I think any of those pre-amps are good choices.
ARC sp16 uses 6 12AX7 tubes, three in the line stage and 3 in the phono.
My TAD 125s and my ARC SP16 are in different systems. Would like to try them together someday with the Dynaudio monitors and OHM 100s in particular.
The ARC replaced a Carver C6 pre-amplifier and was a major step up in my main rig. The Carver is currently running the TADs and this combo is quite good in my second rig running Triangle monitors + M&K sub and Stax headphones.
