So quality valve sellers invest in good quality test and characterisation equipment so that matched balanced pre-amp valves can be identified. This means we have to individually test every pre-amp valve we have in our stock so that we can find the matched ones. This is a slow process as
I thought I would re-fresh this article because as you do listening tests you learn more and I thought you might like to here the updates .The updates are in bold . On one evening this week, I was at a friend’s house and we had some listening tests preamp valves in the V1 position in an amp. Here is a short summary of what we found.

We are expanding our range of valves and we are introducing four interesting JJ valves to our line up. The first three can help shape your amp sound in different ways.
