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.

I replaced Sovteks in a Aesthetix Calypso with late 60s Blackburn factory Mullard ECC88 (6922). Got a much bigger improvement than anticipated. In particular bass weight and definition. Less than $100 for a matched pair, highly recommended. They've tempted me to order the premium 70s Mullard CV2492 version.

Thanx, for all the recommendations. I'll give the Genalex GL tubes a try. If these don't meet my requirements the Mullard ECC88 are next. Is there a specific(label-color)that is the premium version of this tube?

Just solve the problem once and for all with a Seimens or Valvo CCa. Telefunken CCa are great but not the last word in bass definition. The various NOS European/Brit e88cc, ecc88s are a good step back from the expense of the CCa.
