Integrated brand choice -- Simaudio, Hegel or Mark Levinson?

Simaudio 600i or 700i

I’m using a Levinson 585 to drive a pair of Focal Kanta 2s.  Very nice combination - pretty neutral, with just a touch of sweetness in the midrange.  What I especially like is that I can listen to and enjoy all my music - even average or somewhat bad recordings are still very enjoyable.  I’m not limited to a few great audiophile recordings.  

Matching with your speakers is most important of all.  I have a Hegel H360 and absolutely love it, matching really well with my Raidho's.  Try to get opinions of those that own Focal's or speakers that you are thinking of upgrading to-- that's my 2 cents.

David Belles has a new integrated amp coming out soon, the Virtuoso (200wpc into 8 ohms). He's getting ready to retire, from what I've heard, and this is supposed to be his swan song. A little over $6000. Might be worth checking out.

Some good suggestions above. My concern is that you may be buying 
in the wrong order if a speaker upgrade is in the offing. Proper synergy
between the amp/speakers is key to good sound. As speakers impact
sound much more than power, I would shop the speaker first.
