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.
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!
