Several Axiom owners auditioned both Studio 100's and Axiom M80's including yours truly...not in an A/B test, I should note.
You'll likely find only subtle differences between these two speakers in regards to their sound dynamics....both offer powerfull sound with a very detailed, neutral feel, detailed and crisp high's, clear mids and very deep, punchy bass. Even their freq graphs(found at Soundstage) are quite similar by comparison(at least Studio 100 V3 vs Axiom M80 V2) which isn't too surprising since both companies have a similar design goal in mind. Either would be an excellent choice for music and/or HT use. The Axioms are less expensive, however the price difference narrows a lot if you choose to go with the most expensive of Axiom's custom finishes(high gloss Rosewood, Piano Black).
