Even if they try and build a better receiver using better parts you still wind up with crap. Because, a receiver must by definition have a tuner, pre-amp, and amp, minimum. This would be bad enough but A/V receivers must also have a surround processor and multiple channels. Each and every one of these requires its own power supply, one of the most crucial elements of every component. Power supply quality is so important merely changing the diodes has a huge and easily audible impact on sound quality.
Now how many manufacturers do you think are going to put ten or more high quality power supplies in their receiver? None. Because before doing this they would ask, How many people are going to buy this two foot square 100 lb monstrosity? Answer comes back: zero. Which is why there are none.
But lets say someone is stubborn or nutty enough to try. Then they run into the next problem, which is shielding all those circuits from each other. Especially the chip-based ones that generate a lot of really bad noise. Now the box is so big and massive, well maybe the Mark Levinson crowd is getting a little chub on but that's about it.
Because then the next thing that happens, the few people who might be in the market for the world's biggest heaviest most expensive receiver are gonna look at it and say, "But I want a sub out." Or pre-out. Or 150 wpc. Or 300 wpc. Or.... anything but the exact combination of features the one you made has.
No. Sorry. Receivers are the Swiss Army Knife of audio. Crappy little piece of plastic that cuts nowhere as good as a real knife, clips nowhere near as good as real clippers, basically just gives you the false sense of having something useful when in reality its a red key fob with a white cross on it. Which I guess come to think of it makes it actually better than a receiver.
