Ayre claims a 100 to 500 hour break-in, but doesn't specify whether that's total or for each input. Presumably those numbers come from Charles Hansen, the designer. I'm buying the KX-5 Twenty preamp to replace a K-5xeMP. The KX-5 Twenty is designed to match my KV-5 Twenty amp, and should pair well with my beloved C-5xeMP disc player.
" Ayre claims a 100 to 500 hour break-in, but doesn't specify whether that's total or for each input."
That's obviously what I should do if I need an answer. In retrospect, though, it is what it is. And when the KX-5 Twenty arrives I'll install it and begin to listen. I can turn the level way down, set the Sony HAP-Z1ES to repeat all tracks, and let it run while we sleep -- might even be able to set the KX-5 Twenty to standby. During the day, it can provide audio for TV, with only occasional bouts of music.
Sorry I wasted everyones' time with a poorly thought-out query.
Guess it depends on whether you listen to Coltrane or Desmond, Steely Dan or Queen, Haydn or Ligeti, Jay Z or Luther Vandross, Nancy Wilson or Aretha.
It doesn't matter which input you use. The main break in they are talking about is the signal caps/path and power supply parts. The input is simply a selector switch feeding the signal TOO those parts.
The only exception is phono input. All the others are electrically the same.
I am going to contradict myself and say this. I did find that teflon caps are an exception and do take a LONG time to break in. Mine took about a years in my CJ preamp and the sound did change a little.
