...there is the 2.5-3.0 db difference between the 3's and 7's, but again, the 550 is very competent powering the latter.

I provide concierge service to CJ and can comment on CJ and Harbeth as well as Unison Research S6. Both great amps and options for you.
I have many clients pairing CJ and Harbeth. It is a stunning combination and one I never get tired of hearing. The Classic 62 and Classic 62SE are the primary amps that I sell that are matched with Harbeth, although recently 2 people went with the CAV 45S2. The CAV 45S2 is basically the Classic 62 with a volume control and 3 inputs. I use one as my daily amp when in the office and can listen to it all day long. I added Sophia Elecrtric EL 34s which took the performance to an entirely new level. Jeff Dorgay at TONE recently did a review of it.
The Unison Research S6 is another sleeper. It sounds wonderful...musical, detailed, engaging. However, it is 35 watts compared to the CJ 60 means you need to select your speakers correctly. But, it also mates well with Harbeth.
There was a post I read that says the magic starts at 507. I can't comment on that, but would not discount the 550.
I was the one who made that comment, and realized that I should have included the 550 in the 'where the magic starts' boundary. I agree that the 550 is significantly better than the 505.
These are all great suggestions (Unison Research, CJ, Luxman 550). At this time, I have to say that the 550 is very enticing (pure Class A).
This said, I don't understand the hangup over 505, the build / layout look very similar to the other Class A/B amps in Luxman lineup, damping factor and voltage are in the same ballpark, until you get to the 509.
