Looking For A New Tube Integrated Amp With Very Specific Features

+1 for a Rogers High Fidelity Integrated amp. I have a bigger model in his line up ( EHF 200 Mark II) & really enjoy it. It’s built to a very high standard, sounds excellent & been trouble free for several years now. 

VAC Sigma 170i preowned would perhaps fall in your price range. Available with balanced inputs, remote, auto bias but alas, no headphone.

FWIW – not SE, but the Linear Tube Audio z40+ ticks all of the other boxes, and is the best amp I have employed over nearly 50 years in the game.
