You're the electronics expert, so feel free to shoot down these comments...
1. Aren't some DAC chips intrinsically balanced (eg. the one used in the Transporter)? 2. If you've already chosen your preferred DAC chip and it isn't balanced, how well would a pair of them be matched? Would a dedicated balanced line driver (eg. AD SSM2142, TI DRV134, THAT 1646) be more likely to deliver an accurate signal? 3. One possible advantage of using a pair of DAC chips is that in single-ended use you could sum their outputs to achieve a reduction in noise. (This technique has been used by Accuphase, and no doubt by other manufacturers too). ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
