Yes, when the system was working in my room after a lot of experimentation with set up and room acoustics, I achieved a sound with which I was very happy. It was all working. But I wanted to push it further, which lead to the Lamm electronics, not OTLs. The M1.1 hybrid amp was excellent in my old system, but I wanted to take it further, which led to the ML2 SET, and very efficient corner horns and then upgrades to my Lamm electronics to the Signature series.
Pushing it even further lead to more experimentation with set up of turntable, speaker positioning, and room acoustics and resulted in more improvements. There is a new found calmness and joy that comes when knowing one is achieving his goals.
