If it were my money, I'd buy a processor and three Temple Audio Gold amps or similar Class D amps. They are small enough to tuck away, much cheaper to buy and run, and will sound better than any but possibly the most expensive receivers IMHO.
“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”
