"When in doubt do nothing". Somebody important once said that but I don't remember who. Also Albert Einstein said " the definition of insanity is doing the same thing over and over and expecting a different result".
Now I don't know what either of these has to do with anything here but they sounded pretty impressive to me. I think that at some point you just have to be happy with what you've got. If I won a lotto I'd keep my current stereo system and start shopping for a new BMW M3. With cars there's a significant demonstrable difference between a new civic(which I own) and the aforementioned Bimmer. With stereo amplifiers, not so much.
