I see used AV's receivers see from manufacturers who make really good high end 2 channel equipment and these receivers sell for less then say a 2 channel component from the same manufacturer
Yes and for a really good reason: AVRs are crap. Pure crap.
Its not that they set out to deliberately make crap. As you point out there's some decent names with decent 2ch rep making AVR crap. It is however always crap, no matter who makes it, and for good reasons.
One of the hardest things to do, and most important to get right in any component, is the power supply. A seemingly simple thing to do it is in practice quite hard to supply constant clean power. Hard to do with just one component. In an AVR one power supply is supposed to power a 5 channel preamp, 5 power amps, one multi-channel processor, one tuner, and God knows what else. Because AVR buyers all think the more they get the better the deal. They are in other words ignorant and misinformed. Don't be like that. Especially not now. Having been informed you are mono longer ignorant and would then have to be deluded. Don't. Just don't.
Sure, these AV's receivers wont compare to components that are way up there in the thousands but if your budget is bit tight I think these components would be great to start with and I am not talking about your $400 dealer receiver from best buy, I mean AV's receivers that were top of the line in their day and now can be had for much cheaper.
Yeah, no. Not even. Quite the opposite. The less you have to spend the harder it is to get quality and so its even more important not to search out a high value integrated and not squander your scarce resources on a POC AVR.
But hey, don't take my word for it. Just go back and look at those prices. Listen to price. Hear the message those prices are sending: this is all its worth- because its crap.
