I recently re-tubed my ARC monoblocks, the supplier had Svetlana "Winged C" 6550`s which were also "Cryo-ed" 100 hr treatment by Pearl. These tube`s made a great difference in resolution and detail.
Wondering if replacing the single 6550 in the Ref 3 with the "C" cryo-ed version would or would not be a good idea.
