Just curious, I guess I've been bitten by the SQ bug, would this be a worthwhile upgrade? Further, would there be a "bottleneck" caused by compression of any kind (128-320bit mp3 or 192-220bit ogg) or by my soundcard (audigy 2 ZS - yes I know it's not exactly an audiophile card, I bought it because I primarily game)? ie. Would it be worth it only if I had more CD/flac/miscellaneous lossless music and/or a more musical card like the M-Audio or TBSC?
