A lot was already said about this fantastic day at Jon’s. The Starlight CD + Discrete DAC festival didn’t go as planned but we had a wonderful time. I had the chance to bring my own Starlight and sounded nice in Jon’s system despite the ground loop issue. Not clear what it was, despite it played well at low AVC levels but not when volume was increased. Perhaps was the load? Anyway, lots of tests from differential DACs to cathode follower outputs and Tom’s bipolar version.
I have to admit that the transformer coupled DAC sounded very transparent and detailed. The valve output gave a warmer tone and even harmonic contribution. The 6N1P implemented as cathode follower was very well received.
Tom’s bipolar DAC implementation is very promising. Clearly the tiny DC bias saturated the AVC and bass wasn’t good. Once we added the coupling PIO it came back to life with a subtle sound I enjoyed very much. Some challenges aside with the ESL resonances which I hope Jon can sort out soon.
Food and hospitality were superb in another unusual warm September day.
Most of all, a great day with fantastic company.
Thank you all
Ale
