Speaking of Quicksilver, specifically the V4s. Has anyone tried swapping out the supplies KT-88s with Golden Lion KT-77s? Buying 8 is not super expensive but I’d like to hear from others that might have tried this. I’ve been told the KT-77s are a little down on power but make up with it with a much more musical presentation, midrange to die for one dealer told me. Anyone have any experience they want to share. I’ve gone the KT-150s but still prefer the KT-88s to those for a more balanced presentation. Cheers
