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.

RV, I was really lost about the Belles ,my 150a Reference VII has no problem driving my 4ohm , 87db Totem Sig Ones which are hard  to drive .
Knew nothing about the DQ 20's . Worked internet , 4-5 reviews all noted how hard it is to drive, several said hardest speaker to drive they had ever encountered .
One said 250 watts a side was bare minimum , 400 would be better, guessed its to be a 82db load .

@schubert Very interesting, makes a lot of sense, and explains the situation.

@rvpiano Have you ever thought about stepping up to the Bel Canto Ref600M's?  From everything I've read, they could be your dream amps.

At the risk of being a homey .The BelCanto 600M's are only class D I would consider .
durk. Most Bugle Boys sold are fake .

It seems that the Telefunkens and Amperex are different enough so as to require an either/or choice. Some have said that the Telefunkens and Amperex are no better than new tubes like the psvanes... has anyone compared all three side by side?
