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

Well... I'm a bit surprised... I got the Hegel H590 to drive my 30.1's and 40.2's, because when I first tried them with the AR Ref 5SE and Ref 150SE tube amps, the Harbeths seemed to lack clarity and dynamics, and had somewhat boomy bass.  The H590 cleared all of that up, and really made the Harbeths sound like they do in the YouTube videos - which is exceptional!

However, I recently decided to try the AR amps again with both sets of Harbeths and was surprised that after some burn in, they began to excel with the AR amps - especially when using the 16 ohm speaker taps.  Amazing actually with a bit more air and bloom than with the H590 - much as you would expect from a Class A tube set up.  And the bass is well controlled, with texture.  Pretty amazing, actually!

I almost think I like their sound better with the AR tube amps, than with the H590.  Will have to switch back and forth a bit and see... but... right now... I'm truly amazed at the sound they're producing with the tube amps!  

Oh yes... the AR150SE produces 150 watts into 8 ohms.  Just assumed everyone knew that.  The Harbeths never require more than about 1/3rd of the potential - POT usually is not set above 35/100, which produces a volume level more than most can tolerate.   

I did not expect that the 150SE would drive the relatively inefficient Harbeths so well.  But... the AR does.

I'm using Manley Snappers (100w per side monoblocks) sounds amazing.

I am playing my Harbeth 30.2 XDs through an ARC 160S. No issues at all although the sound really opened up compared to the solid state LFD I was using previousl.
