Charlie the Axiom mains (M22ti's) have two sensitivity ratings. One is rated as "SPL in room 1w/1m" and that's 93db. The other is Anechoic SPL 1w/1m" and that's 89db. My feeling is the 89 is probably more accurate.

If in fact the speaker/receiver combo is underpowered, then I'm in a quandry as to whether it would be better to get bigger speakers from Axiom (M80 w/ respective 95db and 91db sensitivity rating) or a bigger amp from outlaw (the 755 using the 1050 as pre-amp).

I just want to be sure that the crackling highs I'm experiencing would be a symptom of having the outlaw volume up too high. Do you think 65/80 on volume would be considered "too high", or enough so as to crackle the voices unbearably?

Thx for your response.
