I was told that the PSR-1000 has 8 mbs of sound, as does the PSR-550.. However the 550 has less sounds to the megs as the 1000 does.. Is it safe to assume the PSR-1000 would sound almost identical to the PSR-550 in terms of sound quality? Is the price difference based primarily on the new internal memory for recording, screen, new look, and a few other things?
