Love looking at those studio pics. You gotta give it to those Vicoustic Wavewood panels. They really do help transform the room into an instrument.
Dan....When I look at MC2301s with grills on, I have to wonder whether I should go back to operating with grills on also. I like the look either way.
One could argue the possibility that the grills perform like a Faraday Cage and work like an EMI barrier. Then there's the matter about dust too... Although it is easier to get to the tubes and dust with the grills off, more dust does land on that beautiful chrome/polished stainless finish with the grills off.
The refresh hours are getting closer and I may have to get around to tube testing later this year. I am getting great life out of the Gold Lion KT88 reissues. How are you going with yours?
