5xG300 class-d amps (10 ch) sinewave

Never used 4 working sinewave modules, plus one module for parts G300 v.3 with all necessary wires (based on Tas5630)
These are high-end modules without caps in signal path (with dc servos)
$240 for all 5 (this is 1/3 of what was paid)

I switched on all 5 modules for the first time, one appeared DOA
Here are test results
THD+N and output power at 4 Ohm per channel (150W, 1%THD+N)
Frequency response at 1W at 4 ohm and 8 Ohm
Gain 31 dB
