You will get better results, no matter which amp you choose, if you go with more efficient speakers. I believe that you really should have speakers that are over 90 db/w efficiency and preferably over 93 db/w. A tube amp will be more effective with efficient speakers.

Just for comparison, my vintage Lafayette 224A puts out 8 WPC and my speakers are 92db/w and it sounds pretty sweet. I am going to be building an amp shortly (TubeLab's Simple PP) that I hope to get 16WPC out of and will drive my speakers even better.

But there is no chance to drive my speakers with these amps? I'm listening to them with a nad 50 watt and, apart from a sound a bit cold, I seem to go well ... These canton karat m 40 dc.

Alternative is shengya a10 cs, ibrid amp whit 150 watt...

My setup used to be as follows:

1) PC or Arcam CD72 to Compass DAC (via SPDIF).
2) Compass DAC pre-amp out direct to power amp of NAD C370 (IMHO, compass pre-amp sound is better than C370 pre-amp, so I only used power-amp of C370).
3) C370 to Dynaudio Audience 52 (86db, 4ohm).

A week ago I replaced the C370 with Bewitch 6550 KT88 (now using the Compass as DAC only). Overall great improvement to SQ in all areas (low, mid, high, image,... cant think of a single area that didn't improve).

In terms of power, I'm just about ok with Bewitch in my small room (5x3.5m), but there is nothing to spare. For classical music with long sections below -10db, I need the volume at 2+ o'clock in triod mode. Compared to the C370 (with either DAC or C370 pre-amp), I never used to be beyond 11 o'clock.

Generally, I dont consider myself to play very loud, so if you like to blast or you have a big room, you will be borderline on power with the Bewitch.

Overall, I still consider the C370 to Bewitch upgrade as one of my best sound equipment investments as the SQ improvement greatly exceeded my expectations

I just hope the overal equipment quality will not let me down. I'm somewhat concerned as the transformers gets very hot after a few hours (especially the mains? in the center)
