Why no “Break in” period?

Electronics do not have a break in period. You are only accommodating to the sound of your system. Your first impression is the right one.


As for Paul McGowen, he will tell you what ever it takes to sell his equipment. He is not Ralph Karsten, Nelson Pass or John Curl. You have to take whatever he says with a grain of salt.

Nelson Pass, John Curl, and Ralph Karsten all believe in equipment break-in, burn-in, or what ever you want to call it. The late Charles Hansen did as well.

After all this nobody has given us a proven reason why a purely electronic device needs to "break in" after the manufacturer’s burn in.

after the manufacturer’s burn in.

"after the manufacturer’s burn in." ????

For what purpose would a manufacture need to "burn in" a piece of electronic equipment, wasting his/her time and money for such a purpose?

Circuitry adjustments yes..... "Burn in", though?? Again for what purpose?

What is meant by "forming" of an electrolytic capacitor?

Measurements.......

John Curl Interview Page 15/18


Also, we couldn’t use mylar capacitors, which are fairly efficient coupling capacitors. While mylars are fairly efficient from a size and cost point of view, we realized they have problems with dielectric absorption. I didn’t believe it at first. I was working with Noel Lee and a company called Symmetry. We designed this crossover and I specified these one microfarad Mylar caps. Noel kept saying he could ’hear the caps’ and I thought he was crazy. Its performance was better than aluminum or tantalum electrolytics, and I couldn’t measure anything wrong with my Sound Technology distortion analyzer. So what was I to complain about? Finally I stopped measuring and started listening, and I realized that the capacitor did have a fundamental flaw. This is were the ear has it all over test equipment. The test equipment is almost always brought on line to actually measure problems the ear hears. So we’re always working in reverse. If we do hear something and we can’t measure it then we try to find ways to measure what we hear. In the end we invariably find a measurement that matches what the ear hears and it becomes very obvious to everybody.
