Krell K-300i vs. other integrated amps under 10k

I am looking for an integrated amp to drive my home theater L and R channels (Focal in wall with beryllium tweeters) as well listening to HIfFi using aforementioned speakers and possibly other speakers that I own. (SF Elipsa, Diapason, Focal utopia)

Options include MAC 7200 and Krell K300i and Hegel 360. I’m leaning to Krell.

I haven’t seen many reviews on the Krell, aside from Stereophile.

I’m unclear if Krell is a true Class A vs. class AB. There are reported overheating issues with this model, and it is reportedly voiced warmer than a classic Krell.

I won’t be able to audition either before buying.

I would appreciate any information on these amps especially pairing them to Focal beryllium tweeters.
