best integrated amp.

You might check out Vinnie Rossi's Lio, which is at the upper end of your range (ok, so a little over), but gets rave reviews.

Krell Vanguard sure is a sweet sounding integrated.

Your buying integrated and dropping 7k! Are you looking for Audiophile reference reproduction or simplicity! My own opinion, and opinions are like belly buttons, everyone has one, but integrated electronics was cost reduction oriented! Provide me more about you and for 7 grand I'll get u a preamp and amp that will blow the socks off anything integrated! Look at Jeff Roland intro amp matched to parasound preamp! Do able for 7k!!!!

I have a PrimaLuna Premium Dialogue HP integrated and love it! It easily drives my DALI Epicon 2 speakers. I don't know how hard the Maggies are to drive, but for the money, the PL is hard to beat.
