Have you considered a tube preamp driving active speakers?
I am not sure if the high input impedance of active speakers will prevent your tube amp from being stressed enough to make its lovely tube-like sound.
Matching with actives might give you both the nice tube sound and the deep accurate base/SPL levels. Something that you fear to miss with high efficiency passive speakers coupled with a tube.
If this worked out then, it seems to me, you would have your cake and eat it too!
ATC or Dynaudio make active speakers in a variety of sizes to suit your room/bandwith/SPL requirements.
Disclaimer: I have not tried this - so I don't know for sure if you still get the tube sound you are obviously looking for whilst driving such a high impedance load. I expect others may have tried this....
