Amplifiers in use with big Harbeths (Mon 40 series) that work very well

I used an Aesthetix Calypso with NOS tubes.  

While the Plinius was the best solid state amp Ive owned, I haven't owned a lot of SS amps as I prefer tube amps.   If I had to use SS, the SA 102 is an amp I could live with.

Thanks for the response. The Audio Research LS16 Mk2 sounded best with the Plinius SA-100Mk3 on the Harbeth although the overall combined system wasn't cutting it. I suspect the SA-102 is a significantly better sounding amp than the SA-100 and the Aesthetix Calpyso is a good match to it.

appreciate the inputs and discussion so far

the mon 40’s represent an interesting challenge for amplification... highly resolving, not super hard to drive, but hard enough that really low power amps need not apply -- moderately efficient, so doesn’t need a ton of power, but really likes more power if it is uber pure

responds well to tube beauty but with the big woofers you will certainly give up something on the low end in the trade

like many great speakers, it may have some of its own personality but it let’s you hear pretty plainly what you are driving it with, good or bad

Curious if you’ve tried the Audions with them and how they fared.

Tried Luxman 590AXII, Hegel 390 and Line Magnetic 805ia with 30.1’s and HL5’s. Prefer the LM by a large margin. Holographic sound that the other SS amps do not offer. I’m a fan of high powered tubes!-Alex

For a non tube amp that works well with big Harbeths I would recommend Dartzeel integrated. End game amplification for end game speakers! 😃
