Your system looks quite nice, but it's also really making me think about turning my already silent windows machine into something similar. I have a Sound Blaster Audigy with a SPIDF out that will upsample into 96k, I guess I'll just have to try it. Are you using iTunes to import your songs? I'm trying it out and also trying the variable bit rate WMA, any thoughts. You mentioned errror correction, do you mean just during the ripping process or is there any kind of postprocessing going on in your G5 before your digital output. Ever considered any kind of DSP between your G5 and your DAC, I have no experience with such things, just curious. Your system looks like a rotel advertisement, as they use B&W in them. That's a compliment. I'm also a college student and recently posted my system. In your search for a DAC I've heard the older Adcom (ugly) GDA-700 are great especially for the money, and there is always Theta Digital's used stuff. I'm currently looking at DACs as my CD player is not the greatest, I think I'll get the Adcom. Best of luck with your system, it looks quite enjoyable.
No sub?
