PC Based Audio - How?


I am hearing a lot of good things about PC audio as a replacement for conventional CD players. My question is threefold; first, what are the basic components I need to run a Mac laptop based PC audio system? Secondly, is it possible to simply feed the digital output from a Mac laptop (or MS Windows laptop) into my Krell HTS 7.1 processor for D/A conversion? Finally, any advantage/disadvantage using a laptop over a desktop for CD storage/playback? Any comments on equipment choice (say for a $2k budget), software and file ripping/storage formats would also be appreciated.

Thanks in advance for your advise.

Regards,

All,

Many thanks for your good advise. I used to aspire to a dCS based CD player, not anymore though! You have convinced me computer base CD play back is the way to go. Can't wait to give it a try. Thanks.

Me too. I'm glad I did some experimentation first to change my mind....
Do some reading - find a DAC that is reknown for jitter rejection and that accepts all the standard digital inputs (AES/EBU, S/PDIF, TOSLINK and now USB) and off you go - start auditioning for the sound style you like (all D to A converters will have subtle differences).

Unlike what Eric says - as long as your DAC is robust at jitter rejection then you can even consider an Airport Express or just about anything else which has less than stellar jitter performance.

Think about it - your source may likely change over the years - so apart from finding a DAC that you like the sound of - your biggest consideration should be to find one with as many inputs as possible and reputable jitter immunity...then just plug and play.
I've been out of audio and A'goN for over two years, but am getting ready to jump back in this time with a Mac based front end.

Right now I'm looking for my best options using the USB output from a Mac into a DAC via I2s, bypassing S/PDIF altogether.
