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

Narrowed down my integrated brand choice to these three.  Looking to spend $7-8k (used or new).  These will power Focal Electra 1028be's for now, with a possible upgrade to something else next year.
I'm familiar with Simaudio, but haven't heard/owned the Hegel or Mark Levinson.
Opening the floodgates for your opinions...
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.
I agree with freediver and mickeyb. I have tested hegel H390, H590, Mark Levinson 8505 and many others manufacturers. Hegel sounds like no soul and mark levinson is thin and laid back sound. Accuphase E-450 or E-470 are very musical and to bright side. You can read my test. Bryston 4B3 was very positive supprise. A lot of body and musical. I ended up to accuphase E-450 and PS Audio DirectStream as DAC.
