Thank you to everyone that has replied so far. I've been more than happy with my current Onkyo (HT-R540), but just recently got a decent deal on the pair of F2s, so I figure it's a good time to upgrade the receiver as well. I am impressed with the HT performance of the Onkyo, but when listening to music, it seems to lack the sound depth that it achieves in HT mode.... Is this something that the HDMI pass-through will help correct (99% of my music is played through my PS3 that is being fed music that resides on my PC through my network). Fairly new to this HT game, and any help is much appreciated...
