Not much yet, still playing with setup. Sierras like to be toed in towards listener while Axioms seem better either toed in less or pointing straight ahead. I really need a speaker switch box, going to start another thread on that.

- Sierras sound a bit more neutral (a bit less midrange) but I don't know which is "right"

(but the slightly more forward midrange in the M3s is also something that gets a lot of positive comments re: detail)

- Sierras seem to have a bit more bass but M3s seem to distinguish different bass frequencies more readily

- Sierras hit volume limits at relatively lower level than M3s (surprisingly low on some electronica)

- didn't notice big differences in efficiency

- main thing I noticed about Sierras in comparison with larger speakers was more detail in complex passages (suspected less cabinet vibration but only a guess)... relative to M3s the difference certainly isn't as obvious, may not be there at all

(if I had to use short words I would say that the Sierras sounded more "solid" than the larger speakers but I haven't done enough testing yet to tell if that is still the case vs M3)

(this may be why I have always liked bookshelf speakers on stands - thought it was 2-way vs 3-way crossover but maybe it was small/rigid cabinet)

So far it's turning into one of those "they do sound different but I'm not sure which one I like better" things, but the differences aren't as big as they were between Sierras and larger speakers eg M60s.

EDIT - I was starting to think along the lines of the Sierras sounding a bit "bigger" than the M3s, but after I moved the M3s out to the stands and toed them in a bit more I started getting the same "big" sound from the M3s, at least as close to the same as I could detect when unplugging & moving speakers.

Speaker reviewing is hard, at least doing it well is hard.
