I should probably clarify what I've been considering:

Speakers:

Axiom M80s (low power or high power, not sure yet)
Axiom M100s
Paradigm Monitor 11 v7
Paradigm Prestige 75f (I can get a good price on these, but it would probably kill off my buying a power amp right now).

I would want to pair these with one of these combos for music 2-channel listening:

- Vintage Sansui G5700 (rated much lower than it's true output
- Older Harmon Kardon receiver (AVR65 from early 90s)
- Older Harmon Kardon AVR65 paired with a power amp (nice option). The amp would likely be the Emotiva XPA2 or XPA3.
- My new Marantz AVR paired with a power amp (slicing and dicing up my movie system to upgrade the overall sound, and also having great music).

I listened to the bookcase Paradigm Prestige units, and they were spectacular. I want towers this time, however, as they are more reflective of the sound I grew up with in the 70s, listening to classic rock on a big 'ol receiver with a big pair of speakers on two channels (sometimes 4 channels).

So... with that in mind, I've narrowed my price range down to the M80s and the amp, or the Paradigms and the amp.
