Maggie choices help

Ok Here is my system. I said the 2.6 Vs 2.7 because of the last year for Ribbon tweeters in the 2 series. I don't want to spend More then $1500 of speakers leaving out the 3.0 series.

Pre: Adcom GTP 500II
EQ: Lumark 2250 (to get the most out of the speakers)
Amps: 1 NAD 2600A, 1 Nad 2700
CD: Nakamichi CDC3a
Speakers: ADS M12 Towers
Sub: Velodyne ULD 15II

What do you feel is my weakest link needing upgrading? I may next look to buy Maggies and/or try a tube preamp.

You all are terrific! My system has improved thanks to this sight and all you audiofiles help!

Where are you located at in the country. I have a pair of 2.7QR and would be happy to let you come over and hear them.

My opinion is not nearly as worthy as the rest. I have never owned Maggies. With that said, I have always thought every incarnation of the "3" series to be the most compelling.
