It would be a great service to me if I would have two systems. Onr for building stuff and experimentation, and the other a 'regular' but decent system not to mess with, but to enjoy music.
Most of my system I have built, and there are times that it sounds beyond what I thought it could. Then a demon enters, or I build yet another amp or speakers, etc. and the start of trouble begins. So, my merry go round is about me liking to build (most of the time) and ending up with anything fantastic to it's got a problem.
The disease for me is relentlessly building what I may not even need. Perhaps the cure is to go back to building furniture.
Being dissatisfied is not a good place to end up more than once.
