Electronics for Harbeth, Especially Monitor 40 series

I don't have the big Harbeths but for my office system P3ESRs I am using a Rega Brio-R, Apollo-R, and a DAC-R.  Works well together.

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.   

they work very well with hegel amps 

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.
