PENG, Thank you. The room dimensions I gave you are for my current listening space, but I am in transition, so I do not know what the future holds right now. Regarding your suggestion of a 2 or 3 channel amplifier, would this be a better option than a 5-channel amp? I presume that the rear speakers would be powered by the AVR and the sub, being self powered, would not require amplification. What is the advantage of getting a 2 or 3 channel amp for the front speakers over a 5 channel - cost? Thanks... Also, I posted a speaker system question in the Loudspeaker forum - do you think I should have posted my question in the Beginners and Audiophites forum or does it matter?
