Ted,
I hope that there is no such thing as "A perfect recording". If there is, then we are all put to shame.
Along that line, my wife, Georgiana, does beatiful Stained Glass work. Every so often she will say "It's a little crooked over here -- it shouldn't be that way".
I tell her, "Hey, it's a handmade work of Art, if somebody wants it perfect, they can go to the dimestore and get one stamped out of plastic!"
Most of us are our own worst critics. It can help us learn to be better, but taken to extreme, can stifle our creativity.
Just my thoughts - keep on keepin' on!
Walt
