Deciding between Yamaha or Marantz

I use to have the AV7701, but whenever I had any type of component connected to it, there would be a hum/buzz coming from all 5 speakers. I tested the amp, Oppo, PS3, cable lines and TiVo. I've returned multiple AV7701s, I tried the Oppo as my pre, no noise, I tried a different pre and no noise. Just seems like the AV7701 isn't playing nice with my components.

If you're budget permits the new Marantz AV8801 around $2300 has a great review on home theater magazine, I've had Marantz AVR and like them very much I also had several Yamaha AVRs and prefer the Marantz.
I now use an Arcam AVR400 that I'm happy with.
Good luck!

Thanks for your suggestion, if I could find the AV8801 for $2300, I would get it.

I sold Marantz for a very long period. In the past I loved it a lot. But during time Marantz started to use less expensive parts in there sources and amps. This changed the sound i the lower price range Marantz works. They use quite small transformers in there amps. When you compare it to Onkyo they use more and better parts. So what is the difference between the Onkyo PR-SC5509 and the Marantz AV8801? The focus of instruments and voices is a lot sharper with the Onkyo. But the biggest difference is when you use a higher level of amps and speakers which also can give a wide and deep stage. The stage of the Onkyo PR-SC5509 is a lot wider and deeper when you compare it with the AV8801. Marantz is what we call a more 2-dimensional image. I am also a Audyssey installer. With Audyssey Pro and the Onkyo PR-SC5509 I beat many even stereo pre amps of 10.000 dollar. With the Marantz I cannot get the stunning 3 dimensioanl image of the Onkyo PR-SC5509. Yamaha is not of the same level of these both.
