Anybody own Audio Experience Symphonies?

I have been using the Symphonies (not the Plus) for about 3 years with a Canary CA-301 MkII. Wonderful bliss.

I replaced it (put in closet as backup) as I wanted a remote and phono section. I bought a Jolida Music Envoy. I rolled a LOT OF TUBES, got the Envoy to sound like I wanted. Then the Envoy broke and went to the shop. Out came the Symphonies, rolled tubes, got to the Mullard 10M's (lot of $$ for tubes for a Symphonies), but it beat the Envoy by a lot, and now the Symphonies is back as my main preamp.

The Mullard 10M's are wonderful in this preamp and beat everything else I tried. Here are the best combinations that I found:
1. 12AX7 10M Mullard (w/ 7025 GE in center)
(detailed, warm)
2. ECC83 Telefunken (w/ 7025 RCA in center)
(less detailed, more warm)
3. 7025A RCA (w/ EH-Gold in center)
4. EI-Gold (w/ EH-Gold in center)
EH-Gold (w/ EI-Gold in center)
EI-Silver (w/ EH)

Interesting note, the Mullard 10M's did not sound the best in the Jolida... I guess there is a synergy with other parts.

Update: I had Underwood mod the Envoy (spent $1600 on upgrade of preamp and phone sections), and it came back sounding much better than the Symphonies... so the Symphonies is going in the closet as backup.

I'm wondering what others are using for tubes. I have the symphonies v2. I am using 3 Mullard reissue 12ax7 tubes. They are nice, sweet and warm, with really nice highs but lack dynamics and drive and are a bit thin in the midrange. I also have Chinese 12ax7b which have a lot of drive and punch but are also dark sounding, lacking a bit in transparency, and have rolled off highs. I'm wondering what other options are available. I am thinking of the reissue tung sol 12ax7 or seeking out NOS tubes. I would love to try GT Mullard 10M or Chinese 12ax7C 9th gen, as I have heard these are really nice tubes, but no longer available.
