What's next after Luxman 550 AX/II with Harbeth C7

I recently bought and sold the Luxman (class A) 550 for my C7's. I won't waste all of your time with reasons, but let me sum it up with saying the pairing was good, but nothing special. I would go as far to say the Croft phono integrated I had prior engaged me a bit more. I'm now considering the Unison Unico integrated. I know this will sound odd, but the other integrated I'm considering is the Lab twelve integre. The latter cost $5K US, while the Unison is less than half the price of the all tube Lab twelve. No offense to anyone , but I'm not considering any all solid state units. The Unico is a hybrid, so I thought for the money, it would be worth trying. Just to avoid confusion, the Lab twelve actually used the numeral twelve, but it seems that audiogon flags my posts whenever I put in a number. So I spelled it out to avoid the aggravation. Life is hard enough (-: Hope everyone is staying safe and healthy. Cheers -Don

I just looked at the measurements from What HiFi.

Those speakers need close rear wall support to have decent bass, and an overly lively room will accentuate the treble in comparison.

I suggest, if you haven’t, get them closer to the wall or use the absolutely fabulous tone controls in the Luxman.  The loudness control is also very very good.  Try those and see if you can avoid swapping out more gear.

The best amp I’ve heard with my Harbeth M30s is the Line Magnetic 845ia.  I have some other tube and SS amps here (all more powerful), with separate competent line stage, and still prefer the overall sound of the LM integrated.  I went to hear the Luxman 595 integrated with the Harbeths and on a whim listened to the LM (I’m generally not a tube guy) and preferred the LM.  Definitely worth an audition if you can !  Not sure how it would sound with the C7.

I have used many amps on the Harbeth SHL5 before, currently own the SHL5+ and Luxman L-590AXII, Sonneteer Orton and Naim NAC 282/NAP 250DR. The Naim sounded best with the Harbeth to my ears and preferences. The Harbeth sounds a bit dull, flat and uninspiring with all other amps, including the Luxman. Having said that, I noticed there are few people who matched the Harbeth with Luxman without any issues.

I do not have experience with Unison Unico, LTA or other tube amps with the Harbeth.

FWIW, the Luxman sounds wonderful when matched with Marten Dukes in my main system. In this system, the Naim is outclassed by the Luxman. Synergy (and/or maybe listening preferences) is key.

Good luck with the amp search.

I have LM 805ia with 30.1’s and they are phenomenal.

Ryder- my experience mirrors yours. The bass of the C7 with the (NOW SOLD) 550 AX/II was perfectly fine. Never bloated, yet satisfyingly full. The Luxman never played an offensive note with the C7’s. I can’t share one bad comment about the sound, because I didn’t experience anything negative. The Lux was also never dry sounding, but to my ears nothing special, so I moved on. I don’t know...maybe I just don’t love the C7’s. But it was time to break up that system, and I opted to move the Luxman. I have a history of preferring tubes, even when comparing phono stages. That being said, the Luxman was one of the best solid state amps I’ve heard.
