Interesting explanation. So, in the measuring environment you've described here, were you guys able to measure the differences in the soundstage that two audio systems project? Like, you could have 2 audio systems playing the same track at the exact same loudness, and one will portray a soundstage that looks completely different than the soundstage portrayed by the other audio system. Surely you've been in situations where you've experienced this? (some systems tend to be more 'forward' sounding whilst other systems may present musicians as if they're a few feet 'behind' the speakers) In which case, how do you measure that? What is your meter showing, what is your oscilloscope showing? -- magiccarpetride ------------------------------------------------------------------------ magiccarpetride's Profile: http://forums.slimdevices.com/member.php?userid=37863 View this thread: http://forums.slimdevices.com/showthread.php?t=85681 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
