Audio Research REF 75 vs VAC Phi 200


Anyone compared these two highly rated power amps? Both companies are well regarded in the audio community. These amps sell at approximately the same price point. The VAC may have a little more power.

Oregonpapa, I have read elsewhere that KT150's in the Ref 75 do NOT require the top to be left off. Can you clarify your comment? Are you saying the top won't go on due to tube height, or that you are not comfortable with proximity to the cover? On another forum, a member took temperatures on a Ref 75 cover with KT 120's and 150's and found them to be the same.
A lot of people who might try this tube may be disinclined due to a requirement to leave the top off, so please clarify. Thanks.
