Thanks for sharing the results of your tests!
Did you get the AD797BR's already soldered onto those blue Teradak adapters from Audiojade on ebay?
I could easily suspect that they would be oscillating, but they sound so amazing and I don't get any audio artifacts....so you know
I agree that they're hot to the touch, but the top of the ONE was already hot w/ the stock opamps IME due to the voltage regulators and their big heatsinks. Anyway, most of the best opamps require custom designs to be stable, and they also cost too much for DAC manufacturers to use them. If the ONE came w/ 22 pieces of AD797BRZ, it would cost +$2K I guess, the only things we could possibly really care about are 1) audible artifacts 2) DC offset. I don't get any of these two
I believe there are tricks to make AD797 "unity gain stable", would need to check out their datasheet.
