Krell and Audio Aero are at the two opposite ends of the audio spectrum. The Audio Aero is a hybrid tube amp, and the Krell is pure solid state. It really depends what you're looking for.
The Audio Aero's SN ratio isn't that high. But it doesn't bother me, not for a second. There are some, though, for whom it might be a deal breaker. It really just depends on your taste and your setup.
Personally, I don't like most of what Krell has to offer. It's too clinical for me. Some don't like what Audio Aero has to offer, because it's too euphonic, or too whatever. I've never heard Kora.
The Audio Aero is very, very musical, and at the price I think it's hard to beat. Also, it benefits from tube rolling greatly.
