    I read an article a few months back (can't remember where) on MP3 sampling rates. The article indicated that professional audio technicians listening to mp3s on professional gear could not tell the difference between compressed mp3s and the uncompressed originals at sample rates at or about 192kbps.

    I did about a days worth of research at the time, in order to determine the sample rate that I would use when archiving my music collection. Although I cannot remember where the source is, I am fairly confident that my search was rather thorough. Sorry to be such a lame *** and not site my references.

    Uh err... I sheepishly take it all back. It was 256kbps. Dang there goes my credibility.

    I don't think it's software related either...

    EPIA on board sound blows chunks...I tried it and it has very poor low end response...I got a M-audio usb sound device and it is much better...not quite audigy quallity but close enough...

    Thanks for the replies, guys. All input gratefully received.

    osirisdon - just to clarify, the "my stereo is as good as a set of monitors" was more to make sure you guys didn't assume I was Mr "I've got a sub the size of a house and so my stereo sounds great" It's a damned fine system, but it ain't that good

    That said, when using the head unit's CD player, or tuner, the quality is all there. The main reason for my concern is that even if I take one of the mp3 albums and use Nero to convert it back into an audio CD, and play that on the CD player, it sounds far better than the PC version.

    Will dig out a CD-ROM drive and play a CD through the PC, to see if that's any better. After all, that will use direct audio, rather than the sound card's processor. If that's better, I can safely assume the problem's with the PC or the software.

    I am inclined to think it's the sound card though - hell - anything built-on ain't going to be much cop on a 100 board Got a 24bit sound card coming, on loan, in a day or two. Hopefully, that'll make the difference I'm after.

    Keep up the good work guys - all comments appreciated

    A reply for you...

    I use the EPIA M9000.... I used the on-board sound card for aboue 3 days. It sounded like ***. Then I bought a Sound Blaster Live! Value and it sounded 300 times better. The mini-itx onboard sound is a nasty sounding nightmare. Dont use it
    BTW: msg hijinks (Jy) and ask him where the PCI extension cords webpage is... I forget but you need it.. Check out these pics..

    also, here is a shot of my mini-itx carputer b4 I mounted the sound card on top of it

    Just a quick update guys.

    Changed the mini-ITX standard sound card for a Sound Blaster Audigy 2 - completely transformed the sound - much more definition and clarity. Chuffed to bits!

    Of course, a week later, my amp's failed and I've lost my sub channels, but at least the sound stage is fixed
