Glad to see a Marantz thread started.
I am an owner of a SR 7400 and thought I would share my experience so far.
First the good.
I concur with most other people that the Marantz has a wonderful sound and if you listen closely, would concur that it has a warm sound but not night and day different than my previous receiver, the Yamaha 2095.
I purchased a refurbished unit from accessories4less and their service is excellent and when i had a probelm, they were very responsive. When I had to send my unit in for repairs, they advised me where to send and volunteered to provide me a copy of my purchase invoice if i needed it. In addition, the repair facilty was very fast in repairing the unit and were cooperative in responding in a professional way on my second unit problem by agreeing to pay shipping the second time.
Now the bad news. This is my first Marantz and in my many years of purchasing hi-fi equipment, the first reciver I have ever had a problem with and now I have had two in less than 6 months. The first problem was that i was not getting any sound. No matter what source I fed the receiver, it would show on the FL screen that it was analog then the speaker configuration screen would dissappear. When i got the unit back and set up, after some doing, I got the sound out of all speakers but no FL screen no matter what I did.
When I contacted the repair facility, they assured me it was working when it left them so it must have been done in shipping and informed me that i would have to pay shipping again. When i complained, they referred me to someone else who immediately made arragnements to have it picked up the next day at their expense. The turn around time was quick and I anticipate this repair to be fast. I will post my findings when it is returned again.
