I owned one of those beasts about 5 years ago before I woke up and Moved to class D for surround ht system and never looked back.
I remember I bought it fairly local , about 120 miles so collected it and paid $750.
I do have the say the SQ was far and away the best I ever had from a surround sound all in one.
However it was huge, heavy and hot.
Sold it few months later for $800 so no complaints.
The point is that it was good, indeed very good in its day but I think you can do much better today for less cash.
I moved to all Nuforce for 7.1 pre processor and 8 channel class D power amp. Sure a few more interconnect but it was a massive step up in flexibility and SQ and runs stone cold and never touched it bar dusting it in the 5 years of ownership.
Just one example, plenty of options to explore today.
