Your best power & preamp tubes combination?

So far, best combo -- CJ MV60 amplifier, is Tung Sol throughout. My experiments:

Electro Harmonix 12AX7 w/ Tung Sol EL34B
Tung Sol 12AX7 w/ Winged C EL34

The EH 12AX7 with Tung Sol EL34B sounded good with a somewhat closed-in sound stage.

The Tung Sol 12AX7 with the Winged C EL34 sounded like an excellent solid state amp -- big soundstage, shimmery tone, voices a bit recessed.

Tung Sol 12AX7 with Tung Sol EL34B: big big sound, very live sounding with excellent reproduction of voices. Might be a bit much for tube newbies :-)

Primaluna Dialogue One with NOS Russian Reflector 6n3ce; NOS Amperex Bugle Boy 12au7; NOS Sylvania 5751 black plates.

EL34s, Psvane along with above mentioned driver and input tubes.
