A novel way to massively improve the SQ of computer audio streaming

[seeteeyou]

Here's yet another "secret weapon" from Apacer that would cost even more

The First XR-DIMM DRAM Module with RTCA DO-160G Certification From the Leading Supplier of Industrial-grade Memory

Anti-vibration could play a role when it comes to the SQ department?

 

 

Though we'll be limited to an industrial motherboard (wide temperature, too) like this one

Most likely some manufacturers of music servers are keeping an eye on XR-DIMM and planning to implement this in the future?

Let's see if TRX40 AORUS Xtreme were fanless / getting the best VRM again? Though Threadripper 3000 Series wouldn't be "cool" enough for passive cooling since previous ones were more like either 180W or 250W.

 

IIRC one of those 95W TDP processors from Intel could get away with a single SR7 rail @ 12V/5A when we're only running Euphony / Stylus, maybe 12V/6A is a safer bet for 3950X? And then we're also expecting Super12 (with 12V/12A by combining 3 rails) to be shipped by the end of 2019, that's gotta be enough over-provisioned current then.

Thank you and welcome to the What's Best Forum. If you are the same Austinpop as on the Audiophilestyle Forum I would characterize your efforts as beyond modest. One of the driving forces moving the technology forward would be more appropriate.

 

Speaking of SGM Extreme, they weren't shy about showing us what the motherboard is

Processors were stated to be 1st gen Xeon Scalable with 10C/20T so the only possibilities should be 4114 / 4114T / 5115 with the same 85W TDP

Regarding VRM, "only" 7+1 phase for CPU and then 2 phase for DRAM

 

https://linustechtips.com/main/topic/850609-asus-ws-c621e-sage/

 

We can't really match their RAM but at the very least we'll get something decent from Apacer.

 

They said it's all about "noise management" and therefore the chassis etc. must have played a really important role. Finally it might take quite a few excellent rails from the usual suspects to rival their PSU that should be hardwired internally.

 

It's kinda funny to read that similarly priced Aurender W20SE couldn't match SGM Extreme so it might take quite a bit of time and effort to beat the king

In the end maybe the motherboard itself doesn't have to be THAT special then? No matter what there will be switching regulators here and there

I found PP2 on NUC and SR4 on HMS to be slightly better than SR4 on NUC and PP2 on HMS, which is very interesting in its own right (I was very surprised the SQ was close as it was)

 

Thank you.

[seeteeyou]

Their specs claimed that PP2 should be good for 4.5A and that might be a better choice if a high current draw were needed?

 

They also have this PowerCenter II for $212.49 and its 12V output could have the potential to feed a powerful CPU

Outputs: 4x USB 5 V - 2.1 A (Max); 2x DC 9 - 12.6 V / 15 A (Max); 1x AC 300 W (Max)

 

Or even use its AC output to power another PSU? Though the quality might not be as good when compared to their tried and true PP2.

[seeteeyou]

Maybe take a look at these guys for starters, it's more about stringent quality of components that could withstand less than ideal environments. Then it's gonna be a walk in the park when they're working under normal conditions, pretty much like over-provisioned CPUs / PSUs with a really low utilization (clock speed / current draw)

Let's put it this way, they just don't have to bother with planned obsolescence whenever they're designing their industrial grade products.

 

How about an analogy when it comes to the differences between the two - consumer versus industrial? For run-of-the-mill dried blueberries, they've gotta "sweeten the deal" with apple juice concentrate in order to mask the inferior taste. And then the frozen ones are gonna fall apart once they're defrosted.

 

What about these tasty "wide temperature" blueberries? So have yourself a berry little Christmas now

Ironically we better eat something that came straight from the soil instead of "industrial foods" that are already soiled. If it came from a plant, eat it; if it was made in a plant, don't.

Basically their flagship UBER model could provide up to 3.6A continuously, pricing is the same as Dr. Sean Jacobs' DC3 without any upgrades. That means roughly twice the current at the same price but there's already Farad Super3 @ 3A with such a nice price tag

Word of advice to owners of HMS and TT2: don't make the mistake of auditioning a DAVE with the HMS. Here again, I was actually unprepared for the magnitude of the improvement. I was expecting something fairly subtle, but what I heard was gobsmacking.

 

Rob already stated that DAVE 2 wouldn't appear in the foreseeable future since he's still working on his DX amp(s) as well as DAVINA, does it make sense to bump the Pulse Array design from 10 to 20 elements first and then get a pair of nice BNC cables later?

 

BTW, it's interesting to read something from an owner of $105,000 / pair amps + £130,000 / pair speakers since the source turned out to be Dell XPS 13

To hear the Dave and Blu2 at their best, power and RFI have to be taken into account. Separating the Dave and Blu2 physically, and especially their mains supplies has been a huge improvement. The Opto-DX has allowed this. The Opto-DX has also eliminated the need for a dedicated audiophile streamer.

 

Though adding OPTO•DX would also require an extra pair of BNC cables while Dan's getting to ready launch RF•STOP by the end of this month

I have been building some DC cables for my personal use and I have tried many many conductors with various gauges including copper, silver, and silver plated copper, stranded and solid core.

I found that the most important aspect to SQ is gauge, go for the largest gauge you can regardless whether it is solid core or stranded. As for copper vs. silver you really need to try in your system to find the tonality that matches best with your system.

I found that the LT3045 adds a bit of clarity when used with LPS-1 to power my switch. The improvement is subtle, in contrast going to a silver thicker gauge on the DC wire is by far more effective.

 

Though the thickness of 12AWG wires would end up with something like this

You can use heat shrink and leave the barrels off. I did that with some very short pieces of solid 12g Neotech hook up wire, separated by air. Don't look like much but sound great. Don't forget to use a small piece of shrink over the live solder joint and any exposed live wire so if any bending it won't short the neutral. Then a big piece that snugs the screw part of the plug with the cable.

 

Question for @Nenon who's a fan of Mundorf, what if we kinda "replace" those barrels of DC connectors by wrapping some Mundorf foils around each plug?

Their latest model should be CS710-CF and 32GB ones are about $330 on Mouser, did you try previous generations yourself and just wondering if the impact were as significant as what ECC RAM could bring to the table?

It's an odd device, you would not expect some obscure item hidden away on a chinese marketplace to be anything special but they seem to have made a decent effort to be audiophile oriented, not just some device for making basic sound.

 

That's why we'd like to call it 臥虎藏龍 or Crouching Tiger, Hidden Dragon in English.

 

So many interesting products over there while they're virtually unknown to international customers. Here's an example with four SC cut OCXO

They've got plenty of options to optimize the SQ department of RoonServer

 

http://www.headphoneclub.com/thread-732005-1-1.html

 

One of their customers tried AudioLinux (but not Euphony / Stylus yet) before and that's no match for JAOS, though AudioLinux might not be as optimized as what Larry did.

 

Even running the Server Core flavor of Windows Server 2019 in RAM (with Audiophile Optimizer + Process Lasso + Fidelizer) still wasn't as good as what JAOS could offer, though there might be language barrier unless we're adding this stuff ourselves

Sometimes it's also fun to read direct listening impressions on other threads, especially when we're all about a collection of impressions on this particular thread here. I saw that JAOS actually consumed less than 1GB of RAM with 28 processes / 265 threads / 5359 handles, therefore having only 4GB of Apacer RAM should be good to go.

 

IIRC some of us actually opted for the superior SQ of Euphony / Stylus while forgoing the strength of Roon, maybe there's still a chance for Roon to shine again?

Thanks @Nsxturbo for your awesome answers, I guess that giving up 4 cores and go for Silver 4215 wouldn't be such a bad idea since Optane DCPMM could be lots of fun.

 

How about your fanless Micro-ATX chassis since we also wanna know which one is a good fit for that particular C621 motherboard? Just wondering if that were adequate for passively cooling 12-core Xeon Scalable with 85W TDP.

Graphene isn't listed but it is claimed to have a conductivity 100x of copper.  Note that silver is 5% more conductive than copper and that purity matters.  UP-OCC grade purity is the purest form of silver or copper that is commercially available (guaranteed to be 99.99997% pure).

The connectors are a mix of IeGo and Furutech. All soldered connections and compression fittings are coated with Perfect Path Total Contact graphene contact enhancer.

 

BTW, I've had good results with this graphene paste on the pins inside molex connectors of SOtM devices and other digital components-- though one must take care not to over-apply it at the risk of shorting the pins.

It's powered by the graphene lipo which has a very very low impedance and coupled to 4 LT3045's ....😀

I've only tried Mad Scientist's, I thought it made a huge difference, better than Furutech Nano Liquid, Stabilant 22 gel concentrate or De-Oxit Gold 100% or just newly cleaned plugs and connectors.

 

If graphene were actually THAT good, here's a little something from AZ

As a thank you for all the interest we are offering our GM USB for the introductory price of $849 for a 1M. We would have to sell a separate GM DC cable for at least $399 (yes we are working on this!) so you can see the value this cable brings, not to mention attaching 4 effectively 9 gauge conductors into a USB connector (I go through a lot of eye drops...).

 

Graphene Matrix DC cable? Let's wait and see if that were able to beat Mundorf / Neotech then.

The Epyc 3000 on the other hand looks much bigger than something like a Intel NUC so I wonder if it would still sound as good given more parts/components being used which may result to more noise. The Ryzen 3900 sounds like the perfect CPU to be used in a music server. The TDP puts it just low enough to be used in a fanless chassis.

 

They do have something else that's as small as it gets

Though we'll have to add that conga-STX7 carrier board and it's gonna get so expensive just because we're paying for the flexibility of COM Express

This is what they're asking for another larger carrier board

I could see myself connecting HDDs to that USB CLEAN port and use it as my quality NAS, not the most powerful hardware for sure but even its Gigabit Ethernet @ 330 Mbps should be no biggie for audio purposes IMHO

To lower the noise of the USB, we had to lower noise on EACH rail. In total, USBridge Sig uses more than 30 LDOs. Even the SD card power rail has a dedicated LDO. There are zero switching elements on board.

A graphene DC cable would be most interesting.  I have graphene in various components and cables in my audio system, and I believe there is something to it.

 

A reputable seller just posted a decent deal that looked pretty dope

I've been looking for graphene (with silver etc.) headphone cables as well but unfortunately Cerious Technologies don't sell 'em. Have you ever tried these guys from the lending library?

No graphene but just wondering if this stuff were some kinda hype or actually a game changer?

This is an intriguing product, but more than I would pay for a headphone cable.  What most interests me here is the floating ground station. Given the experience with grounding other cables in my system, I would love to ground a headphone cable to my active ground block.

 

They do sell quite a few headphone cables with female 3.5-mm plugs for connecting ground cables, 3.3-m Atlantis Infinity turned out to be cheaper than 2.2-m ones

Or just wrap this around your existing headphone cables instead

 

https://www.thecableco.com/silver-mini-wraps-pair.html

http://entreq.eu/info/ENTREQ_pricelist_2019_01.pdf#page=2

 

Someone also demonstrated how to do it with Wireworld's flagship Nano-Platinum Eclipse

 

https://medium.com/mad4u/telosgnrm-17dffecb6790

 

Maybe keep an eye on used ones for experimental purposes, usually the headphone cables should be under 500 bucks

We could actually get some bulk wires from our local authorized dealer, though it's just a bit risky to be on the street these days.

Similar in overall structure and construction these wraps are a natural extension to the performance enhancements found in the standard wraps. With particular attention given to the mineral mixture in the main pockets of the wraps themselves, as well as a dedicated ground point to further drain noise and field effects, these wraps offer an obvious and clear improvement in almost every application.

 

A pair of Infinity Silver Mini Wraps would cost $160 and grounding DC cables with JSSG 360 ^ Infinity would be such a catchy name

 

https://www.entreq.com/news-17217671

 

Grounding non-Habst clock cables are also fun since Habst ones seemed to work quite well whenever they're grounded, same deal with coaxial cables between Hugo M Scaler and DACs because of all that RF noise.

The DC Power cable are at least as important as the AC Power cable is for the sound and result.
We now introduce a wide range of DC Power cords.
From Primer to our top model Atlantis.

 

They posted that back in February 2019 but somehow that didn't seem to be available anywhere yet.

 

Obviously we don't really HAVE to pay for those wraps or expensive DC cables, just steal their ideas and see how it goes.

It probably won’t be until early next year that I acquire a Super3. It was truly awesome though that I got a chance to hear one in my system so I’d have a better idea of what to expect. 

 

Supposedly they're working on Super12 with 3 rails but for some reasons this link should be removed at some point, maybe we'll also see something like Super15 with 3 rails as well?

I also enjoyed reading your listening impressions here when you're describing the synergy between Wireworld Gold Starlight and Shunyata Research Alpha

BTW, do you or any of your buddies nearby have Mutec REF 10 or any kinda 10MHz reference clock? So far nobody actually experimented with replacing a plain vanilla 75Ω clock cable with ODX yet, that's why it might end up to be another surprise.
