Peter,

Definatly keep posting here.
The CA thread is interesting but can be fustrating sometimes.

A lot of folks here use NOSs so here there are more likley to be relevant observations for NOS systems here.

Having said this, I cannot contribute for a week or so as Im half way through a PC power supply build  unhappy but will be back to this topic when the PC is running again.

Cheers Nick.

Tim hi,

Im using  A: B-W-Y-R, B: B-W.
Will give Peter's other config a go. I have been putting some hours on the cable to burn it in so havent tried anything else as yet.

The UPS Elves deliverd a Lush^2 this morning  Happy

Its way too fast for a fast first post really, but bare with me. After a few hours of run and using settup A: B-W-Y-R, B: B-W.

First, runing seems  important the sound is changing "in front of my eyes" as it were. Running in happened with the Lush^1 for me, I just did not get on with it for about about 3 weeks then it ran in and it sounded great. The Lush^2 is changing quickly right now BUT the starting point in terms of sound quality TOTALLY different, the Lush^2 is absolutly brilliant compared to the Lush^1 !

WOW its a game changer, time to recalibrate my expectations of how music played at home can sound. Its that much of a step.

How does it sound just now ?

Detailed, transparent, extended, conveyes emotion, dynamic, less coloured, huge scale - Very real and highly musical.....

What a cable Peter, it's a fantastic achivement, many thanks.

  sounds good ! sounds good !

Ps, One point to keep in mind is that Manis USB stream is likley to be of unusual quality his stealth II sq is very different to standard.

Nah, the improvement isn't exclusive to my Mach II with your clock upgrade - there's a similar improvement in my office system, with my standard home-built x99 audio PC (as close to a Mach II as I could get it).

Look forward to hearing your thoughts over the weekend.

Mani.

I had made an asumtion there  Happy
Very interesting that your other pc give a similar change.
Looking fowards to trying this myself.

Hi,

I have been trying direct vs Phisolator occasionally going some time back. The Phisolator was best when I tried however these listening experiances were with an intermitent connection problem with my NOS's 10 cm usb link which was really impacting sq without my knowing at the time. The sort usb lead is fixed now.

Recently I have been looking very carefully at ground loops and transformer coupled mains noise at the dac and pc ends of the usb link (this work is being carried out on my x99 audio pc). The fixes in place make a very significant difference to sq at least in my system, they impact the strength and articulation of bass, high end sweetness, midrange tonal warmth and above all SPEED (the impact is very posertive). My guess is this has a lot to do with reducing noise impacting usb d+ d- signals which are themselves quite low level. I am midmway through measurements of ground currents and coupled mains noise but have had to travel this week so not fully done.

With the above as background I will give direct USB another try later this weekend and see how it sounds, based on past experiance I expect the Phisolator to be preferred but much has changed so it will be interesting to see.

Nick.

Hi Mani,
Is this with DAC and Audio PC both moved onto to the same mains / PE now ?

I saw a pair, when I went to pick up the Orello's. I was wondering if they were the same ones ?

I have to say they look very nice  Happy

I hope to hook up with an x99 with clock PC at my place next week...

I've never been called 'an x99 with clock PC' before Wink

Looking forward to coming over Nick... should be a very interesting day.

Mani.

Haha, yes looking forwards to seeing you  Happy

Hi Peter,

This definaly kicked off for me because of your posts  Happy.

At the time you started this thread, my X99 clock project was finished. It took close to 2 years and literally 100s++ of changes, the sound was really something very special but there was not much else I could think of to keep me busy on the x99 board so I was starting to look out for something new to try. Then you posted on the  Intel Scalable Processors and 601 PCH chipset. Our systems are very similar so I got straight away that you were really onto something. A look at the PCH 601 data sheet ( 3000 pages :-) ) really helped decide to do the build. Besides all of the very important for a music server archtecture features you mentioned in this thread, the 601 chipset clock system has changed from the x99. Its like someone in Intel thought "lets give those audio guys a helping hand"  Happy. On the face of it on paper back then and now listening to the built PC I think you are right in that much of the X99 clock benifit can already be heard in the 601 based build...... billiant !

Regards the sound quality, IMHO the 6130 build is very step from the Stealth II (which is quite a suprise given the excelant sound quality of the Stealth II). My clock bought a lot more to the table on an x99 system and now the 601 / 6130 takes a big step forward from there.

I hope to hook up with an x99 with clock PC at my place next week to do some direct comparisons (unfortunatly I used parts from my x99 in the 6130 build so I cannot play them back to back right now). The focus is not so much on might the 6130 be such a big step forwards. It just is. But on comparing the effect the clock has as I think there may be a little goodness to be got with the 6130 system but I want to be sure before I risk wrecking some expensive components  Shocked

Regarding the 601 / 6130 server build, yes its certaily different to a desktop PC, even now I have some instability that I have to sort out. I know how well rounded and complete your stealth builds are and stand by my comment that the Stealth III is going to be good value given its content and the SQ performance.

Definatly enjoying the music just now  grazy

Nick

Hi Nick,

So you received a Stealth III? This one would be the 2nd one I believe.

Michael

Michael,

No I dont have a stealth III. But felt it useful to comment on 6130 sound quality.

Also having been through a build and knowing what bespoke componemts and work Peter puts into the Stealth II, (but not of course the Stealth III) I genuinly think that the physical package and most importantly the music quality make the Stealth III great value.

KR,
Nick.

Hi,

I dont want to distract from Peters Mach III thread but I can offer some supporting comments on the sound of a 6130 16/32 core system.

Sound quality is EXCEPTIONALLY good, its an absolutly outstanding device for music replay. My old PC which was an x99 14/28 core with some modifications to its clock and power supply arrangements,  which set a very very high bar for SQ. To have the 6130 play so well in comparision is a major supprise.

The 6130 was not a straight forward build, as Peter says above server boards are certainly a new environemt, and it is expensive. I absolutely agree with what Peter says about sound quality here. Having been through a build, IMHO the Stealth III looks like very good value to me.

Regards,

Nick.

Hi Juan,

I have to tell myself ithe wait ts like going back getting up to drop the needle on  a new track or changing an album on vinyl, its sure a wait.

Interesting that you hear a difference too. 
I hear a lot of more detail with warmer more natural voices in particular.

Best regards,

Nick.
13  Ultimate Audio Playback / Playback Tweaks and Source related subjects / Network speed - sound quality on: April 28, 2018, 09:01:35 pm
Hi,

Network software driver settings make a big difference to sound quality. The context for trying the tweak that follows is an XX replay system that makes use of an ethernet network connection between a Music Server and Audio PC to pass music files and support remote desktop access to the Audio PC.   Sound will change I think with XX software playing in Attended Mode or Non Attended Mode despite the network being turned off in non-attended mode.

The tweak is to force the  ethernet connection speed between the two PC down from 1GB (which most systems will default to if left to auto negotiate ethernet speeds in control panel) to the lowest speed of 10Mb/s.

I set this up a few days ago with the thinking that the  Network Adaptor and its software drivers on the Audio PC generate masses of hardware interrupts (that influence sound) and the adaptors software driver will register different resources and possibly it and the adaptors hardware process requests at different speeds depending on the ethernet speed that is set up.

The tweak is quite simple to try.

On the Music Server PC in Control Panel > Device Manager > Network Adaptors double click the network adaptor that is used to connect to your Audio Server. In the Advanced tab go to the Speed and  Duplex property. It will probably be set to Auto Negotiate (in which case you are probably getting a 1Gb/s ethernet speed if both PC can support his). Change this to 10Mb/s Duplex (you can try 100Mb/s also) but 10MB is where the magic is here for sure.


(I am running a few other network related Advanced settings which may also add to this but I think the link speed alone will make a difference).

Sound quality is best summed up:

CLARITY and fine detail ! (in very natural and good way), Pace and PRESENCE improvments. I am really quite shocked by the difference here. And it influences sound in both XX Attended and Non-Attended modes although to differing degrees.

Be prepared to wait for your music to transfer from your Music Server to your Audio PC (the link in theory just got upto 100 times slower) so it takes longer for music to start but here is massively worth a few extra seconds wait  Happy

It may be that others are already doing this and I missed it, but give this a try and let me know what you make of it.

Regards,
Nick.

One foot note, Bass may be ever so slightly softer or perhaps everything else go so much better, or maybe is not really changes cannot make up my mind yet.
14  Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: 2.10 sound quality on: April 28, 2018, 03:45:02 pm
Haha... 2.10 Bass is back  Happy

Just a quick update on my ealier post on 2.09 vs 2.10 base.

I was sure I was hearing a large difference in 2.10 output and this was correct. However, 2.10 bass is fixed now and is sounding at least as good if not better the 2.09. I am REALLY pleased with the overall sound, now getting the supper sweet 2.10 mids and highs with epic dry powerfull bass the extends stongly down again in the low bass frequencies.

The fix to get 2.10 bass back was two things:

1 Bios settings - needed to set spread spectrum to "on" in bios (x99 mobo).
2 NOS1 - needed to tighten up board connections in my NOS1. This was my fault and shoul not apply to other people.

Overall now an sound is EPIC, low bass is back and now better than 2.09  Happy

Thank you all for comments and suggestions above in the post.

Regards,

Nick.
15  Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: 2.10 sound quality on: April 10, 2018, 03:38:17 pm
Robert hi,

My comments are not born out of being used to an old sound and not likeing a leaner more damped reproduction of the new. I will try to give more background.

Regarding the bass driver excursion observation, in my system this is very relevant. The reason for this is that Orelo speaker bass is generated by open baffled horns. These require relativly large cone excursions needed to reproduce low bass frequencies. They Orelos have a flat respone down to 17hz iirc, to deliver this resonse the dsp which drives the bass has dbs of signal lift into the drives in the sub 40hz region in order to move the speaker cone sufficently to produce the flat resonse. For Orelos a drop in cone excursion to minimal levels at low frequency means there is a significant drop in output.

I think your PL Audios subs may be enclosure or possibly reflex loaded meaning that its excursion can be much smaller relative to an open baffel system so I would expect quite a difference in low frequency cone excursion behavior between our systems.

I have not really provided the full system context for my comments. To explain, I have spent almost two years developing and tuning pc, dac and speaker modifications which I have not posted about. These really elevate sound quality to a very high level (this is in the context of the already high starting point of my phasure / db design system). With 2.09 the bass performance is very realistic in energy levels whilst staying well defined, damped and delineated. I do not measure room response but I would say response is good down to the 17hz roll off of the speakers. This means that kick drums and electronic bass sounds for instance go right down whilst retaining realistic energy levels and quality in my listening room which is quite large.

The issue is that in the last half octave 2.10 is just not doing this. I can try software settings again and see if these pull the sound back, but right now its somthing of a no brainer 2.09 excels in low bass, 2.10 is better in most other areas but if scale and PRaT are needed by the music I still find myself going for 2.09. Just hope there is a way to get the bass back to where it was with using 2.10. More work to do......

Regards,

Nick.
