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.

I recently upgrade my Cary 120 with new Gold Lion KT-88's and Psvane 6sn7.
Previously I had Gold Lions, but they had quite a few hours on them. I also had Tunsol 6sn7's
The Psvane Grey bottle are a matched Quad and the Gold Lions are a matched octet.
I'm constantly blown away by the increase in soundstage and detail, both high and low.
Psvane makes both a 12au7 and 12ax7.

I will be upgrading my Cary SL98P F1 from the Tunsol 6sn7 to a Psvane grey bottle matched quad.
I like the Psvance, that much.
