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.

EH and Sovteks can be amazing sounding tubes so those are well chosen...Gold Lion 12AX7s (new ones) are great and not too pricey…NOS Mullard 6201s are also very nice, and yeah…you can tell the difference. I now use 6SN7GTBs in both my SE power amp and preamp (that has 4 of them) and have been having fun rolling around that tube…NOS USA Amperex, Sylvanias, blah blah…and they all make different tonal flavors.
I mentioned the 6SN7GTBs as between my preamp (Schiit Freya) and my amp (Dennis Had Firebottle HO) that's all there is for non power or rectifier tubes. My previous amp used 12AX7s and 12AT7s with my preference winding up as new Gold Lions for the 12AX7s and NOS Mullards for the 12AT7s.
