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?

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.

Arcam may be ok for a receiver.It would be nice if they would give you the true power ratings at 20-20k all channels driven.A 80 watt amp is not going to drive a lot of speakers
that fall into the high end category.I don't believe it can give true class A at 30 wpc. Nobody listens to 1 khz only. A telephone does better than that.Arcam link.[http://www.arcam.co.uk/products,fmj,av-amplifiers,AVR600.htm#]Link to test specs.[http://www.hometheatermag.com/receivers/arcam_avr600_av_receiver/index3.html]
Correction for my last post.I should have said,true Class A at 20 watts per channel,all channels driven.Not some form of Class A whatever that is.

I believe a $500 a/v receiver will sound just as good as a $500 2 channel receiver or amp.
How may can you find that will drive 4 ohm speakers.A lot of mid-fi,and high end speakers are 4 ohms.
