If you're talking about this passage
Ultra amplifiers must be stable on all channels to 3.2 ohms and swing an 18A peak, while Select products must be stable into 4 ohms (front channel) and 8 ohms (surrounds), and swing peaks of 12.5A and 6.2A respectively.
then I think you should rewrite your first statement as follows:
The maximum current a Select 2 AVR must be able to provide to rear and surround speakers is roughly 1/3 less current than for the main and center speakers. For example, a THX select 2 avr must be able to deliver 12 amps to the main speakers but only 6 amps to the surrounds. Therefore, during dynamic passages in a movies the surrounds may not respond as well as the fronts.
Note that while your statement is true for Select 2, it does not hold true for ULTRA AVRs that must be able to provide 18 amps on all channels, so your first sentence is probably what got you those weird looks because of its implied overall generalization...
P.S.: And if you wrote your original statement for joebuzz's issue, then it does not apply since he has a SC LX86 which is Ultra 2, and therefore should have the same performance on all channels.Edited by info_dan - 9/26/12 at 3:38pm
