Since I am still very new to this, what is considered to ba a "top Of The Line" receiver? Also, what is considered to be the "low end". I am not looking to flame anyone, but just curious as to what is good and what is not. For reference, I have seen receivers on ebay, that must be low end - or fakes as they make them sound like the other companies names. I also see those systems sell for more than what Sadoun sells "namebrand" for. So, why not get a "namebrand"/better receiver?
