I've heard the Luxman 590A and 550A II with Devore 9's and both were great. The 550 is roughly half the price of the 590 (~5K vs. ~10K) and doesn't run nearly as hot (I could have fried an egg on the 590) so that was a plus. I heard the two in different rooms with different cables and front ends, so can't do A/B, but didn't think the 590 was twice as good. I hear the 550's phono stage vs. a simaudio LP 5.3 and the onboard phono heald up very well. It was maybe a touch less authorative in the bass, and the soundstage was a tad smaller over all, but considering you save 1500 on an outboard phono plus a PC and a pair of IC's, it seems an okay trade-off, if you're looking for convenience first. There are a lot of options on the Luxman that allow you to tailor the sound, and I found that very appealing.
I know that abouthifi.com listened to the Luxman 550A II with Proac D18s and found it a very good match. It should have plenty of power for either of your intended speakers. It EASILY drove the Devores.
The problem is that if you've heard a good outboard phono stage, it's hard to find an integrated (or preamp for that matter) that will have a better-sounding onboard stage. The Luxman, so far, is the closest I've come to this. The issue is that the phono stage doesn't have any loading options; it does, however, let you use MC or MM (I think, off hand, MC is 100 ohm and .3mv, so covers a lot of MC).
Some people have liked the Plinius and said it has a good phono section--I didn't find it to be to my liking. The McIntosh 6600 is actually a very good sounding amp, though it get's no press, but its phono stage isn't up to snuff. The Bat is a good amp with a decent phono stage, but I prefer the Luxman.
If you do get an outboard phono stage then maybe take a look at the Pass INT-30A, which I haven't heard but am dying to. I did hear the INT-150 extensively and have heard the 30 amp, and have a feeling the INT-30A will be a nice match, but what do I know! That or Luxman, which I am seriously considering buying.
