PWM is Pulse Width Modulation. Basic concept of how switching power supplies work in computers. That's how they are so darn cheap and light. In my world of programmable controllers a power supply putting out 450 watts at 5 volts goes for over a grand. Its just a transformer, regulator, and filters. A computer power supply will put out the same using PWM for thirty bucks delivered to your door

Interesting topic. I mentioned that I did sound reinforcement. Did I also mention that I taught A to D and D to A thirty years ago? I still have a ton of boards. In those days they were thermometer and then microprocessor controlled oversampling. Very slow microprocessors. Z80's at 2.8 Mhz and we programed the code. I moved on to direct applications of pulse width modulation in the early '

Thank you both.. it's about as good as I can do with a cardboard box, haha..

Now as for a break in period - there's very strong opinions going both ways but logically I don't see how something like that would sound any different after breaking in. I sure hope it does since I don't hear any difference now. One thing I really do not see are examples of when people compare

Very clean work. Looks pretty.

Electronics don't have bearing surfaces so don't expect a break in period.

Good job! Very creative.
