What solid state power amp are you using with your Harbeth Super HL5+ speakers?

Harbeth Super HL5+ speaker owners: Are you driving the Harbeths with a solid state amp? If so, what amp and how much power? Your impressions. I’ve been using a Conrad Johnson CA-150 (SS) integrated with my Harbeth SL5+ and the sound is nice but is underpowered at 135W@8ohms. Also, I would like a little more refinement with the amp. Bryston 4B3 perhaps? Thanks!

I'm using a 60W Hegel H90 with my HL5+. The pairing produces holographic imaging, a deep black background, detailed midrange and well controlled bass that is deep and powerful when it needs to be. It sounds clean.

While it can facilitate some magical moments (the singer and band is in the room, etc), I find that it rolls off a bit of the high treble, hence the black background. This is apparent once I switch to another amp that is slightly  more organic but a bit more vague in soundstage (an Audio-gd Precision 1 amp).

Despite that, ambience and reverb are still very much present and immersive with the kinds of tracks that emphasize them.

They are also in a small room, 10' x 12'.

I have the Harbeth Super HL 5+ 40th Anniversary speakers and I'm running them through a Pass Labs int 250. Absolutely love the combination. Sounds superb.

Using a Parasound a21+ driven by a Rogue Audio tube preamp.
Sound is as good as I could ask for.  Super smooth and refined.

Using the SST Son of Ampzilla II with mine - 220W. LTA Microzotl MZ2 tube preamp. Tried the Benchmark ABH2 as well, didn't think it was underpowered at all at 100W (and I have a big room), but didn't like the sound as much.
