Just went through this, my old Marantz SR7010 has a short on the right channel terminal. It would shut off, and not turn on at random. Tried to pull it apart to fix the plug, but would have to disassemble the entire receiver to get at it. Decided to just get a new receiver (also could not find a local place to work on a HT receiver)
My setup is a 7.4.2, that limits what I can get to the higher end stuff. Finding anything in any local stores was difficult. Went to a couple local HT stores to play with what they had. After listening and playing with everything I kelp going back to Marantz. They have a good interface, good sound, and good price point. I did like a few others that were in the $8k range, but I wanted to keep it under $4k. No one had anything I wanted in stock. When searching the web, found a lot of good deals, but then they charged me both shipping and tax. Shipping was $150-250!
Then was on Amazon, they had a coupon for the Marantz Sr8015 this is the older model before the Cinema series. It's the top of the line, solid, heavy, and huge. Best of all, it was just over $2k delivered!
Been enjoying it for a little over 2 weeks now, it sounds better than my old one, works almost the same, feel like I got a deal for a top end product.
