I installed my Blues into my amps. Initially it was similar in effect of using the Blacks after they were broken in times 25%+. I liked the flow of the music better with the Blacks for the first 45 minutes. Then I listened for another 3 hours. The Blues became so much better than the Blacks. It wasn't just the increase in resolution, spaciousness, openness, it became like the Blacks, more intimate sounding. The tone of instruments are now fuller than the Blacks.
This change was similar to my change from my IC cables which were the same except for the reduction in capacitance by 50% by adding a teflon sleeve over the positive wiring. See http://www.groverhuffman.com/home for details (his cable already incorporates a tri-metal powder based shield with a copper mesh outer shield). It was a major improvement resulting in extended frequency definition, spaciousness and dynamics.
The result of using the Blues is so much more information and enjoyable listening. Not just for me but for my wife and visitors who can sit five feet from the sweet spot on either side and enjoy nearly the same sonic features as the sweet spot. (My wife had me get rid of my large electrostats 18 years ago after we married due to their limited dynamics, bass and listening space-center only).
I'm so glad that SR listened to my suggestion (if they did) that audiophiles would pay extra for broken-in fuses rather than burn up 72 hours of tubes to break them in. That the price is only $20 more than the Blacks is greatly appreciated.
