What power amp or integrated amp are you using with your Harbeth speakers

The problem with HUG is that AS clamps down on anyone giving a subjective report on the sound of a amp+speaker combination.  AS uses Hegel because they fulfil all his requirements/criteria for good electrical engineering, not because he favors their sound signature.

The point is that there are a number of pre-existing threads here and elsewhere that report good results with a strikingly wide range of amps, both tube and SS, and both modestly and high powered.

The Harbeth importer in the US has shown them paired with Luxman and Vinnie Rossi, among others.  Two major Harbeth dealers demo them with LFD and with high-powered tube Conrad-Johnson.

Bottom line: there is no unanimity.

agree w you completely

there is no unanimity - harbeths as high end speakers go, are pretty easy to drive, reasonably efficient -- and thus many many many amps work just fine, just depends on the priorities of the owner... better amps sound better for sure, the speakers, while warm and full in tone (p3’s less so than the bigger brothers/sisters), are sufficiently transparent to be true to the quality of source and the amplification

i personally feel the compact 7 and up like very high quality ss amplification more than tubes -- brings a bit more snap to the speakers and make the full bass more tuneful and tighter at the margin

yes alan shaw plays this game about being totally amp-agnostic - smart business decision, is all i can say... momma didn't raise no foo...

@jjss49 I agree with you - except had I not brought in my large Earthquake 300 w/channel, 1.6V line in, 120 lbs tank of an amp into my office to do a A/B I would have been content with the Croft. Used my second Metrum Jade DAC as pre.  

It definitely brought the Harbeth to life - adding more dynamics to the music with a punch. All the Croft details were there but with more authority. Vocals were a lot more clear and pronounced. After comparing I thought the Croft vocals were a little recessed. Earthquake made the Harbeth sing without fatigue and sharpness.

Call it a curse - but the reason why my interest in the Aria. Now could be that it's not a big difference between the Aria and Croft - from what you wrote - but that's why I have experts like you who have the experience across different amps and speakers help. 

I'm driving my 40.2's and 30.1's with a combination of the Audio Research Ref 5se tube preamp and the Hegel H590 using the Schitt Yggdrasil R2R ladder DAC as the source.  The sound is sublime in all respects.  As it is when just using the dac, preamp and amp of the H590 integrated.  

But... this morning I was surprised to find that driving the Harbeths with the ARC 5se and my Class D Audio SDS 470C is nearly as good.  It provides 300 watts @ 8ohms and 600 watts @ 4 ohms - plenty of power to control the Harbeths...

A local friend has a Coda Class-A amp driving his Harbeth SHL5s and I was smitten every time I heard them. Enough so that I went a similar route: Harbeth C7ES-3 (better fit for my smaller room) powered with a Pass Labs XA30.5 Class-A amplifier. Sonic and musical bliss.
