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.
