The basics of PC audio

Some questions for you:

Assuming you have the PCU (in my case, a Mac Mini) near the stereo, with a USB DAC coming out of that into the preamp (or do you have it configured some other way?):

a) What does one do with the monitor--perhaps run an extra long cord and put it away from the system to keep the RF from feeding into the audio?

b) Can the CPU be placed far enough from the preamp to where RF from it won't affect the sound of the system?

c) What about using Apple AirPort Express and AirTunes and running a USB DAC out of that into the preamp; are there any advantages/disadvantages to that sonically vs. having the CPU feeding directly into the DAC?

d) Suppose you buy music from the iTunes store in MP3 form. Can it be converted to aiff or some other "lossless" format such that you'll wind up with a high quality file? Or does the fact that it was already converted to MP3 doom it to sonic mediocrity?

e) How quickly are USB DACs improving in quality? I don't want to buy a DAC and have it be obselete the next year.

I appreciate your answers.

Thanks,

Matt

Matt, there is no RFI unless you have really susceptable front end. It is best to connect the dac directly to the MAC. You cannot recover information that is in ACC so why convert it. Upsamplers and such suck the life out of music. Most AAC sound pretty good, not as good as Lossless but who cares. Sometimes you just need to listen and have fun and not get so tied up in the details.

As I see it the dacs at 44/16 will be here for a long time. The next logical conclusion will be lossless downloads. We are pretty far away from high definition PC audio as loading those files would be at least 4x the space.

Thanks
