Specifically referring to TPA3255-based amps with the typical 32 or 36V/5A brick supply. I see a lot of data in the various review threads -- are the power quotes peak (and I'd multiply by .707 for RMS)?
Looking at the Fosi V3 here:
Converting db to % it seems we're crossing the 1% threshold at 50W (with 32v supply). So perhaps an FTC statement for this amp would be something like: Minimum 35 watts per channel RMS at 8 ohms from 20-20,000Hz, both channels driven, with no more than 1% THD. Far cry from the "300w" number or whatever on the box. What do you guys think?
PS. My fingers are crossed for a 1974-style government smackdown. Get out your poly leisure suit and your flare-bottom corduroys; we're making honest watts great again!
