I have Rogers High Fidelity 65V-1 integrated amp that I am super thrilled with to drive my Klispch Cornwalls. It is SET, pure Class A and is also a headphone amp BUT, it does not have BALANCED inputs. Most importantly, it is self biasing and can take EL34 and KT88 out of the box and can run either Ultralinear or Triode mode. It uses an iPAD app to control (input select, volume, Triode vs Ultralinear etc) as there is physical remote available. Not ideal but good enough for me. Also, you must have a load on the speaker terminals at all time when running the amp (including using it as a headphone amp)
Roger Gibboni's products are built like a tank, in the US of A (either Massachusetts or NY) . He doesn't do much advertising / promotions and is always under the radar but his prices are "reasonable" by high end audio standards.. I believe he is, for all practical purposes, a one man show.
GOOD LUCK !
