Well, in principle many speakers are better. After all, you could put a mic on each instrument or sound source in the original recording, and then play the music back with a speaker physically positioned in the same way as the sound sources were during recording, and you'd have a perfect soundstage :-). I once read about such a set-up for piano music, with one speaker for each couple of piano strings. Of course, this obviously isn't practical for many reasons, one being you'd have to re-arrange your speakers every time you listened to someting different. Still, I wonder whether future technology might allow an amplifier to sense the position of each speaker (and perhaps of the listener as well), and then dynamically adjust the output from mulitiple speakers to best emulate the oiginal sound... -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=22717 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
