I was retuning with Avia today and the right front timbre is totally different than the rest of the system (which matches very well). I don't remember noticing this before - had anyone ever had this happen? The front right sounds like its in a hall or something, but I've checked the connections, and it also sounds in phase with the left front (just way out of timbre).

I guess I should try switching left and rights and see if the mismatch persists, to narrow down the problem to either the speaker or amp.

Using a Rotel 1055 receiver and PSB Image Series speakers, with Tara Labs cabling (biwired fronts).

What happened when you switched the speakers?
