Rogers High Fidelity EHF 200 MK2

I've owned one for about 8 months & love it! I bought it directly from Roger Gibboni who is the real deal - very smart & experienced guy.  Rock solid construction, sounds excellent & quite powerful. It does run hot & needs room to breathe. I generally prefer the ultra linear mode of operation but that's probably very room & speaker dependent. Best of luck - I'm confident you'll enjoy it.

I use the amp with the clear Lexan  cover as I have two very curious cats. Roger claims the amp dissipates better with it but I don’t know about that. Seems like most of the heat is of course on top but also substantial heat going forward from the front as that’s where the tubes are. 

i don’t have my sub connected directly to it as I use the Rogers w/ the theater by pass input ( # 3) for movie watching. I connect my main speakers  only to it for movie watching when I want a truly big theater sound. My sub is connected directly to my Anthem receiver. For music listening I connect turntable / phono amp & DAC ( for streamer & transport) directly to the other inputs on the Rogers & no sub required. Best of both worlds & don’t use up the tube life more quickly than necessary. 

I'm sure Roger can help you out. I don't use a sub when listening to music, my speakers w/ the amp don't need it. Its so great to be able to talk directly w/ the designer & builder of a quality American made product!!  It was one of the major contributing factors why I bought one.
