My Quad63s sounded best with the Jadis 80 monos. Second best were the Jadis 200 monos. A bit of overkill though. The dipolar woofer you mention is probably the Gradient63, made in Finland. I drove them with the 60watt Atmas and the active Gradient x-woofer. They blend perfectly with the Quads, though I know that some people here don't believe this. But hearing is believing.
The big Sound Labs sound wonderful with the MA-2 Mk. III, the Atma-Sphere 220 watt OTLs. If you need more power there is nothing better than the VTL Siegfrieds, unless you want to opt for the huge Atma MA-3, which contrary to the above I have no experience with.
I've heard the big Maggies driven by Spectral 360 monos a couple of years ago and liked what I heard.
Everything else I have in mind is only hearsay.
P.S.: What a coincidence: While I was writing the above, Ralph had put in his post. So thinking I was first, I came in second. Actually he has said it all.
