Sorry I've never owned an SOtM sMS-200Ultra, so I don't know the answer.

I posted this elsewhere. Worked for me. Hope it helps.

 

I highly recommend doing the upgrade via an external PC/memory card. The update took me 18 minutes. I turned off the SMS-200ultra neo, unplugged the USB and master clock cable, did the update via download to a PC and micro to USB card (18 mins). I plugged the card back in and went to the IP address. 4.5 shown as the version. I powered down once more, plugged the cables back in and started the unit once again (just to be safe). Roon play perfectly without adjusting any settings.   The instructions link for this process is buried in the instructions: http://docs.sotm-audio.com/doku.php?id=en:eunhasu:burn_sdcard_image  

 

To be safe I did not use the original 8GB SOtM card. I purchased a 16GB class 10 card.

Question:

 

First,  my apologies if this has already been answered as I am still working my way through the 500 pages of great information. 

 

With a Chord DAC (Qutest) and the Hugo M-scaler, does an SOtM USBultra still add value?

 

My setup is as follows:

- i5 small green computer (separate room)

- Netgear nighthawk router (separate room)

- SOtM sms200ultra neo SE with master clock input

- SOtM master clock (only connected to SOtM player presently)

- Chord M-scaler (just ordered)

- Chord Qutest DAC

- Pass Labs XP10 preamp

- Pass Labs XA30.8 amp

- Focal Maestro speakers

 

Thanks in advance for the insight.

Your sms200Ultra already has the sCLK-EX clocking board in the the tx-USBultra, so I don't believe there is any added benefit.

Can't answer exactly but the ISORegen still improves the sound on a UltraRendu into an M-scaler here ?

Yes, I believe it does if you use a Paul Hynes SR7DR to power it.

Your system looks like a trifecta: Router-sms200Ultra Neo-txUSBUltra.  Hence I guess the effect of the txUSBUltra would be positive.  However, now the limiting factor could be the DAC.  Also, an NUC7i7DNBE powered by the SR7 may outperform your PC + trifecta system.  You may see austinpop's post in the 1st post of this thread.  Check the index in the post.  His system was not exactly yours but close enough.

I'm curious to know how NUC7 sounds using windows optmized and hackintosh compared to Audiolinux.

it's hard to have an apple to apple comparison if NUC must be used.  The reason of using NUC as an endpoint (for example) is for its barebone nature, up to the point that only RAM is installed.  For Windows optimized PC, usually the OS is installed in the HDD or SDD.  Also, there are lots of optimizations for Windows.  It'd would be easier if you may specify the optimization.  I know nothing about the hackintosh.

 

A reference:

I used AO+Win2016Core+HQP before,  and I'tried using the same PC with AL(LXQt)+HQP to the same set of downstream hardware latter.  For that particular PC, AL sounds better to me.

 

Hope this helps.

Guys... The sr7 is not the only good sounding PSU on the Market. At the moment you are just building legends instead of beeing open minded.

 

If you want to have a realy good setup you need a supreme class psu at every important part. In my setup i use 20! That are sounding close to the top-class sr7. Thats a much bigger step than only one...

Are you meant NuC AL is better for endpoint than Core server?

That PC I used for comparison in my post was not an NUC.  Hence I could not answer your original question directly.

 

In my case, my NUC AL(headless) endpoint sounds better than my WinCore2016 server.

The only problem for most of us is that the SR7 is unobtainable, only a lucky few can obtain one.

I agree.  I'm not one of the few.  Just wanted to point out something for somebody struggling to read through 500 pages.

Sunny, what other supreme class PSUs, besides the SR7, and can be purchased (not DIY) sound the best in your experience?  Thanks:)

Windows Server 2016 Core plus AO has always gotten a lot of praise.  So if AL (LXQt) sounds better that is very promising.

Beside diy? Thats really hard. Because the most available even high pricetag psu have a lot of bottlenecks inside. 2-3 years ago i spend a lot of time at home with the  js-2 of a friend. It was a good benchmark for me while i checked out more than 40 differend designs. The big plus... : its available and for the price of a sr7 you can buy  2....

I still thinks highly for the Win2016Core+AO.  However, the PC matters much in terms of the RAM, the SSD/HDD, the cables, ..., etc.  The slam dunk of the NUC as an endpoint is now only RAM matters because the rest was not being used.  From what I have read in this thread, the sensitivity of RAM to the SQ is not high.  I stand corrected.

 

Another great thing of the NUC is that one may power it through the "cheap" LPS-1.2 to provide very decent SQ.  One can wait very patiently for his ordered but not yet delivered SR7.

@bobfa thanks for posting your journey with this. I just found the HQ Player trial, from in built player. A more rounded sound with a bit more bass. Highs are more even. Not had much chance to play around, just enjoying the music..

Hi Guys, I have $1000/£1000 for upgrade my system but not quite sure where to put the money in. I have SOtM-200 with Ultracap LPS-1, Chord 2qute with MCRU power supply, Passive Audio PC with linear power supply, PMC 26 with Naim Supernait 2. The cables are all high quality.

 

I am not looking for extra magic or more details, I am more up to the smoother and darker sound. Should I upgrade to Ultra Neo? TX-USB Ultra? Chord Qutest? Or save some money for the later pre and power amp upgrade? 

 

Thanks and happy listening for 2019!

Does this connector mean anything for the Neutrik 4-pin XLR output on SR7?

The Eidolic Peerless 4-pin XLR is the first production 4-pin XLR to use 99.9% pure fine silver for its pin material – an extravagant metal stock that is painfully slow to machine owing to its relative softness.  This material, at over 106% IACS conductivity, puts this connector at the absolute limit of electrical performance.
