I just got a pair of m22 that I am running with a HTR-5960.
They sound really clean BUT seem to be muted or dry in the vocals. I listen to a wide verity of music. Some acoustic stuff sounds really good but other things like tool or red hot chili peppers have a muted or dull voclas, not alive and not right infront of you.

So my question is:

Will they sound different after some time? or do I need to look at a different speaker?

Thanks for you input.
