Super stuff again lads !

Paul, great that you have the PSU back and can use your heavenly trimmer again. How does your wife feel about it ? ha ha

But special thanks on ideas about when the card is not seen. This will be the most helpful. Will proceed on it today.

And hey, no heavenly trimmer here. It's on viagra all the time you know. Fixed Value. Cool

Regards,
Peter

I just modded my paul pang card a little and ran into an odd situation.

What i at first did was connecting the secondaries of the hf trafo to the PCB x-tal and PCB gnd at the removed capacitors respectively.
The result: no card detected.

This got me thinking: the original capacitor on the secondary could be necessary in the end to block a dc component at the NEC chip side.

Reconnecting the capacitor made the card work again. So that makes me wonder how the DEXA clocks work. They must have some capacitive decoupling on the pcb to avoid this situation. Or maybe this only holds true for the way the pp usb3 card is working.
Nick, how did you connect you previous clock experiments clock signal to the usb chip?

Anyway, the sound has more bass and naturalness than I can rember. It is also a bit too laid back and soft for my taste. This could just be the clock difference thing here.
Unfortunately i have no heavenly trimmer available.

Now lets see what the one clock thing brings. Suggestions how to get this working with a minimum of effort are welcome. (Does the NOS1 usb oscillator also have a dc component?)

Regards,  Coen

Coen hi

Nick, how did you connect you previous clock experiments clock signal to the usb chip?

My DIY clock used capacitor decoupling on both output of the clock module in serise with the transformer primary coil and also on the secondary of the transformer on its output in serise before the signal connects to either the NOS PCB or the PCIE USB card.

I tried direct coupling of the clock module to the transformer primary and the transformer secondary to the PCB clock inputs but this resulted in a loss of signal amplitude and would not drive the USB PCIe card and NOS PCB IIRC.

Hope this helps,

Regards,

Nick.

Thanks Nick, this is helpfull!

The signal loss would be due to the dc component saturating the transformer core.

Next to providing galvanic isolation, which the capacitors allready can do if you would add one on the other leg, I think the benefit of the transformer is that it acts as a band pass filter. by its nature it removes the steepness of the signal. This leaves a signal with less unneccesary hf energy that would be detrimental to the sound.

LOL

Coen, aren't we getting crazy (by) now ?

I must say that I have applied similar elsewhere by means of lowering the (official) voltage. So if you are crazy I am the same. But careful now, because while my reaons were exactly the same (hey, we do get along, don't we ?) in your case there's theoretical jitter in order, while in my case it was unrelated to that. So Coen, keep in mind - we are on the track of "no jitter can be in order here" but from the other angles (stability - spreading peaks) we might be after all and actually it is my best bet at this moment.
Btw, spreading peaks sounds nice as a phenomenon, but that can be in control, while your idea here will spread too, but now out of control. So there is a didference.

So I am sure you see that flattening signal tops is the worst for jitter and it should be the other way around, and I'm just saying it because it may have skipped your (net) consideration.

But once again : great stuff in itself.

I am glad I am not the only one with the most easy appliances not working at all. So I did not tell it yet, but the most basic connection in my special situation already does not work (clocks normally running on all sides). So I am as far as no NOS1 to be seen anywhere.

You guys should see what's all done to deteriorate further and further to come to the conclusion in the end that the base "configuration" even doesn't work.
The only thing what keeps on working is that my PC keeps on booting. Ok, once out of two times, so that is progressing also.

swoon


PS: We just moved the lot out of the listening room, Waiting for you now Coen. That's more easy. Too many variables here at this moment, while I apperantly seem to think that all will work but maybe one, while it is the other way around and I will not know which one.

Coen hi,

I am not aware of the spec. of the tranformer used by the Paul pang card so difficult to comment there but concentrating for a moment on my DIY clocks build and the Dexa clocks. The main application of the output transformer used in both of these is for ethernet network transceivers signal isolation, bandwidth is rated >100Mhz. I guess to preserve the signal waveform the transformers effective maximum pass band will be much higher than this.

What has struck me with the experiments on USB clocks so far is how much more that jitter reduction seems to impact on sound quality than clock RF impacts sound as HF components of square clock waveforms increase.

Given this my thinking is that bandwidth limiting the clock waveform might improve general electrical noise but is likely to also impact phase performance which in turn could have a big impact on sound.

Im still very keen on clock transformer decoupling as it is appears to take ground loops on the clock connection out of the picture which can otherwise be a big problem for sound quality. But generally it think high bandwidth passive components on the out put of the clock may be the best way to go.

Kind regards,

Nick.

Quick question :

Can anyone (or everyone) describe what happened to the sound when Paul Pang's card was used instead of a normal NEC based USB3 card ?

I'm into the 5th track of "some" setup and ready to post about something strange and that maybe I found something ...

Mmmm  as it happens I have one of Mani's NOS1's here (totally standard no mods) so I can compare it with my modified NOS1 with Dexa's. I can try any combination (1 Dexa, 2 Dexa's, std NOS1, modified NOS1 etc) except I do not have a standard Pcie USB3 card - both mine have been hacked so they no longer have crystals in them one of them is being clocked by a Dexa.

So for various reasons the only tests I can do are against mobo USB2/3 which I can turn on.

Is that any use to you Peter?

The only other thing is I have to re tune my ears because I have been listening to a number of combinations and I am starting to show the first signs of madness (OK maybe not for the first time.......)

Oh and of course I have a Paul Pang card in and working...

Cheers

Paul

I have not done the comparison with XXHE/NOS1, but when I did it with my previous dac and computer setup the Pang card brought better resolution across the highs and low but most importantly it brought a more balanced presentation i.e. there was no bloated bass or shrieking treble..just balance, and smoothness.  But as I said earlier, that was with my previous dac and computer.

OK using Mani's standard NOS1 I have been listening with it connected to a mobo USB2 port. Both USB2 & 3 on the mobo switched on. I guess there is no need to describe what I hear because most NOS1 users out there should be familiar with the SQ.

Next I switched over to the Paul Pang card - there is a clear difference in sound quality. The sound becomes "fuller" less thin definitely a more "analogue" sound. Perhaps "Lush" would be a way to describe it and at first listening I would have said that it was tonally better - but now having heard the Dexa USB I am not so sure maybe it just sounds "fuller".

However, with the benefit of now having listened to the Dexa clocked USB link it is clear that the Paul Pang card does not improve on the clarity of the sound. But it certainly changes it.

Hope that helps

Quick question :

Can anyone (or everyone) describe what happened to the sound when Paul Pang's card was used instead of a normal NEC based USB3 card ?

I'm into the 5th track of "some" setup and ready to post about something strange and that maybe I found something ...

Peter


With the standard pp card I posted before that I felt it was delicate and natural sounding, but with less drive, less highs and especially less bass.

That is compared to my standard oem usb3 pcie card (earlier version of the NEC chip with onboard switching regulators for the chip and 5V). Reversely this sounds more loose and melodious, together with more realistic highs and dynamics.

Now with the little modification (secondary grounded near NEC chip instead of clockboard), I concur with Paul. i have to add that the sound is still a bit less dynamic (smaller?) and it seems more tilted to the right channel. The latter could be or is a frequency balance left-right thing.

Is this the kind of report that is addressing your question?

Next I plan to do some psu connection experiments, before taking the plunge to a one-clock setup.

Regards, Coen

A lttle update:

There is a significant difference in sound between the two USB ports. One (furthest from the mobo that I use normally) sounds round and a little thick and the other sharp and a little restless.

Furthermore I used a MOLEX to SATA power adapter cable to harvest the 5V and Ground (red and black wire) and soldered them directly to the clockboard supply, leaving the PP wires in place for the USB 5V.

Now this little change immediately sounded like an improvement: more looseness, natural detail and melody. Though this is a little hasty conclusion, I will give it some time and come back later wheter I still think it is an improvement.

Hey, thank you all (three). So now it is my task to make something out of that. Haha.

My own reference : Standard MoBo USB3 plus one night of listening through some NEC card the other day where I didn't really notice anything for differences. Maybe there was, but I wasn't looking for something and at least nothing occurred. No 5V.

But now last night ...

I used the other card I have (22 euros or so and with 4 USB3 connections) and thought some hell had broken loose. Well, at least in my mind. To start at the end :
At some stage I grabbed the SPL meter to see what I actually had been setting for volume, because I saw I started out for some album at -24dB in XXHighEnd which already looked fairly high to me, while I had been Alt-u-ing so many times that something had to be going on. I had been playing at 94-96dB for hours.
At passing the partner in crime here when walking with the SPL meter towards the speakers I heard her say "isn't that a bit on the harsh side maybe ?". -> No no, but I think it is loud (at that time only recally my Alt-u finger excersizes). "No, that is not loud, I think it is too harsh".

After this she told me to be totally tired because of the music and I - by that time - could explain it as "too much drive". And well, "drive" has never ever been a parameter for me. It exists, but it never occurred to me, and this is the first post I spoke about it in this forum.


Pumping. Not being able to catch up with your own breathing.


So how surprised was I to see Coen writing about "drive". He may have written about it more often and I just read it without notice, but d*mn, what important can this be. Well, once you are able to translate it to this "function" after hours of thinking what the heck I was actually listening to for changes. So, now back to the beginning of last night :

The very first (work of seconds) thing I notice (a.), is this really crazy emhpasis on a frequency which indiretly I dedicate to cymbals showing their underlaying main vibration. Say the lowest frequency they can express (all sh*t on top of that).
With the hope I am able to repeat all in the same chronological sequence I noticed things :

b. where is my fine bass (next 10 seconds);
c. finally that stupid delicacy is out (!) (1 minute);
d. What the h*ll is happing with all that rattle I hear and never was there by any degree ?;
e. where the heck is that frequency that is so profound (almost throughout the first 2 hours);
f. This is not about frequency ? it is on/off (see d.).
g. How can such a most profound change not cause a flavor in all ? I'm quite sure it does NOT;
h. This can't be right; I must be playing crazy loud by now. Nobody complains either ?
i. Sh*t mon, I am moving body parts which otherwise won't.
j. Why is all swinging so much. C'mon, this is no swinging music !
k. 96dBSPL ?? what the f*ck ?! and now someone says "maybe harsh" ??
l. So where is my bass; put that to the test. Put on a most profound.

It was actually l. when I finally dedicated the whole thing happening as DRIVE. How ?

Well, that super bass was still there. But it hadn't grown with teh SPL of the remainder - or something. It now occurred to me that there was super (can't find a "higher" level word for it at this moment) BALANCE.
Can balance imply drive ? never mind for now.

Seconds before I found "drive" I was sure it was about speed. Sheer racing speed, but at frequencies I again could not find. For sure not in the highest frequencies, which seemed to have completely overwhelmed by what was now happening under there. My bass test - same story actually; it is just overwhelmed. Still there and as good (felt the woofers many times - still feels the same), but all overwhelmed with where the real music plays. And I don't know where that is because it is not about frequencies. It is about on/off.

It seems to be the reverse effect of better resolution which I now tend to call "separation". Mind you, at the technical level. So, any On/Off shows as on/of while before it was a grey On. Not filled by injected higher frequencies ? (this one I make up right on the spot now).
How Leonard Cohen starts to more sound like him instead of Freddy Mercury. That kind of thing, but now in everything.

Yesterday I had been dying to try so many other albums, rock as a first, but I couldn't let go of whatever was playing and played because of again other "tests" first.
It is the biggest change I ever heard (which made me sort of post about it after being into a fifth track only, which is NOT like me at all).

But is this (topic) about SQ, or is it actually about something else ? Let's put that in a next post.

So, finally such a shouting post from my hand, on a subject normally a few others shout as loud as they can. I tried to stay away from "all for the better !!", but it is obvious that I can't. And maybe it is not. At this moment I don't care much. But I do care about is :

How the f*ck can sound change so much (and in my view at this moment even for the better) just because of touching a few USB interfaces. Hey, I like to be recognized as the one now with the largest change ever. But *did* I achieve a largest change ever, or has Nick's or Paul's change been in the same leage ? It can't. It can't because I see no description which even closely resembles mine. In fact they go the complete different direction. And I STILL don't agree with what's described; did you read my "stupid delicacy? That.

Sure, we like a delicate sound opposed to "digital". We like it to be palpable. We are pussies.
So PeterSt says we must like roughness or something ?

No. But what PeterSt likes to achieve is that somehow - without listening to eachother's systems - we can find the direction to head for. And when someone is glad that he now "can play" 6dB more soft while the other is the most glad that he plays at 10dB more loud without notice, something HAS to be quite wrong were it about consensus.
Agreed ?

But this is how I found it important to let the few of you express about your changes compared to standard MoBo connections and how I possibly could make something of *that*. But all so much depends on how we express about it. Like my stupid technical lists may tell nothing to you and "better resolution" tells nothing to me. That is, until a few combined expressions start to match.

Can I use Coen's ?

And shall we now finally tell what actually changed in my system to let it sound like that ? then at least you understand why I asked you the question in the first place :

Because of my other little project (one-clock) I via-via-via found that this other (untweaked) USB3 board did not want to work without 5V connected. Stupid little thing.
So for startes, that's the change. Or at least it seems a major one; I have one card perfectly working without the 5V where I noticed no difference (and didn't pay attention) and I have this other needing the 5V and I dropped on all floors from all chairs (and didn't like to pay attention BUT tried it explicitly because ...);

By cheer accident - and because of this other one-clock little project - I found that ONLY after the install of the formal NEC drivers because it didn't want to work - ... that right after the driver install there was a "power surge" balloon in the right corner. This happened with and without NOS1 connected, and I couln't understand. Still not BTW. Without the attempt to install this driver I would never have seen it, but while the PC recognized it happily without complaints, no NOS1 wanted to connect to it. And no way I thought that this card suddenly would need the 5V because I think I saw nobody write about any such cards needing it. And my own other of course does not. Only Mr. Pang's and that is dedicated to drive the oscillator. Maybe.

So this is how I tried to pose the question - actually to find out about similar changes to the sound, hoping to proove that all is about this 5V and nothing about any Paul Pang.

At least - and in this stage - we must seriously think about (and of course I am repeating myself for the xth time) WHAT actually implies the differences. A better clock in general, a more stable one etc. which needs so much reasoning, many more options, or the sheer randomness of injected noise, or removed noise if you want.

So, what I get from Paul's (and in the end Nick's) description is at least similat to what I perceive after inserting such a 5V fed card. So allow me, I for now just dedicate it to the 5V thing (don't know what it will lead to). Thus, by replacing *that* with something else like Dexa, the roughness disappears and all becomes a perceived silky etc. Too bad that this silky can be too much of it in my view and that more bass never has been good in my view, but what it is about is the similar description which I can easily call roughness (note : all for the better because *here* it seems to express as better separation on whatever micro level).

So believe it or not, I agree with Paul's description; happens the same here, though not with a Pang card. 5V yes.

This is how we need to look at Coen's description(s) because they far more resemble what I am saying. This is not all that easy to see, but here it is :

Quote
With the standard pp card I posted before that I felt it was delicate and natural sounding, but with less drive, less highs and especially less bass.

That is compared to my standard oem usb3 pcie card (earlier version of the NEC chip with onboard switching regulators for the chip and 5V). Reversely this sounds more loose and melodious, together with more realistic highs and dynamics.

Aha ! So Coen too manged to get hold of a card which needs 5V. Well, that is what I like to take from this quote (Coen ?).
Might it help, my card is a Silverstone - can look at the Chip type when needed.

Further down the line I see Coen talk about Drive which was never in my mind, but which I made up yesterday and I never looked in the forum again. Coincidence ?


Actually this is to be it for now. I know, my way long story may look like not much being to the point, but only when we start to recognize eachother's descriptions and hunches and environment (changes !) we might get to something final. For me Coen achieves the similar sound and liking of the various aspects as I do. This tells nothing, but of course I regard it important when it resembles my thang. Paul's and Nick's go the exact other direction. Can be as good, but won't sound like I like it. Important ? h*ll yes, because we like to achieve reality. And like I was happy two days ago, and seem to be more happy todat with a 180 degree different sound, what IS the sound to be ?
And we try this through written words ? Quite a task.


May it help, this is now my sound by more normal wording :

Any top layer - no matter silky and refined, totally gone. But I don't know and knew what to do with it anyway, because it could only disturb because too profound (masks reality of cymbals).

Power power power. Yes, drive. But also into the rythm (ok, must try Grace Jones now). Brought forward through detail in all areas - hard to define. I can imagine to find new washboards in upcoming albums to play, while no washboard has been in there previously. That kind of thing.

What puzzles and intrigues is why (read how) it is possible that the detail/separation (estimated at maybe 50ms of On/Off separation) and which is the most sharply boundaried, does not show any single harshness at all. This, as the lead in to rattling cymbals where no rattling cymbal has gone before (blame Spock). This, along with the higher pitched more bell like coming from it, generally dedicated as "more music". So that area (think 1000 - 2000Hz) has become super profound, is super dangerous in the mean time, but doesn't disturb at all.

Yes, no bass either. But still still there. It did not bother me by even one second; only the puzzling about how they could have gond did.
This is a dangerous one for anyone judging "wrong ! because no bass !". I can very well be wrong, but focus on the better coherence and how the overwhelming of the real music could be for the better after all;
I speak often about "so normal". In this case it suddenly was "so normal" that this profound bass was not there (but mind my speakers). That bass has been so mighty interesting, plays main melodies etc., but I only now wonder how normal that is.

With the latter in mind : all is the opposite of "thin". Strangely though, this emerges by the removing of the silkyness as I think a first, to next being filled out again by the roughness which is round (and no single way I can perceive it as distortion).

The whole top layer (but think above 1000Hz) has become a live concert instead of pussy audio homo desires. Yes, strange wording, maybe not meant to say what it looks like, but the opposite of live music that would be. Also (but I am trying to dig that out afterwards) : smashing cymbals like never before, without the nasty top end of them being able to hurt.


Ok, too long again. But thinking about electrical merit (just hunches) :

Earlier, noise implies false HF to be there and it expresses (or can do that) as a HF top layer which though silky does not match the underlaying implied (!) foundation. In the mean time this same noise is actually everywhere, and fills "separation gaps" unauthorized.

Thinking about more high (volume) peaks at this now not anynore flattened "mid" (??) frequencies, this is THUS about flatting not happening anymore just the same. So, not only gaps re-emerging, but also flattening less happening. I *think* that both should lead to LESS noise (not more, which as you know is so often my idea about changes).

How ?
Maybe others can get wild here. The NOS1 does not require "power" as such. Still, maybe that 5V supply provies more of it. Oh hey, but what about the SNR in there ? Say more signal same noise ? So, better signal ? If so, where is that utilized ? Fewer USB retransmissions (with following goodies) ?

Guys ... IF it is correct that this is for the better ! So I am posing that, but I know I can't do that in a few hours. But what I try to do is find the WHY of the changes and it would be so much comfortable when we'd knew for a fact that the changes are for the better to begin with.

Blahblahblahblah. But trying.
