Electronics for Harbeth, Especially Monitor 40 series


Hello,
Has anyone tried matching "fast" solid-state to the big Harbeths. Something like Goldmund, Soulution, Spectral, etc. The speakers have great tone but can be a little stodgy. I was wondering if this would open them up a bit. Also, has anyone tried using an LDR passive such as Tortuga or Lightspeed for the same reason

I spent quite a bit of time in the Harbeth room at the last Newport show. They were driving the 40.2's with Naim electronics. Very natural sound. Organic and emotionally involving, just as Harbeth always is. 
We have customers who really like their Harbeths- this particular model is quite tube-friendly.
They have been refined and defined, sold a ton, several tons since 77’ perhaps. It may be a safe assumption by now to say R&D has all but paid off on more than a couple of their more current designs. So when is cost going to come down on Harbeth speakers? :p
I never thought about at atma-sphere but it makes sense now that Ralph brings it up. They are fast and clean. If the speakers are impedance friendly and that's the sound you want, they are fine amplifiers in my experience.
