What 6922 tube will improve bass definition?
I have a Valve Audio Predator hybrid with stock Sovtek tubes. I want to improve the bass definition and grip. The Predator is driving Focus Audio FS8's. Both the Predator and FS8 are neutral but a touch dry, so a little midrange liquidity would be a nice added bonus. I don't want to spend $150+ per tube. Is there a modest priced tube under $100 that will meet these requirements? All suggestions are appreciated.
