Report Hi-md deck at 352 kbps or Sony ES-serie at 292 kpbs? in Minidisc Posted August 26, 2009 It's actually a very difficult question you are asking. There are different uses for both bit rates. You therefore have to make a decision on what you want to use minidiscs for. From just a sound quality perspective I think 352kps may be marginally better, but SP has full stereo so it may depend in the end on the tracks themselves. I think, however, that the key to solving this is your *other* deck. Is it also a Sony SP deck? In that case having a number of decks in the same format would make more sense than getting an Onkyo Hi-MD deck. But your setup may allow both formats to exist side by side, so I can't say for sure. Basically it's this: if you want to invest in decks I would go the SP route; if you want to invest in portables go Hi-MD. If you want the best sound quality possible without the advantages of the minidisc format go PCM (uncompressed WAV).
