Don't have a clue about the ACIs, but I own the M20s and love 'em. You can read my review, plus all the hoopla about them in the archives, Stereophile, etc. You can't go wrong with these babies, unless, of course, you put them on crappy monitor stands. The Revel stands are from hunger. Stands are a major extension of a monitor speaker and can make or break your sound. Go to audiopoints.com and check out their Sistrum Monitor Platforms. (you can also read my review) They have another, more costly, (but, even better) pair of monitor platforms that are not on their website, yet. These are the ones I own. Speak to Robert. Great guy. He'll set you free. The M20s, sitting on top of these babies, with the right electronics (hey, don't we always need the right electronics?), are truly amazing. peace, warren
Revel M20 vs New ACI Saphire 3 ?
I am looking at these 2 speakers, unable to audition, I will be using a sub (paradigm servo 15), I am interested in their musical performance mostly, thanks
