I have the HT-S7100 practically the same as HT-S6100 with the TR-606 receiver. Yep still going strong since i bought it as a "refurbed item" back in 2008!! I only added a fan on top of the unit to fix the overheating problem and is in an open home theater stand. I have not upgraded anything on it, still the same speakers that came with the HTIB . Still enjoying the awesome room filling sound in my home.
