Constellation Audio Inspiration Mono 1.0

Award winning Constellation Audio Inspiration  mono amps.  Original owner, rated 8 only because age-3 years old- I see no scratches and certainly none on the face.  Amps were not hooked up from September 1 2018 -December 22 2019.  Hooked up and have played 20 hours to make sure working fine.  I have listened to them for approx 500 hours, (about 5 hours a week since I bought them other than Sep 2018-Dec 2019). I will continue to listen to them for 4-5 hours per week until sold. I maintain an active outdoors lifestyle and thought I'd listen to these more than I have. Amps sound unbelievable when driven balanced.  I would not recommend using them single ended, ie RCA plugs, as they don't sound that good driven single ended with RCA plugs. Owner's manual online, as with all Constellation Audio Inspiration products. I will require buyer get insurance for shipping.  Thanks for looking.
