AV Receiver good enough for high end audio?


Have any of you found a modern AV receiver whose sound quality is so good that you are satisfied using it as your high end audio system? Did you toss aside your tube amp and just equip the front of your HT with a finer pair of speakers, a high end DAC, and done?

IIRC the reviewers at Stereophile Ultimate AV claimed the 5800 series Denons sounded as good as most good separates. Of course, the tube/vinyl guys will never agree, but I'm surprised they're not urging a return to a windup victrola with a cactus stylus just to be pure -- electricity gets between you and the waveform.

I have an older Elite 7.1 A/V receiver. I now only listen to 2 channel. I considered going with a $1,000 or so integrated amp and some new speakers ($1200 or so for a bookshelf sized pair. I would have to probably shell out closer to $2000 for an integrated to start to hear a major QUALITY difference to justify the purchase(I'm not talking bias characteristics like warm, tubey etc). I decided to place the money all in the speakers first and worry about the amp later.
as a non-techie, i've never fully understood why a well-engineered, no-compromise avr couldn't sound as good as comparably priced separates. now, i know in the real world manufacturers do make compromises, esp. in the amp sections, and that single-box components present challenges with power supplies and internal signal interference. however, i've owned or heard some avrs--most recently arcam avr 600 which sounded awfully good for 2ch music.
I believe a $500 a/v receiver will sound just as good as a $500 2 channel receiver or amp.
The Arcam AVR600 is certainly the best sounding receiver I ever heard and is also better than many separates I have heard too. The audio section is simply unbelievably good. It is probably the only receiver that operates in Class A up to 20 watts, which is where most music is listened to. This piece of kit is an astounding example of great engineering and Arcam is to be applauded in making a receiver the equal of many of the best separates and superior to all other receivers.
