And it is dependent upon the types of music and when they were recorded and most importantly for WHOM they were intended for.... a top system will sound FABULOUS with Claire Martin but will never make a Cinderella (80s rock band) or a Van Halen diver down (even the band admitted it was a terrible production) album sound worth a darn, the problem is , I enjoy BOTH... the more revealing a system gets, the more awesome Claire will sound and the more forward and nasty my beloved 80s rock will sound.... I think it is just finding a balance between your types of music and all their respective recording qualities, your gear and your ear.... I love resolution, but like everything else...there is a limit where you can reach the TIP of the mountain and things start to slide... so back up and stop there and just enjoy.... so far the best sound i have gotten with cds, is ripping them on my hard drive (amazing improvement in low level detail)... so i agree , the next jump in sound quality lies in a hard drive and yes a TOP dac.... this is just my experience though...
