- SR4 19V => HDPlex group 1 => various motherboard + 12V EPS/CPU

- Keces P8 20V => HDPlex group 2 => 12V external usb HDD

 @bodiebill is the P8 on group 2 a single or dual rail unit?

 

If single rail, have you considered switching it for the SR4 powering group 1, essentially switching the power supplies in the above usecases? 

[bodiebill]

The Keces is double rail. Actually 20V/19V + 12V/9V + usb 5V.

What you suggest could also be done with a double rail Keces I guess.

I did try the Keces on group 1 (mobo + CPU), but I prefer the SR4 there.

It's no surprise this one is a winner. The Lt3045s are doing their job.

 

Multiple parallel and serial Lt 3045 chains here improve SQ from both SR4 and LPS1.2 DC outputs. I have them on every device that consumes 3 amps or less..

more precise: that consumes 3 amps or less and settles for 15VDC or less 🙂

[Exocer]

So many questions. Thank you ALL for the tremendous help so far. Also, my apologies if this has been answered before.

 

I have an LPS 1.2 and I need to determine whether it makes sense to use it to power my Etherregen or to power my USB PCI-E expansion card (or Elfidenlity USB card).

 

This decision will drive my next LPSU decisions from MPAudio.

[Exocer]

Please disregard my previous post - I found my answer in this thread.  cheers

 

For anyone else with a similar question, this post REALLY helps break it down: 

 

Thanks @austinpop

I looking forward to when someone is starting to submerge the PC into oil and/or add liquid nitrogen for cooling 😀

 

And why not try to sink the LPS-1.2 powering a Rendu or SOtM into oil.  Have fun.

There is far too much pressure in Liquid Nitrogen will cause too much vibration

I need to buy two or three more dc cables for my various Pilot Pro battery packs, OPTO.DX and DXP-1A5DSC/DXP-1A5S units, and Chord M Scaler, and am wondering if I should take the opportunity to try one or two different cables from the Ghent DC-GAC4 Gotham cables that have served me well so far (I wouldn’t be surprised to be told to stick with the same cable).

 

Looking at the options Ghent has available, does anyone have experience hearing how the Ghent DC-7N16C (16awg solid-core) and/or Ghent DC-7N18C (18awg stranded-core) perform in the same device compared to the DC-GAC4?  I do of course realise that any feedback must come with the rider that this is all system dependent.

 

I will be using double-regulated DXP units between my PP5s/SR4T-19 and the OPTO.DX units, M Scaler and Netgear switch, so there will never be more than 16v passing through the dc cables and most of the time not less than 12v (possibly less if and when I upgrade to the EtherREGEN).  The DXP units limit things to 1.5A.

 

Thanks in advance for any feedback.

So strange! 

Do you notice anything better with this little card? In my systems it was a clear winner in every aspect. 

Yes it does improve on the existing MoBo ethernet connection. I use an etherRegen which works very well in my system,so my impression is that network improvements upstream of the ER are more subtle. The Tp link has been in a few days - so far I would describe the improvements as; richer harmonics, slightly better separation with vocals and transients.

Very interesting to read about your engineering experience, I taught mech eng practice years ago, unfortunately no longer have  access to a machine shop.

I think the next step is to move up to thicker DC cables. The problem is finding plugs. 
I don’t know if this is bigger than the  Oyaide one. Maybe you have to convince Ghent to manufacture his own plugs 😀

 

If people email him with a request, and many enough do, the result could be better DC cables. (Can they get better ?)

 

Same with AC cables if enough interest is there.

I think this cable is worth trying:  https://www.ghentaudio.com/part/dc-7n16c.html

 

It's pretty inflexible with the JSSG360 shielding, so order a little longer cable than you normally would.

[kennyb123]

I had previously reported being very pleased with the improvement brought to my Chord Hugo M-Scaler and TT2 by powering them with Pilot Pro2 batteries feeding the DXP outboard regulators.  I figured that these put me in a good enough place such that I didn't need to be in a rush to move Farad Super3 power supplies.  The Super3 has been on my want list ever since @austinpop reported very positively on it.

 

A few weeks ago I came across a listing for a preowned Super3 15V and I couldn't help but pull the trigger.  This model lacked the fuse and IEC upgrade, but came with a Level 2 cable in copper.  Swapping this for the battery + DXP powering the TT2 delivered a significant upgrade.  Most surprising was that it was actually quieter.  The Super3 stripped away some harshness and replaced it with greater density, liquidity, and naturalness.  Bass was considerably improved as well.  

 

I had initially powered the Super3 with a generic power cord.  A few days later I received a Shunyata Venom V12 NR power cord.  This improved things further - especially in terms of dynamics, dimensionality and openness.  

 

Last week I received another Super3 with a Level 2 copper cable - both brand new to match my other Super3.  This was substituted for the battery + DXP powering the HMS.  This delivered some nice improvements but there was a forwardness that got in the way of my enjoyment of the music.  I figured the Super3 and cable just needed further time to settle in.  By the weekend this forwardness had not dissipated so I wondered if the generic power cord had something to do with it.  I ran downstairs and pulled the Nordost Magus power cord from my Onkyo receiver in my AV system (the Magus was the predecessor to the current Blue Heaven power cord).  The Magus eliminated the forwardness and opened things up quite a bit.  

 

Really amazing what both of these power supplies have brought to the table.  Timber is being reproduced to a level that has had me gobsmacked.  The improvements are across the board and maybe close to being on par with what one might typically get from upgrading to a better DAC.  Better power cords can further improve the Super3, so I will likely be investigating that further at some point.

I think a DC cable should be star quad. That one is not, unless I misunderstand how it’s made.

Not to change the current topic but I have compared the following to setups with GentooPlayer OS:

 

Option A:

1. USB: Startech PCI-E USB-C card -  https://www.startech.com/Cards-Adapters/USB-3.0/Cards/2-port-pcie-usb3-1-card~PEXUSB312C3
2. Cable : AudioQuest Forest USB-C to B cable
3. NIC : StarTech USB 3.0 Gigabit Nic with Realtek Chipset

 

Option B:

1. USB: Motherboard USB 3.1 Gen 1 to Elfidelity USB Filter
2. Cable : Schiit Pyst
3. NIC: Motherboard input (through PCH)

 

I believe it is too early to tell which one is better but Option A is providing better imaging, larger soundstage and an overall "cleaner" presentation with some leanness compared to option B. Both sound great so far... I will give the card some time to break in but I do think Option A will likely be what I stick with until curiosity sets in.

 

Now, @bodiebill feeds his USB cards with proper LPSU power, so it is possible I have yet to scratch the surface of each card's capabilities.

 

Note: I am feeding both cards via generic cable from HDPlex 400W DC-ATX adapter. A better DC cable is on order, so is LPSU power for the server.

 

Note2: In order to get this USB NIC to work with GentooPlayer, I had to switch to the PF-ST kernel. Otherwise, the NIC went undetected. I did not check if it was the PCI-E card that wasn't detected or the NIC itself.

Interesting. Although hard to pinpoint which device does what as USB cards, cables as well as NIC's are different between both options.

 

And indeed I much preferred external LPSU power (with LT3045 cleansing) to the HDPlex 800W DC-ATX (even when fed by an SR4) for powering the Elfidelity.

 

And soon, I hope, my ASMedia ASM3142 10Gbps USB card will arrive so I can do a similar comparison.

yeah - too many variables changing at once. I would have likd to use the same cable but that was not an option. Even if I were to use an adapter there may be an SQ impact.

 

The NIC, I can switch back to the motherboard to do a more direct comparison.

USB 3.1 gen 2 is the better performing port and is indeed less tolerant to severe deviations from the USB cable specification. Some audiophile USB cables do deviate considerably and can therefor cause problem with newer hardware.

The stock USB port on the Extreme is probably the best sounding stock USB port I have heard. According to Emile, this port is based off of the ASM3142 chipset that he really likes.

 

Not that many motherboards came with their latest and greatest models ASM3241 / ASM3242 by default, though we could also get one of the following add-on cards below

Unless we're actually installing that card inside an external Thunderbolt enclosure, neither Gigabyte nor Sunix could accept external power without any modifications.

Hi clplarry, I bought Fibbr alpha usb cable weeks ago. I compared it to the Lush 2 cable In my system. The sound via Fibbr cable has a darker background, more details and layers. It also gives a smoother tone to all frequencies. All those benefits are more obvious in my headphone system. Off course above are only my own subjective listen experience.

 

Fibbr usb cable need some burning in before it start singing (mine took about a week). Power supply also critical(I am using UpTone LPS 1.2).

Despite that could only support up to 5Gbps, they're recommending some 10Gbps cables (i.e. Gen 2 instead of Gen 1) from Delock and Lindy over other brands. For those add-on cards with ASM3242 chipset mentioned in my previous post, we might also give them a try

Speaking of Adnaco, we could consider replacing the clock for ASM3142 / ASM3242 with the same OCXO clock from SiTime that's relatively affordable

The SiT5711 is popular and SiTime has not been able to get ahead of the demand. Regardless, we are pushing to get the oscillators sooner, but it seems that the USB Cards XE will not ship sooner than in July.  

 

However, I couldn't tell if that were supposed to be 25MHz (usually both Gigabit Ethernet and USB 3 stuff should share the same frequency) or actually 20MHz as indicated below

 

https://www.asmedia.com.tw/eng/e_show_products.php?cate_index=175&item=179

• External 20MHz differential crystal

 

Fortunately SiT5711 should be readily available in either frequency without having to place a custom order.

Almost forgot to talk about the "USB 3.0 only" cable between the Adnaco / EverPro "dongle" and the source in front of that. They're blocking all pins related to USB 2.0 (i.e. only those 5 "SuperSpeed" pins at the bottom of USB 3.0 A plug should be connected) in order to "enforce" USB 3.0 connections while even better SQ could be achieved accordingly according to their experiments.

 

Obviously DC 5V power must be fed to that "dongle" accordingly without that VCC pin connected

Similarly, 8 pins (A4, A6, A7, A9, B4, B6, B7, B9) are supposed to be blocked but it might be somewhat tricky due to the size of Type-C connectors

 

 

It's also important to keep the temperature down with a heat sink or two as shown below

I've gotta add one more thing as a disclaimer, we could use any USB gadgets or cables from Fibbr / EverPro / YOFC with our USB 2.0 DACs and DDCs but the endpoint / music server itself must have at least one USB 3 port. In other words, stuff like Allo USBridge Signature etc. with USB 2.0 ports ONLY won't work at all since that Broadcom BCM2837B0 SoC ain't fast enough.

 

In other words, most likely their products should have a different design when compared to Corning's USB 3.Optical cables with broader USB 2.0 compatibility on both ends.

 

BTW, I guess that maybe adding a "dongle" from Adnaco / EverPro might be able to solve a problem like this?

Just a word of warning - I have the JCAT XE card and found both of my Slimrun optical USBs would stop communicating with the DAC.  This problem did not occur with the Ryzen onboard USB ports, though.  Real shame as it was very effective otherwise.

Did you by any chance remove the jumpers from the card? I wonder if that's the cause.

Did you by any chance remove the jumpers from the card? I wonder if that's the cause.

I tried both ways (USB port power on, and off).  On other USB ports, powering it internally/externally didnt effect its stability.

Just a word of warning - I have the JCAT XE card and found both of my Slimrun optical USBs would stop communicating with the DAC.  This problem did not occur with the Ryzen onboard USB ports, though.  Real shame as it was very effective otherwise.

That's interesting, thanks for sharing. The AMD B450 motherboard used here includes a USB 3.2 Gen 2 port from the PCH. The B450 (and upcoming B550) chipsets are produced for AMD by Asmedia, so I suspect these ports are close to the ASMedia 3142 in quality and function.

 

The new B550 boards will have 4 USB 3.2 Gen 2 ports direct to CPU, as opposed to the 4 USB 3.1 Gen1 direct to CPU ports on the current B450 boards. That's great, but it will be a bummer if the Monoprice fiber cable is no longer compatible with them.

 

When I get the time, I'll try the Monoprice Fiber cable with the onboard USB 3.2 Gen2 port. It is currently disabled in the BIOS.

Speaking of Adnaco, we could consider replacing the clock for ASM3142 / ASM3242 with the same OCXO clock from SiTime that's relatively affordable

Thanks for sharing. The power supply could be managed via a PCI extension cable, Then cutting the power ribbon cable out and replacing with the dedicated power one. Which might give a very good and economical solution for the USB out.

 Do we know what power the USB card requires from the bus, 3 or 12V?
