What are the best tubes for a VTL TL 2.5 Preamp?


Will changing tubes really make a difference over the stock tubes? Which, by the way are made in China. My VTL uses 2 12AU7's and 2 12AX7"s. Will different tubes and brands make any difference in the sound? Thanks for any input.

before investing in expensive tubes, ask the manufacturer if the circuit is tube sensitive.

i have been told by at least 2 manufacturers that the brand of tube will have a very small impact upon the sound of a component.

i suggest that you consider ge 5814 black plate along with the other selections.
Mfb33,

"By the way, which has more impact on the sound the 12AU7"s or 12AT7"s?"

I'm not sure which has more impact since I swapped both at the same time. My guess is that they both do since the signals flow into both sets (1 set for input and 1 for output).
