Hi, I'm not a Klipsch owner, but I have open baffle speakers which are 100db efficient. Also, I have a pair of high sensitivity Audio Note AN-E. I waited for over two years to get my Decware amp. I switched my order to the 300B amp about eight months ago from the SE84UFO25. End of January I finally received the amp and plugged it in. To my disappointment, I heard the hum too. It pressurizes my room at 120Hz with about 50db at my listening position. We are talking amp system specific hum, not ground hum or transformer hum. I listen to classical music often, and in quiet passages the hum is intolerable. I also exchanged mails with Steve Deckert, but he couldn't offer me a remedy. I was able to sell the 300B in no time. I told the new owner all about the hum issue and said he should check the development forum on the issue. The reviewers never mentioned hum. I think that is strange, they certainly should have heard it. One of my goals for my rig has always been to reduce the noise level and increase dynamic range. Unfortunately, the Decware just didn't fit into my system. Oh well, that, I suppose, is just part of the hobby.
