@limniscate and I had a chance to compare the TLS Reference 1 to an SR7 this past week.  Both are double-regulated supplies.  I'll be posting more details soon in the Reference 1 thread, but for now, I can reveal that the SR7 came out on top.

 

Quite some time ago, a little bird told me that the SR7 is also better than a Dr. Sean Jacobs flagship.  I can't name sources, so please don't ask.

 

Well, SR7 is now a legend.

We could pay Intel that kinda money to make a prototype of something VERY special, most likely that's a better bet than Asus or Supermicro etc.

 

I dunno, attacking the latency side while bypassing the CPU as much as possible should be a good place to start

 

PCIe Peer-2-Peer

GPUDirect RDMA

https://developer.nvidia.com/gpudirect

https://github.com/Mellanox/nv_peer_memory

 

A quality PSU with top-notch performance is still relatively hard to come by, we still dunno if Dr. Sean Jacobs' flagship or TLS Reference 1 were as good as SR7 DR or otherwise.

 

Is it realistic to expect plenty of us who are happy to share the costs of R&D in terms of making the "best" motherboard for AudioLinux? We'll have to find out if Neutron Star 2 were even better than stuff like Connor-Winfield etc.

 

Kickstarter is right there...

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.

 

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

I would not assume how well it will work.  The Mac Mini still  has the internal SMPS and PWM fan.  Some of the testing has been done using workstation class machines.  Lots more to learn here.

 

But you are using NUC i7 with Fan and SMPS and like the sound more than UR/JS2.

Yes that is true. I warrant caution with all of this. There is a lot more to report on. I will talk more later today about my system.  I will not keep the current NUC I AM TESTING IN MY SYSTEM. 

 

i have a fanless case in house and a NUC on order.  

 

There are are some things about the sound in my system that are not where I want them to be.  

 

I really want to know how the impact of LPS and fanless NUC7 to SQ compared with stock power supply and fan. I have a slight mistrust that should not be too much ...

Better psus (in my case PH SR4s) and  fanless cases brought major improvements to my NUC server and endpoint. Most listenening reports confirm this. 

 @bobfa said NUC (without mods and adds) is much better than MicroRendu ("a very big yes", he said in preference between them). If a fanless case and a LPS give a big impact too, the conclusion is very easy: a NUC fanless + LPS ($1k) is completely, massively and unquestionably superior than Ultrarendu/JS2 ($2k).

This makes it seem like you are cheering for your favorite sports team.  😁

 

It may well be that after enough members have directly compared the NUC+AL against the UR, we have a consensus, or perhaps not.  Ideally, we need lots of input from members with differing systems before statements like yours should be made IMHO.

 

 

 

Lol. You're right. But don't take me wrong. I am of Arm-NAA-Combo Team (Sotm in my case) :). I really want this new solution (NUC + AL) not to be as superior as they saying.

Is really unbelievable a simple NUC can be better than SMS200Ultra+TxUltra or Ultrarendu+Iso-Regen.

Well NUC + AL has been very favorable compared with the Zenith SE, so that says a lot

 

Everything is still inconclusive for me.

@austinpop has said before, Zenith Se is not better than Sotm Trifecta, but he prefered Zenith because it has less cables.

In a blind test against the Nuc, he choosed Zenith.

 

The only thing I'm sure, the CYJ seems the best bang for the buck of all times.

OOPS !

 I have corrected that slipup in my post.

 As your thread is so large, it would be nice to see a spinoff - The Best Of.

Perhaps posts selected by the many participants in your thread as being the most interesting /innovative and helpful?

 

The conclusion should be the ULTIMATE C.A.P.S. v.5 (or A.S.P.S v1). 🤗

He only liked the ZENith SE better on my system versus his NUC and Adrian's DS-1 and has never said that the SOtM Trifecta is better than the SE. 

 

My english is not good, but what you understand from its words:

 

”Findings

 
Let me first dispense with the most obvious and financially most attractive comparison: could the Zenith SE standalone replace my spaghetti chain? If so, I could sell my entire trifecta, and recoup most or all of what I paid for the SE. Sadly - the answer is an emphatic NO. While the SE bettered the trifecta in terms of the traits described above, especially dynamism and weight, there was also a profound sense of loss for the air, dimensionality, and resolution that is so characteristic of all the clock improvements. This was not surprising, nor unexpected, as it's what Roy found in his evaluation too.“

For those that might be interested, I have posted my initial listening impressions of the sMS-200Ultra Neo with SOtM's latest allegedly low latency V0.4.5.1 firmware here:   

 

 

(In summary, a definite step up in SQ, but maybe a minor HF issue?)

 

 

I have the same problem with hqplayer. How you made it work? I click the cog, reload, and nothing happens. It keeps loading blue circle forever. It simply can not find Hqplayer.

Restart Eunhasu, hover the cursor over the HQPlayer logo (do not click), on the right-hand side under the text "Control HQPlayer NAA" you will see a little cogwheel symbol, this indicates "Config HQPlayer NAA" when you hover the cursor over it, click this, then follow instructions to re-load the HQPlayer app.  Like many things, it is very easy when you know how.  (It would have been nice if SOtM had warned about this and provided some instructions)  Good luck!🙂

Doesnt work... 😫

The problem here is that your finding (that the SPS-500 beats the LPS-1 and LPS-1.2) is the opposite of what many others here have found.

Alan

 

Hans Beekhuyzen, when reviewed LPS-1, compared exaclty the same quality of Sbooster MkI, each one of yours own strenghts. And when reviewd SMS200Ultra with SPS500 couldnt hear any difference with Sbooster MKI. 

So, they should have the same SQ. And you can prefer one or another.

 

Audiobacon review https://audiobacon.net/2017/11/18/sotm-sms-200ultra-network-audio-player-sps-500-power-supply-review/ gets the same conclusion.

Buy at your own risk.

 

Before you consider this - look at this post below about this being potentially incompatible: https://www.computeraudiophile.com/forums/topic/30376-a-novel-way-to-massively-improve-the-sq-of-computer-audio-streaming/?do=findComment&comment=902647

 

 

Did the Hyper X worked for you, Rajiv?
