Will Audyssey/Dirac compensate for different gain/sensitivity of amps?

[tifune]

I'm not sure how big of a problem it is, if at all, to use amps by different manufacturers with different input sensitivity and/or gain. Will Audyssey etc compensate for that? For example 2 channels of 230W @ 8 ohm, 1.1V sensitivity, 28dB gain and 2 channels of 350W @ 8 ohm, 1.6V sensitivity, 30.5dB gain.

2.5 dB is okay.

As long as the speakers are the same it should be okay.

Good point - they would be mostly pairs, of course. But it's for a surround setup and I'd rather just use random stuff I've acquired over the years, that wouldn't net much on a sale, instead of buy yet another box. Revel Be series - center and 226 L/R rated at 90dB, m126 heights at 86dB.

AVRs are usually well-equipped to SPL match everything without issues, this is necessary because most people don't have standard perfect setups where the distance between the listener and each speaker is exactly the same.

However, if you actually have sensitivity values, it might be a smarter idea to just match the low sensitivity speaker to the higher gain amplifier. But I don't think that's necessary either.

At least with Denon, as long as reference level doesn't require reducing or increasing the level of any speaker by more than 12db, then you should be fine in terms of level matching.

Other than amplifier gain, you also have to account for speaker sensitivity and distance. But again, in just about any case you should be fine.
