Thank you Bennett - Gian - what have you been up to with those bad boys? I am sure it has been more than just to power a rig and run Christmas carols through it for the office party and/or power the tree lights. I would love to hear some perils of wisdom.

Hi Sara,
Well, you're close. I actually bridged the amp, fed a 50Hz sinewave into it, and set it to 240V out. This allowed me to power my Euro import Christmas paraphernalia. Makes the TSO show look like a joke! Even Clark W. Griswold would be jealous.
Now onto its intended use (as claimed by the mfr.). I was hoping to get some more gigs on it and give a full report, but here are some highlights.
Definitely a capable sub amp. There is enough voltage swing to take peak clip-limiting out of the equation. Sound is "tighter", which I think is characteristic of CLASS D amps compared to linear amps (my theory).
A quick bench test verifies that output power is limited by the power supply. The max input current setting is 32A (via set-up panel) and this is where the amp stops delivering output power (~1800W at 4ohms with 1KHz rms input). With the line voltage at 120V, it's around 94% efficient.
