looks really interesting
I think I will give it a try
thanks

I'm not sure how much credence I'd give their marketing hype. They've got a 10WPC amp board too, that they claim is powered by the Pi. Let's see, a typical Raspbeery Pi power supply is 5V at either 2 or 2.5A. Lets give them the benefit of the doubt, and assume a 2.5A PS. So, we've got a power supply that can only supply 12.5W powering a 20W amp AND the Pi. That's not likely to work very well.....

It's also no the only Pi hat based on the PCM5242....

I agree
but I do not care about the amp just the DAC and low level outs.

the DOC's say 3 watt amp on board

There a a LOT of DAC boards for the Pi... There's doesn't seem like anything special compared to the rest of the marketplace.

From my post:

I was referring to another product of theirs. If they're going to give you a line of BS on one, they're probably going to do it for the entire line...

Caveat Emptor re specs. I tested a Behringer iNUKE NU6000 stereo power amp that was rated at 3,100W/ch into 4 ohms and when it didn't meet specs I called them. They said that was "peak power" and the RMS output was 2,000W/ch. It clipped at 1,200W/ch and the only way to get 2,000 was to drive it so far into clipping it was essentially a square wave generator. However, at 1,200W/ch it behaved quite well and at a price of $350 it is a steal for a high powered amp. The only downside is that like most pro equipment it has fans.

Maybe we should make it our mission in life to educate them. We could be heroes to generations of men to come
