A few questions:
Which Axiom speaker (M3i vs. M2i) would work best with a sub setup?
Looking for recommendations for a sub that is equally cost effective(?).

Will they perform at the level I hear at local shops?
B&W 600 series / Paradigm Studio 20 / Vienna Haydn type of speakers

Lastly, how will they perform compared to an Energy RC-10?

I am leaning towards a M21 with a good sub.

Equipment: Anthem 200 power-amp with a Carver C-16 pre. I play a wide range of music and still play vinyl.

Thank you for any advise on this subject.....
