Default Pass D124/96 with PCM1704K??

I came across an old post from 2003 at Audiogon ( http://forum.audiogon.com/cgi-bin/fr...gtl&1063887965 ) which said:

"I think it sounds so good because of the unique D/A stage designed by Wayne Colburn at Pass. Does yours have the 24/96 upgrade? If not, you may want to look into it. Wayne replaces the four Burr-Brown PCM64K Dacs with eight(!) Burr-Brown PCM 1704K Dacs as well as some other changes."

The conventional wisdom is that the D1 is a PCM63 based dac and the 24/96 was a reciever board only upgrade, so I'm curious if the 24/96 D1's left the factory with PCM1704K installed?

There was only a receiver board upgrade. I don't recall any change of DAC chips. Both chips are R2R types, but with different packages and pinouts.

The information on Audigon is actually correct. Wayne Colburn confirmed that for the standard 24/96 upgrade each PCM63P-K was replaced by a paralleled pair of PCM1704.
