Hi,
I posted this in the DAC-19 thread but thought I would post here as it's probably more pertinent and wondering if anyone had any thoughts ...
"So I performed the side grade from DAC-19 to NOS-19 using the dyi TCXO clock + capacitors shipped from Audio-GD. Upgraded firmware from DSPv7 to NOSv2 successfully. I was somewhat surprised that the sound is a little etchy/rough out of the gate ... I hope this really is the TCXO clock burning in! (On another TCXO clock upgrade page on agd site - "If you take the clock for upgrade, before sound compare, please burn in it. The clock burn in not myth, it is real effect the performance of the clock.”)
Well, I have let it run for 100 hours now and still the same. I was previously using the DAC-19 in NOS mode (upsampling in software) so by all measures and what Kingwa has stated, this should have been an improvement ... if you like the DAC-19 in NOS mode, then the NOS-19 should sound even better. Maybe I botched the soldering, though I would assume that it would either work or it wouldn't work ...
I am also using an SU-1 via I2S to the DAC/NOS-19 and wondering if the asynchronous clock in the NOS model is simply a big downgrade from the clocked output from the SU-1, and the re-clocking is making things worse not better. I guess I can try and go back."
What do you think about this? Is it possible that a bad solder is making the sound worse? Or is it possible that SU-1 -> I2S -> DAC-19 in NOS mode is that much better than SU-1 -> 12S -> NOS-19 because of the femto clock in SU-1?
