Question for tube aficionados


I have a vintage Conrad-Johnson PV 11 preamp.
 I’ve always re-tubed it  with the cheapest tubes from Tube Depot (e.g. Electro-Harmonix 12AU7 and 12AX7, Sovtek 5751 and the like.). I’ve been very happy with the sound.
 My question is:
 Would it be worthwhile to spend more money on more exotic tubes?
  Would there be any appreciable difference in the sound?
 I’m powering the system with NuForce Reference 9 V3 monoblocks.

"The difference NOS tubes will make is like cables - not much."

Interesting analogy except with cables you can show them off, not so much with many tube designs, particularly preamps. Just like anything else in audio, the depth of one's pocket is the only limiting factor.
