Hey people, Have been recently investigating signal to noise ratios of various portable audio units..especially with regards to mp3 players. A higher value signifies better quality and lesser noise. i found creative micro zen to have a 98db signal to noise ratio with less that 0.1% harmonisation distortion which is really good when StN ratios range between 88-96db on most other mp3 players anyway, i love good sound quality and consequently purchased an rh10 which is pretty decent sounding with my E2cs but hoping to upgrade to the E4cs soon.. to cut a long story short, does any1 know what sort of signal to noise ration we're looking at for the Rh10 cause sony dont seem to have this figure anywhere.. i'm hoping it exceeds the creative considering i bought the minidisc for its superior sound quality best regards nick
