Which high-end receiver?

Not aware of any buzzing issues. I can only share my own experience.

The demo model didn't buzz when I heard it - it had been playing music/movies all morning long in-store and then we played around with it for over two hours in the aftrnoon. I brought it home and didn't fire it up til the next day - played with it all week - no problems for me.

I'm not saying it never happens, but there was no buzzing on the store demo unit I had. I've had several Arcam pieces in the past and always found them to be reliable with good customer service. I don't like fussy components.

If you have a local dealer, I would try to get a home demo. It's an impressive piece.

BTW, I'm a realtor - congrtulations on the new digs.

Upgrade your wife.....HA HA HA JUST KIDDING

I think people should find out what's the real difference between good separates and receivers. If you take the Arcam, and put it up against some modest separates (budget even), you'll find dynamics is a huge factor, in favor of the separates!...my experiences mostly anway.
If you're willing to sacrifice dynamics, even at low volume levels, then I think you can find a lot of receivers that offer a good level of clarity, detail, and resolution, speaking stricktly of sonics.
I have yet to hear any receiver that can deal an acceptable level of dynamics for movies or music!
Given, when I go to a movie, the real passion, drama, and heart of a system is the dynamic level of realism it portrays. And I think most systems fail here. So, receivers are already dynamically short on "the goods". It's hard for me to give in this area personally.

I have an arcam avr300 and did have some problems with buzzing when it was plugged into my television inputs box (I have a lcd). I think you'll only experience that problem when something isn't grounded properly.

Rackon:
How does the AVR300 compare to your Cary/Herron 2ch system?? What topology does it use for the amplifiers??

Peter Moncrieff swears up & down that it kills a lot of high-end separates combos on 2ch music quality alone...
