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.

So that's the problem with tube rolling, they sound different and depending on your tastes and your system they may or may not work for you. I found the Telefunkens to be pretty good, I liked them more than some Amprex tubes, including Bugle boys. As you wrote, they are great tubes, but just not in your setup. If you are already used to and like the sound of the EH, I think you might want something that hits with a little more punch than the tele or amprex tubes, I would try the new Golden Lions or the psvane, if you want to try NOS I would recommend you look at some RCA blackplates from the 50's or early 60's. I've tube rolled a lot of different tubes, and it's always a give and take with tubes. Amprex gets such a good rep because they are very balanced, but that might not be what you are looking for, and you don't really understand that until you try them out for yourself. Happy hunting
