My wife frequently asks the same question, but I'm sure the tone and intent is entirely different from that of your son's query. I'm down with your response - well stated. I have to say that as my system as evolved further, and as I get older (coming up on half a century in April) the tweaking aspect has been loosing its luster and I'm preferring just sitting back and enjoying what I've got more and more. At the stage my system is in now I'd have to throw copious amounts of cash to yield very small increments of improvement and I'm just not willing to do that. Life's too short and there's too much music that I haven't heard yet! Most efforts of late have just been in trying to find WAF-friendly ways to tame the room my system is in.
