I have a BIII 9038 coming in the mail tomorrow. Today, I tested my Placid HD 2.1 on the bench, and could not even get 500ma out of it with a load resistor. This DAC supposedly needs 750ma, and I had planned to power the Cronus off the same supply.
Brian at TPA said it should do the job. I had it connected to a 15 ohm load, and the supply dropped to around 2.5v. With a 25 ohm load, about 200ma output, it worked as it should. The voltage was right at 5.00v and the shunt current would adjust to about 50mv.
I do remember swapping a resistor, with a jumper wire, on my old placid. It did something similar when I added the Trident Regs to my Buffalo II...
Is anybody here running the BIII 9038 and Cronus with the Placid HD 2.1?
Thanks,
Mike

Solved, at least somewhat. I was able to adjust the shunt current (with many turns of the pot) to get 5v into an 8 ohm load, about 625mA. So, it may be close to set for the DAC now. Also have some bigger heatsinks if needed...
