Nominally competent is easy. +/- 0.1 dB 100 to 10,000 Hz with less
than 1% clipping and no measurable odd stuff like a shut-down with
protection into the speaker in question. That's never been a secret.

Is it really that easy? It's hard to believe that if I find a $149 Kenwood
receiver that meets those criteria, use a high level input so it functions
as a power amplifier, it should sound the same as a power amplifier from an
established and respected maker, like Parasound or B&K.

You might also have to look at HF IMD or switching distortion, but
otherwise, yes. One of the best amps I ever came across was the Yamaha
AX-570, which cost around $400 in the mid-90s. For lower levels or
easier speaker loads, your $149 Kenwood might well be just fine.

And if it doesn't the same?

Then there will be an easily measurable problem.
