After a lot of tube rolling (and I mean a lot), I decided to put back in the factory tubes from Decware (Tung Sol 6V6 GT, NOS RCA 12au7, EZ81,etc).

I just decided to listen and I loved the results (mellow, easy to listen to, etc.).

I know if I put back in my NOS Mazda 6V6 GT and the NOS Amperex 7316 (a 12au7 equivalent) along with a pair of NOS Amperex EZ80's, the sound will change (maybe towards a slightly more digital sound, but with better resolution?).

I just want to praise Steve Deckert on choosing some way excellent tubes to sell with the Mini Torii.

Any comments?

No Ruby Rectifiers (Chinese) in a Mini Torii, it uses the Vodka styled Russian OA3 and a Raytheon OC2 (American) along with a EZ81.

I also have some NOS RCA OA3 to try.

In my opinion, it depends on ancillary equipment and listening room characteristics. For example, in my conditions, the original tube setup was too dark and not too detail-oriented.

My current tube complement set is the best so far ... maybe still far from a possible optimal, but still a tangible improvement.

DAC changes are also significant in determining the end sound profile. I agree with Steve's proposed starting point of reference, but it is unlikely he could ever guess the inter-dependencies created by diverse conditions and tastes.

These days I enjoy more of my music and worry less on the ultimate tube setup ... Yet, tube-rolling with the Mini-Torii is still fun!
