I have been watching the 990 thread and now that the most vexing problems appear to be solved by the new firmware I am ready to order a 990. I'm undecided re 7500 vs 7125. I currently have a 1050 with which I very happy. But, I'm seduced by "big iron." I have room on my shelf for a 7500, but I'm concerned by its 81 lbs. I will ask the cabinet maker about the weight problem.
I have a 6.1 setup using Mirage speakers (mains are OM-9) all around. If I buy a 7500, I will lose the rear channel. If I buy a 7125, I'm not sure what to do with the rear channel. I built the room around 6.1 and all the wires are behind dry wall. I don't want to open the celing to add a new rear speaker. Any suggestions about amp choice and what to do about the rear channel?
I have a Hsu TN1220 sub which is currently driven by a Hsu 250W amp. I have a hum (60 cycle) problem and will replace the Hsu amp with a 2200 monobloc, if it will drive the Hsu.
Thanks in advance for the advice.
