It's all about bit rate that your dac samples at. Traditional redbook cd's are 16 bit. Higher quality ones are 24 bit. Some Dacs are running at 32 bit these days.
If you desire high definition music much of it is either 24/192 or even 24/384. Essentially, the higher the rate, the faster your dac is sampling music for better accuracy and less noise or jitter.
Can I tell the difference between my 96 and 192 units? Only on specific higher bit rate recordings. My Chord runs at 384 and that is almost always discernable when compared to the 24/96.
