Who's using Harbeth with tubes, what speaker model and how many watts per channel?

I've heard my 40.1's and now 40.2A's with Primaluna and Cary tube amps and thought they made lovely music, but once I switched to solid state amps (LFD NCSE and now Hegel H590) I am much happier with the sound.  The 40 series speakers are hungry for power, and the two tube amps I mentioned did not provide this as well as the Hegel or the LFD.

thanks ralph your perspective is very helpful!

My favorite Harbeth/Amp combo was SHL5+ being driven by an Air Tight ATM-2 amp. 

The Air Tight makes approx. 80W, I used a Lampizator Big 7 as a preamp and DAC. 

The most enjoyable sound I've had in my home.

The ATM-2 is really an amazing amp. I regret selling and would love to find another.
