Thanks - good to know similar issues have happened before. I was going crazy with this...

I have been using my KPA with great success for about 2 months (full disclosure - KPA was purchased used). Never had any problem from day 1. Since about 1 week, when the unit is turned on, it sounds fine for about 5 mins. After that, it sounds as if it is power starved: volume drop, no definition, no attack, and profiles sounds almost all the same. Not usable.

I am monitoring through headphones. Have tried: changing headphones, cables, guitars, and power outlets in the house. Same problem.

What is driving me nuts is the fact that it works totally fine for 5 mins, and then the sound quality drops so much.

I think the KPA is still under warranty, so I will get it fixed. But does anyone have an idea what can cause the sort of problem I am describing?

Thanks!
