Hi John,I would consider replacing the DAC ceramic resonator with a proper crystal (1M res=2x caps) . That model is the poverty pack special bottom of the line plastic front panel unit- no headphone amp populated, no remote control receiver, no TOSLINK out and the crystal + caps are missing.
CDX-493 has the "upgrade":
View attachment 397707
Quick follow up on the above. Update performed, as you suggested, nothing else:
Here is a 1kHz before the Xtal update, this is 1khz with dither:
We get 1'001.99Hz instead of 1'000.00Hz...
After the Xtal update:
We get 999.93Hz, which is indeed much better but we're not quite here.
Worth another upgrade?
