Aiyima A8 maybe?

himmm interesting. I see in the TPA datasheets they use 51 or 53.5 v for the given spec. Didn't think class D's were that affected by supply voltage as they simply change the mark space ratio like an SMPS. learnt something here.

Heres an excerpt from the spec sheet of TPA3255.

Edit:
And here's that same info for TPA3251:

well not going with the 24v option now! Thanks for pointing this out.

Correct but the voltage of the pulses are higher and so the power supplied is higher with a higher voltage if all other things are equal.
