onkyo vs. Marantz A/V recievers which better?

I 2nd Ben's Yamaha recommendation. Go for the 2700 model and you'll be pleased.
Qualification: I have no business involvement, directly or indirectly with Yamaha in any way.
Good Listening!

I would NOT second the Yamaha recommendation, as I've NEVER been impressed with their ability to create a transparent view into music. All of their HT products as well as their Integrated receivers have a veiled sound to me, which creates a separation and involvement with what I'm trying to hear.

Of the two choices you're interested in feedback on, I'd select the Marantz over the Onkyo.

I am now looking also at a Denon 3806 and Harmon Kardon avr645. How do these rate compared to the Marantz and Onkyo. I would greatly appreciate if someone could provide a link to any customer driven reviews on any of these models.

I 2nd dawgbyte's response concerning Yamaha-thought I was
upgrading a few years back went from Harmon Kardon avr-85
to Yamaha-rxv3000-IMHO--there was no comparision in sound-
I sold the Yamaha--purchased a HK-avr7200-there is truth
to the high current sound that HK- promotes-highly recommended.Good luck.

I have the Denon AVR 3806 and I have no complaints. It produces solid two-channel sound and the video picture quality is very good. Rock solid performer.
