I believe that the big changes in the sound were in the first 40 or 50 hours. Didn’t notice sound changes after that.
The problem was the noise, the sound was grainy and harsh, but now finally is OK. What remove the noise were the Herbie’s Audio ultrasonic tube dumpers. The noise was from the tubes and those tube dumpers made a great improvement.
