Old thread, but have to post that I built a pair of the Pass Amp Camp monoblocs - finished a week ago. Running with a 24v switching power supply rather than the 19v. I am quite surprised with how good they sound. They are powering SAM's. Makes me want to try a First Watt. J2 or SIT-2. Or a used Aleph if I could find one. A pair of linear 24v supplies with at least 2 amps each would be kind of pricey for the ACA's. That would bring them a step up, but would double their original kit cost.
.......PeterUsing a quiet, low speed fan since the 24v PS brings the heat up quite a bit.
