Yes, The wrightsound 3.5 2a3 mono blocks provide plenty of power through my Heresy III, and sound wonderful.

I don't think loudness is the only criterion though - power also helps for resolution of inner voices, but 3.5W into a Heresy is plenty for that, too.

I built my own version of George Wright mono blocs {I have his 2A3 circuit [xeroxed copy] hand drawn by George} and it IS an excellent circuit.

He had some novel grounding schemes and thought somewhat outside of the box in circuit improvement... DEAD quiet.

The chassis you see was leftover ones obtained after George had passed on.

The only changes made were to use 45 valves as well as 2a3 and as you can see, 45's being used. They drive Klipsch Forte II's plenty loud.

George was constantly changing and improving his design and I have not seen one set of amps that were exactly 'like' another {circuit wise}.

  Nice that you've got George's circuit diagram.
  
  I am noticing a bit of hum from my WrightSound 2A3s into the Heresy III - maybe the 99 dB HIIIs are showing an artifact I hadn't noticed in my previous 96dB speakers.
  
  But, it could also be the Wrightsound 20 pre-amp, which seems to have some idiosyncracies.
