For me, Klaus was easy to reach (so much so that I was initially confused!) He was very patient with me and all of my questions. He asked a lot of questions about my system, what I listen to, my room, etc. He actually recommended I buy something less expensive from him than I was originally thinking about! When I called a third time to explain with embarrassment that due to things in my personal life I would not be purchasing a pwr. amp, after all the time he had spent with me Klaus remained polite and even gave me a few tips before the call ended.
None of us is perfect; Klaus is a mensch (that’s Yiddish, and a very high compliment).
