Question regarding the test tone -- is the 950 supposed to produce an *identical* test tone for all channels (or at least the front 3).

I'm running a 950 + 755 and three identical speakers for L-C-R (M&K SP-150's). I'm surprised that the center channel seems to sounds a bit higher in the test tone.

Does any one else that run identical amp+speaker for Left-Ctr-Right experience the same?
