De IMdisk drives are not external they are in RAM.
The corresponding files that store the data when the computer is off (and RAM empty) are most likely on an external harddrive.
Yes, you are right, I should have expressed the previous post this way: "Iīm not sure if I understand it well. In one external drive you have: - (C:) for OS and also you have: - IMDisk (a:) for XXHighEnd and XXData - IMDisk (b:) for Playback Drive Is it correct?". To tell you the truth Coen, I donīt understand that configuration, maybe someone could explain it in an easy way. Best regards, Juan |

Yes, IMDisk for XXHighEnd and Playback Drive. The drive for XXHighend is needed for technical reasons.
These reasons are speed related and from this I should say that everybody will have a good chance for better SQ just because of this alone. So, try it.
Put XXHighEnd in a RAMDisk (drive), and of course start it from there. XXData can stay where it is, but I copy that to the RAMDisk as well (only because I feel that this is a consistent way of working - nothing else). And remember, as a: (and b:) drive, FWIW (see posts about this elsewhere for context).
Peter
Peter- Iīm not sure if I understand it well. In one external drive you have: - (C:) for OS - IMDisk (a:) for XXHighEnd and XXData - IMDisk (b:) for Playback Drive Is it correct? More questions: How do you connect that external drive? (Coen question) Why do you talk also about RAMDisk?, isnīt it a choice between IMDisk or RAMDisk? (I know that IMDisk has more capacity).

I wonder if you (Iīm talking to you all) shutdown your Music Pc every night. Some time ago I kept it running all the time, mostly to get the NOS1 warm but now I shut it down at the end of the day. I think that Peter said something about it today and if I understood it well, he keeps the pc running all the time. Is there any real advantage to keep it ON continuously?. We all know that in general it is recommended to have the system ON all the time (except valves of course).

I had the same problem when I installed 09-z9 for the first time but I ran Ccleaner and restarted a few times and never saw the problem again. I donīt remember well if it was after or before I installed the last 9b version, I think before, but anyway I havenīt had that problem again.

There are so many factors that can explain the different situations when sound is either low or loud... I can only express that depending on the ambient noise and the fact that our hearing will be less sensitive to high frequencies at low volume (and other factors), it would be normal that there would be a loss of details (I think).
Alain
Yes Alain, you are right, there are many factors that influence the perception of sound, some of them are external and some internal. Maybe the perceived distortion at low level volume could have to do with the loss of detail, perhaps with the loss of data but at high volume level, I mean higher of a certain level, the distortion could have to do mostly with the room acoustics.

Iīm out of home for a few days and I canīt experiment at this moment with super high volume, but I remember the other day that the sound was not as good as other times and I keep listening and maybe around 3 to 4 hours later the sound was great again. If this has something to do with warming up the OS or not I donīt know but I related this to warming up the system because I turn it off in the night.
About the volume level, as I said before, there is a volume that for me is the perfect one, I could define that perfect level as the one where I perceive ALL the sounds in the best possible way, and if I go up from this level the distortion is evident. At lower volumes of this perfect level the sound is good but I canīt find all the sounds (are they lost?)
Best regards,
Juan

Ultimate Audio Playback / Phasure NOS1 DAC / Re: Price NOS1 goes up + Upgrade

...the cost of the upgrade (today 100 euros)....Now, 16 months later, people may be up to it with the prospect of again really really better sound (more genuine bass, again more accurate highs). So please go ahead with it if you like.
Peter
If there is a waiting list please sign me for the upgrade. Best regards, Juan |

What I myself will not be careful about is vibrations in the PC. I mean, *that* I'd call nonsense. But please, only by the sheer fact of not being able to reason out how that could matter.
Peter
Peter, I understand your point of view but the fact that we are not able to reason out how that could matter does not contradict the experience that shows that when we eliminate the vibrations the sound is clearer and more defined. Maybe at some point we also give importance to the vibrations in the Music Pc if we consider it as a transport or source component as we also pay attention to the vibrations, at least in the High-End world, to any other component of the system. On this site are manufactured parts to prevent vibration in the electronic components and components of PCs and also is possible to read some interesting articles about vibrations: Parts: http://www.vibrationmounts.com/NewXGel.htmTechnical information: "A good vibration isolation system is reducing vibration transmission through structures and thus, radiation of these vibration into air, thereby reducing noise." http://www.vibrationmounts.com/V100/V100Cat.htm#TechRegards, Juan |

I would be very careful about statements that more memory etc. does not matter. I mean, since everything matters ...
All other electrical (!) noise implying stuff in my view *does* matter. And this includes too much high-demanding memory. Did you ever notice how hot this gets ? Heat itself already implies thermal noise, but the current "needed" to make it that hot for sure does. How that creeps into our DACs is another matter, but let's say it has been sufficiently proven it does (XXHE dials and such).
Peter
Ok, now I know more about it, thanks Peter. Iīm going to remove two of the six 4Gb modules and see if I can tell some SQ improvement. Regards, Juan |

The things (like 32 gigs of memory) may be overkill, but is it going to hurt? Are there items that are detrimental in my list above? Maybe the huge PSU is overkill, but it has some of the best specs around? It is the one thing I changed out already and I think it may sound better than the old PSU, or has done no harm.
I have 24Gb of memory and a PSU of 750W in my Music PC. This may be excessive for the purpose of the Music PC but I think it wonīt alter for the worse the SQ, unless more memory or more power in the PSU produce more interference or more vibrations, and that does not seem to be the case if we look at the specifications of your 1200W PSU. About the memory could be a waste if you (or me) have more than those 16Gb but I think it wonīt hurt. Regards, Juan |

On the volume thing ...
What I reasoned out those 3 years ago is that the level is to be of some consistency when you want to perceive the real thing. So, not too loud and also not too soft. What I by accident found is that it just needs to be at real levels...
...As said, I never thought of that anymore, nor did I feel the urge to tune in this sort of reality level, but today with W8 this is so again. And no, I didn't start to think about this because Juan said so. I found that myself which should mean ...
Well, that only if just two persons make the notice, there should be some truth in it. Thus, not for W8 best settings in general, but because there could be truth in our brains liking the real thing the best, which includes the level of sounds we hear around us.(highlighting is mine:Juan). Next it should perhaps say that W8 as how it is now is "a very best" because it again urges for this setting, hence it allows us to perceive this realism.
Peter
Very interesting Peter, I think you've managed to summarize in a few sentences what could be a psycho-acoustic treatise  Strongly agree. Best regards, Juan |
