Audio Research REF 75SE and REF 80S

update to ref75se

autobias incorporated and a fan (one of the best things about ref75 was NO FAN!!!)

se designation was given to earlier reference amps to designate their ability to run newest most powerful kt150 tubes... now it is the standard tube, so no more ’se’ needed

seems like an update, not so much an upgrade, certainly not a new model/breakthrough... but who knows if and by how much the sound may have improved... my guess is not by much

Another marketing ploy to extract more money from the insecure and gullible.

It says can be played in triode mode as well as pentode mode. I wonder how triode mode sounds.

Its a "baby" REF160S.  New circuit board, etc.

The REF80S is to the REF75SE as the REF160S is to the REF150SE.

I look forward to hearing opinions as I enjoyed the ref 75....
