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

this NUC makes much obvious things like HQ Player SRC filters and dither options.  And now I absolutely can not stand HQP PCM>DSD conversion.  For reference, folks should know I have a heavily modified Singxer SU-1 feeding I2S to a Holo Spring Level 3.

 

I 100% agree about the filters and conversion.

I also have a modified SU-1 but am not sold on it with the NUC yet.  I just started doing some comparison with both the tX-USBultra before it and out all together.  I think I should spend more time with it.

I measured my NUC7i5BNH it has M.2 SSD for ROCK OS and second SSD for music.

This is with regular 44.1/16 no DSP

19Vdc average 0.57A (10.83W) and peak 1.5A
15Vdc average 0.69A (10.35W) and peak 2.1A
12Vdc average 0.81A (9.72W) and peak 2.8A

Average is during play to Roon endpoint. Peak was during start up.

It sounds fantastic! :D

 

Fantastic with your ISO REGEN? Less fantastic without?

 

 

Would be greatly interested in your observations/impressions of your microRendu vs LarryNUC without ISO REGEN (whenever you get the chance to warm up the microRendu)..

The quad core sounds a bit more resolving in the mids to me. I enjoyed listening to this machine and felt sad to see it go!

That's not what I wanted to read ?. I was very close to ordering the pentium.

 

Oh well, I am about to go and pick up my celeron NUC from the post office. My akasa case doesn't arrive until mid December though ?

I've removed the ISO Regen twice to test SQ without it. Twice it has gone back in.

 

Did some folks report Sotm tx-ultra was redundant in their setup ? I have neither iso regen nor sotm and yet it sounds fantastic and can't think of it sounding any better. How much difference do you think you gained with iso regen ?

Thanks Larry. I guessed this may be the case.

The ISO Regen adds clarity. Pianos and guitars are less wooly.

Have you ever had an ultraRendu (not micro) in your system?

Having the ISO Regen adding clarity to this new NUC endpoint doesn't give me any confidence in it's supposed superior SQ abilities considering I found the ISO Regen a detriment to SQ in my jetway single server sCLK-EX NUC system. 

 

Picked up a new 8GB memory styx.  Look forward to trying out AL loaded to memory next month.

Interesting how the efficiency is greater (lower wattage) at 12V than at 19V.  9_9

My NUC is coming and I have an LPS-1.2 and I need a DC cable between them.

 

Anybody may advise me the dimension of the DC plugs needed for the  LPS and the NUC7CJYH?

5.5/2.5

 

You can buy adapters if you have 5.5/2.1.

To this:

Chain = AL NUC [R-Core 19V 5A LPSU > VBus2 > IFI Mercury 3.0 > Adapter > USB B power injector [R-Core 8V 6A LPSU >> DC 3.1 PoE >> 7V2 1A LT3045 >> 5V 0.5A LT3045] > SingXer F1

 

A bit of a simplification.

 

Result?

The new chain has a slightly bigger sound field. There is an increase in dynamics and detail.

 

All positive?

With well recorded material yes. With some tracks then a sibilant edge is more apparent.

 

 You need a larger value normal type electrolytic capacitor in parallel with the input of the 5V  LT3045 (try 100uF 16V for example) to obtain a more tonally balanced presentation. You have in effect a small increase in  upper HF detail at present. which results in a bigger soundstage, but often results in increased sibilance as you have noticed.

For my listening comparison, I simply substituted the NUC for the sMS, keeping the LPS-1.2 as the power supply for both.

 

How did you do it?

UltraCap™ LPS-1.2 (can output only 1.1A)

NUC need about 2,5a with 12v

I didn't do anything.  It works the way I described plug and play.

You are misinformed. The Pentium NUC needs 10 watts, not 30. The LPS1.2 delivers 13.2 watts.

AL preinstalls the most important audio services and applications like Roon and HQPlayer (and in lxqt version Logitech Media Server, Squeezelite, MPD, UpnP for MPD) so it works out of the box.  These applications are already partially configured. 

I thought I'd seen options for things like LMS/Squeezelite in AL headless 0.5, not just lxqt.  Am I wrong?
