I think I already conceded that measurements aren't everything. However, a lot of people seem to care about jitter and power supply noise, and these are measurable things where we can easily show that x is better than y, and by precisely how many db or whatever. And I never said Transporter sounds "2 times better" than anything, so please don't put words in my mouth. In fact, I wouldn't even claim it "sounds better" than a tube amp, although I can tell you precisely how much better the SNR is, for example. Can I hear stuff 120db down? Nope, I doubt it, but some other people here on the forum have proved that they CAN hear some pretty incredibly tiny sounds, such as the effects of different rounding and dithering algorithms applied to the LSB of a 16-bit signal. Also, have you considered that there could be things you can't consciously hear even at -60db (or even at full volume, eg phase linearity), but which might be absolutely critical to conveying realism? -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=29450 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
