I have been gradually improving this system to provide wonderful relaxed sound in a medium sized basement room. This is it for me. Ever improving has reached the end of the line. Time to relax and enjoy the music.
"I imagine your system is 98% of what is possible in audio."
Yes, it always makes tons of sense to attempt quantifying issues of quality. Reminds me of when I was a kid and somebody asked me if I thought "wrestling is real." He went on to explain that he thought it was 60% real.
So you can "imagine" all you like but what it has to do with reality is, well, nothing.
