Matthew, just don't think too hard about it, I think that is key. You have a marvelous setup, and as it has been mentioned, would cost much more money to better it. Relax, enjoy it. You are at a point many others probably wish they were in, some state of contentment, which is so rare in this "hobby". Now more music, that is another story....
