That sort of makes sense to me . When listening to ripped CD's I seem to hear more detail in the instruments, and subtle details, yet the Streamed music sounds brighter. Its a bit confusing to say the least, but in a way makes a lot of sense.
I've actually found on a lot of pop and rock recordings I can tell little difference between an MP3 and a FLAC recording. Theres a little difference, but not a lot.
I can'r wait to listen to some Jazz or a few classical pieces, there should be a lot more difference there. Its either that or I'm just getting too old to tell the difference !
