The best speakers to pair with McIntosh MA7000 ?

As you probably already know, speakers are the most personal choice that you will make for your system, and nobody can make it for you. The good news is that you have a great integrated amp that will really drive almost anything, and drive it very well. Go listen to as many types of speakers as you can, dynamic, planar, horn etc. and see what you fall in love with.

And take your amp with you when you for demo purposes. Sure it weighs a hundred pounts, but if someone wants you buy $10K speakers in this economy I'm sure they'll carry it into the store for you.

ATC 19s or 20s. They will really dig out the detail in your music.

Match the speakers to your room size.

I own the MA6900. Though I have not heard the 7000, I am told it is identical, except for the additional power, more I/O choices, and updated cosmetics. I have paired the MA6900 with several Sonus Fabers to excellent results. I currently own the Grand Pianos (I like a laid back sound). Also worked well with Vienna Accoustics. Pairing the MA6900 as part of a more dynamic system (B&W Mark IIs) worked worked well too. It's a versatile amp. And, because it is a favorite of many stereo stores, you should be able to audition it or the MA6900 with several speakers relatively easily.
