Hum... Why not precise that the numbers start from the nearest button when you face the NOS1 By "down", I meant that to activate something, you have to press the button down... Different perceptions I guess... Alain Edit: Ah... Sorry Peter, now I realize where the "down" was out of place.

Hi Pedal, Yes it is correclty set for 705 and 768khz potentially Alain Edit: from right (in the picture) to left: the second is turning the DAC ON and the leftmost is for the 705-768khz when as you have it, or for "Stereo reduced" when down...

So Alain, here we go ...
(Explanations)
Hey Alain, was this something for a suitable answer ? Best regards and thanks for the 100% justified good questions and pose, Peter
Hi Peter, Wow, that is more than the customer asked , but it is a lot clearer now ! I understand between noise that is inherent and noise that is "inserted" and/or "added" I am not aware of any manufacturer taking the time to explain like you do ! And I also liked the "Yo" and "Hey" scenario you created to explain how things happen; it really is a nice story. I read it with a lot of fun I even caught the "Thanks Alain" from the picture of that lady over a... "Tank" of water As for Mani, yes you summarized it very well too Another rainy day here, but wil what I learned, I feel emotionaly isolated from these grey noisy clouds I can now "upsample" myself over them Regards, Alain

Hi Joachim, I know where you are coming from Of course, "absolute" cannot be, but I was relating this to Mani's example (or metaphor) to illustrate Peter's breakthrough... While vibrations is of concern (as Peter has showed), electrical noise is and will always be a concern, up to a certain extent... And a PC is full of noise than can transmit through any cable and through other conductive material... Alain

Hi Mani, I think I understand And there the dreaded "But ?" intervenes Of course, the better I manage to isolate from the vibrations, the better the results. I could even put my device in another room where the vibrations will be attenuated, but vibrations are from everywhere, even if they don't come directly from the speakers ? We tend to think (correctly) that vibrations will come from our speakers and from what I have read there will be a lot of them coming from the marvelous pair of speakers you (I hope soon) will receive, but... There are still other vibrations that will affect the wall, the floor (inaudible, but measurable) and all that sits or is ankored somewhere. The analogy with electricity could be that though the work done to eliminate as much vibrations as possible, there will still be some left. I know we know that it will be reduced to a point not attained up to now, but still there is potential ? Let's say that I have a capacitor that is "singing" (I am really not sure of this example) or there is a high frequency in the AC because of a switching power supply... ? In the PC, a measuring device would go crazy (I guess), so since electricity is fluctuating due to different forms of current draws (that we have been fighting against for years now), how does this translate in the link between our two devices ? This link is a path and what we call the "signal" and what could be called the "efforts" done by all the components in the PC to generate, process and send this signal... English is not my first language, so sorry if I sound strange with my questions... Ultimately there is one thing I believe. We will hear the results of Peter's hard work and this is high "gastronomy" I just hope that my NOS1 will not get sick in the transit Regards, Alain Edit: If I am right, the best way to do things (apart from what this will bring) is to "eliminate" the noise at the source... Well, this is how I understood what needs to be done in hi-fi... At other times, the turntable was the "source", but now with all this loudness war (compression, clipping), we know that the studio manipulation is at the "source"... So if the source is bad, the rest will suffer to a certain level... Maybe I lack many details in my questions and attempts to answer them (in my mind), but since "the results will be the one from the weakest link" and the PC would be that weakest link (as it probably always have been)... So my take would be "Well, if I persist in using Minimize OS, go unattended, use the non persistent network only for loading music, it should not be harmful no ?"... Lots of questions I suppose some tweaks will not be effective anymore, but maybe a few left will still be in order ?

Hi Peter, Once my surprise has gotten to a level I can manage (...), there are still some questions for me to be answered. You mentionned that as a hobby, most tweaks would not work anymore and in a sense, this is a dream come true for those who prefer a "plug it and forget it". In a way, for a guy like me, there are some aspects of this that I could not easily grasp. Add to this that SQ will increase again and you will not only make my day, but my months, my years... And my ears But some notions have escaped me (this is an understatement) in the process. I have thought that noise (born from all situations that occur inside a PC) was taking any path that would be easy for it to take. So, since the PC is connected to the NOS1 with a USB cable, the data line would already be carrying noise that has nothing to do with the signal itself. Even if someone was using an optical device (like Adnaco), the noise "within" the signal would also go to the dac no ? Following this logic (probably from my confused understanding), it made sense to reduce all that could generate this noise in a PC (Minimize OS, stop many services, underclock the CPU, play unattended, avoid networking, even use a linear PSU, etc...). If I recall, there is inherent noise related to USB protocol and if there is also noise with the signal path, how does your modifications be stopping this from altering the dac ? I could of course tell myself that even if I don't understand, the results will be there, but it would help me if I just could eliminate from my mind a part of these questions that have been there for years. Or at least, I will stop having erroneous perceptions about the noise running everywhere, taking any path it can... Regards, Alain

Hi Peter, Can you add me to your list ? I suppose I could send it when you will notify me with some advance, since there will be the transportation time... I am excited, but for the time being, I will put some money aside Will you put all the info needed (address and all) somewhere ? And finally (...) What is your advice about leaving the NOS1 floating on liquid, so it will better endure the shocks while being returned to you ? And if you can explain how to electrically isolate ourself from certain emotions, it would be a bonus Regards, Alain

Ultimate Audio Playback / XXHighEnd Support / Re: XXHighEnd Eliminated ?

on: May 12, 2014, 12:58:14 pm

Peter, I know all that this software had cost you in time to make and improve our music to such a level that it is unbeaten. But if it always had been your aim to eliminate XXHighEnd, then this is a wonderful achievement I will wait for what's next (the PSU change) to see what are the options... But of course, there are still features that will be necessary to have to bring the right signals that the NOS1 need to work properly. I suppose some of them will now be included in the driver, but anyway, there will always be a need for a software to start from. Ad this raises questions like the isolation of the USB controller card from the PC chassis (plus the black wire that is detached in the NOS1)... Plus a few other things I am not thinking at the moment... We can either think of things in a sad way or be happy with the results of your discoveries and hard work. I prefer to choose the most positive direction All should be easier to grasp when we will be faced with it in our homes Alain

Thanks for the reply Peter. I, like Mani, often talk about you as a "genius", some other times like my "guru". This, all in good spirit of course. And yes, USB plus the elimination of the final device... But one thing at a time right ? The achievement you have again reached is something to have a couple of beers about ! As for the adjustements that would be obsolete (I still have some troubles with this, but it is not intended on the fact it will "cut" in the hobby), if "that was good for this", and "this was good for that", there lie some explanations that may be answered someday... I would not remove all of them now, well not the "Minimize OS" ? Unless this brings too much assle with this breakthrough of yours... But of course, this is your "child", and it has grown a lot since Kind regards, Alain

Peter,
I will not pretend I understand everything, but I never really thought that vibrations would affect the NOS1 like this (and, I guess, other components). Wow !
Am I ok to interpret that at these levels (such low level voltage), anything in the power will also affect jitter ? And that new power supply (the thread that leads to this one) will improve on these artifacts ?
Maybe I am not using the right terms (like "artifacts"), but I will need to re-read this a few times...
This isolation that you brought (floating on water) is not so funny anymore...
Finally, when you mention that XXHE will not affect the sound anymore, you mean that the dials and other adjustments will no more be needed ? Provided that the power supply is upgraded and the isolation taken care of ?
Again, thanks for sharing this !!!!! It's a major eye opener !
Regards,
Alain
