just wondering what the loss in sound quality is if i am converting an mp3 to ATRAC3Plus format ( my MZ NHF-800 dosn't play Mp3 ), is a 1:1 conversion like 256kbps Mp3 to 256kbps ATRAC3Plus? should i convert to Atrac3Plus and a higher rate KBPS than the Mp3? just wondering i do not genrally have Mp3' below 192 kbps
