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

Someone had large Spendor monitors with Prasound JC1s & JC 2 Pre, at the RMAF. I thought it was a very good room. It did have very high end analog source material though.
I understand fully why dealers pair them with British amps. That have sonic trademarks typical of British sound generally, speakers, amps. Harebeth being one of the biggest standouts. And they love amplification that share similar attributes, naturally. Something that shares and further brings out there strong points, as with anything else. LFD, Sugden, Exposure, Roksan. Someone coined PRaT and it stuck for good reasons, real reasons. Reasons I dont stray too far away from British sound, or away from at all.   
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.
