There is simply no mechanism that would change the data if your CPU is 70% idle instead of 90%. Or do you loose money when you make a bank transaction and the database server is not idling at 90% or more ?
Haven't you heard about the jitter on Wall Street? 🙂
Aah! Science and reason versus irrational feeling... I get it. You appreciate music via the medium of diagrams and scientific papers not by your senses and emotions ! I suppose there is a scientific reason why you like one song over another and you can explain it with the help of spectral charts and medical papers on neuro science... LOL :-D

That reminds me... why do you even need something like fidelizer or jriver app for music playback on windows? Answer that question to its logical and scientific conclusion and you will know who is the fool here :-D

No, we just enjoy our irrational feelings without being deluded into believing they convey the absolute truth.
Enjoying music is not the same thing as designing a sound reproduction system. I think the failure to realize that is a pretty fundamental fallacy.

You tell me - I don't need them.

Thats a good example of the notorious western mind, strait jacketed in the world or aristotelian binary logic. Either this or that, never a point in a continum that may be in between. You beleive you are not being swayed by an absolute claim (which I never made) while staying absolutely and unconsciously rooted in the opposite camp like it is indeed the only truth. Classic example of when you point a finger at someone, three other fingers point back at you... :-D
First you need to learn to distinguish a truth claim from the absolute truth. Then understand that what you believe to be true is only a truth claim not absolute. Once you are there, we can talk.

Aah... like the painter who cannot see... so your best audio designer is one who listens without feeling and emotion and never tweaks his designs accordingly because that would deviate from the state of perfect specs and measurements... I get it!

"Feelings and emotions" come from the musicians not the playback equipment. The waiter is not supposed to add spices to the meal the cook has prepared.

Yes, that's me. If I wanted to change that, there are enough coffee shops here in Amsterdam...

For some people, even the name of the restaurant is more important than the taste of the food...

Unfortunately you are wrong.
HFT relies upon extremely fast bandwidth and CPU processing - including server load and jitter - to front-run the market and make more money than the person who has a CPU that is less idle. Millionths of a second count. Noise floor (that's jitter and CPU load) counts. Other apps running at the same time count.
Or is the content of Gobbles posts degraded because of the server load and in reality he did write something sensible ?

Yes, someone is clearly relying on pseudoscientific gobbledygook to make money.
I tried cPlay, but it causes my PC to hang and then crash.
So, I suppose, it is doing its job perhaps too well.
For audio a dedicated audio server on a laptop, used can be found for $100USD, set up as an audio appliance and used only for music would be better suited to such an app.
What I do is set up a profile, Windows XP only feature, that strips out all services but 3 and makes the OS and PC into an audio appliance. The same can be done with more work on any Linux flavour by kernel cusomisation.

Or you could just enjoy linux as it is - it won't make any difference to the sound as long as you don't totally overload your poor little computer...
I do not want to start any win-lin flamewar, but to achieve the reduction of services in linux is trivial - do not install them at all in the first place.
E.g. installing debian netinstall takes just a few minutes + installing the ssh, mpd packages (with automatically selected dependencies) and be done. Of course setting up the complete solution takes much more but not many more processes will be needed.
I find such approach much easier and logical than the trial and error way of removing the "hopefully unneeded" windows services.
There is no need to hack the kernel - it will load only modules needed for the hardware (incl. usb audio on demand).
As of the number of processes reported by windows - there are running threads in kernel drivers too, I do not know if these are reported in the task manager window. They can easily take more CPU than the user-space services.

I compared (quick and dirty, no blind listening etc) Win7 and Ubuntu 12.04 sound without any tweaks-optimizations with cheap USB soundcard, but good and clean system.
Ubuntu's sound had clear dirt in it: it was furry. W was clean. It's not jitter, I know what that is and does. U was as-it-is, without Jack. The difference was so clear I stopped thinking about Linux.

I'd love to see your ABX logs...
but good and clean system.
Ubuntu just like any linux desktop distro is not a "clean system" in terms of bitperfect audio playback. Very likely your playback chain involved resampling in pulseaudio. Jack has nothing to do with it, its use for "audiophile" playback is plain nonsense proposed by people without any knowledge of linux audio.
I talked about barebone linux installation of debian netinstall which is incomparable with full-blown ubuntu desktop.
PS: Apart of the ABX argument, of course...

This could be so many things:
-The codec Ubuntu uses
-how it is implemented
-whether it is given high, multithread, or low priority
-the drivers for sound cards, usb devices, dac's and so on
-other software in the Ubuntu stack causing OS read/writes and jitter/bus noise
-and on and on and on
Makes one long for the days of direct realtime 1:1 15ips tape transfers.

None of the above. As phofman said, the most likely culprit is resampling in PulseAudio, which is easy enough to get around by simply telling your audio app to use direct hardware output. Many Linux audio apps have this option available in the configuration options/preferences.
Just as with Windows, if you simply do a fresh install, and then install some player app and click "play", you cannot expect bit-perfect playback.
I also agree that Ubuntu is not the best choice for this type of comparison. When people say or write the word "Linux" it can mean so many things that it virtually means nothing at all. Nevertheless, it is and always will be my #1 choice for audio purposes.
