There are several, actually many 50 watt or so amp boards that PE and other suppliers sell, but I see very few higher output boards available.

For instance, The Dayton

I like this amp board,

It does 50 watts stereo and is nice and small, but I'd love a bit more power, say 75-85 watts in a similar size would be great.

I think the higher output boards like the Dayton DTAPRO and the Lepai LP1601S use BTL to get to the 80-100 watt per channel mark, but is it that hard to do so in a compact form factor?

Just wondering if there is a reason why 50 watts seems to be the limit on the small boards; and does anyone know of an amp board similar in size to the TDA7492 that puts out a bit more watts, like 70-80 or so into 4 ohms? Even up to 20 or 22 volts would be okay.

Thanks for any thoughts,

For instance, The Dayton

DTAPRO

has around 100 watts for the LR speakers and there's a Lepai that does as well, the LP1601S, and these are finished amps in cases, but there's

not much in the small amp board category.I like this amp board,

The TDA7492, I

have used it a few times: https://www.parts-express.com/tda749...2x50w--320-606It does 50 watts stereo and is nice and small, but I'd love a bit more power, say 75-85 watts in a similar size would be great.
