CHANGING FROM AUDIO RESEARCH TO AUDIO NOTE SYSTEM 

That’s a big change.  I’d be sure about it somehow before committing fully.  Can you keep the old stuff until the new stuff passes the grade?

The AN E's are a copy of the Snell Type E. I have a pair. I don't believe the hype that the AN E's are so great! Certainly not worth the high price! I'll take the 096's any day of the week! 

Just my opinion I've heard 096's, in a Shindo system, not in my own room. They sounded great but I prefer my AN-J's a real sleeper in the AN lineup.

@OP,  I like the rec by Mr. Bourne above.  How possible is it for you to keep two systems or have options open so you can go back and forth?  That may be something you aren't interested though.  

After you audition the Audio Note system IN YOUR ROOM, have your dealer replace your Wilson speakers with the newest Magnepan speakers. Listen again to BOTH sets of HW.

Yes, you may want more booms, so get a sub if you think you need it (older Decca orchestra vinyl could us it).

Listen for a few days with each system.  Bet you keep the Audio Research and buy the Maggies if your room is right and the dealer sets them up correctly.  If he/she doesn't move them until you don't hear speakers, but only music.

THEN you will get it.

Cheers, and happy listening with whatever you end up with.
