I have a new 7125 sitting in a box waiting for the elusive pre/pro with the right cost / benefit point for me. I am very interested in the AV7005 as it seems to be a good fit. I have a large room (18ft X 18ft) with very tall ceilings - 9 ft going up to 18ft. I plan on a 5.1 system. Can anyone tell me if it will be worth waiting for a Multeq XT32 component (possibly the 978) or will the Multeq XT be sufficient? What is Multeq32 going to buy me?
