For any PL, swapping the two 12AU7 in the middle with better tubes results in the most significant improvement, but there are audible benefits in upgrading them all. I myself have used matching aftermarket tubes for the two in the middle and upgraded the other four with a matching quad of another brand. I’ve also swapped all six out. I’ve never used three types of 12AU7 in a single unit. If anyone does, it should be done in mirrored fashion from the middle.

As you guys know, this integrated has 6 12au7 type tubes in front.
My question: Do you guys use identical brand tubes across the board or do you mix brands up in the same family and in a specific order to get better sound?

@thecarpathian I mean to ask as well, have you upgraded the power tubes? |
