In Reply to: The polarity of DACs posted by georgelouis on March 25, 2007 at 08:25:18:
Dear inmates and music loving audiophiles,I have a Sony CDP-990 CD player with two 18 bit 16 x over-sampling Analog Devices DACs per channel in a dual differential configuration and both its digital toslink (it only digital output) and analog outputs are inverting. Therefore, there’s a polarity inversion even before the DACs. My two drawer Tascam CD-RW402 professional CD duplicator inverts the polarity of copies made either directly from its playback drawer to its burning drawer or made directly to the digital input of its burning drawer from an external digital source. And in that case no DAC in the burner is involved so again there’s a polarity inversion independent of any DAC. It also seems to me that most standalone CD duplicators such as the RealityCheckCD Audiophile Grade Replicator, Cool Copy, and Alesis invert the polarity of copies relative to the source that’s being copied.
