific (physical) processor for HQP and NAA respectively, what if we're able to get dual DACs to synchronize? NOT talking about a dual-mono design with a pair of DAC chips here, I really do mean playing two "Schröderized" lossless files (will be explained below) on the same dual-Xeon music server followed by two separate units of DAC.

 

We're starting with a single lossless (i.e. in stereo / 2.0) first, and then ending up two separate mono / 1.0 lossless files

 

https://trac.ffmpeg.org/wiki/AudioChannelManipulation

QBvEePF.png

 

After that, each mono file will be "Schröderized" separately. 1st DAC will receive 2X the left-channel and then both RCA / XLR outputs will be connected to left-channel input of the amplifier. Similarly, 2nd DAC will receive 2X the right-channel and then both RCA / XLR outputs will be connected to right-channel input of the amplifier. I guess that maybe monoblocks could reap even more benefits?

 

For 1st DAC → qC1k528.png 

 

qC1k528.png ← For 2nd DAC

 

Of course the $64,000 question is whether the ASIO driver could handle 2 identical units of DAC on the same instance of Windows 10 or otherwise. This particular one could even handle 3 units

 

https://audiophilestyle.com/forums/topic/14657-first-multi-channel-dsd-playback-solution-with-mytek/

 

With the right cables maybe we could even go for double-stacking a pair of identical amplifiers?

A similar but fairly different concept

Essentially we should be aiming for stuff like a "dual-stereo" setup of some sort, though here's a genuine dual-mono DAC (Esoteric Grandioso D1X) just for reference
