I picked up a pair of Reference 3.1s on evilBay shortly after Christmas, I'd read lots of reviews but never had the chance to audition them so it was strictly a reputation buy.
I'm not at all disappointed, to say the least. These speakers rock! I was a little apprehensive about buying them since I have a small room(12'x12'x7.5') and the last towers I owned, the DCM Time Wonder III were a little overbearing but I have to say the Gallos work perfectly in the space. They stage wall to wall with an amazing depth, the bass is tight and deep enough for any of the music I listen to(I kept the Gallo CLS 10 sub for movie LFE but turn it off for music) and they can get wife-shoutingly loud without breaking up when I want to crank up the intro in Dire Straits "Money for Nothing", my personal test for dynamic range and percussion. Playing Janis Ian's "Breaking Silence" the bass is heavy where it needs to be, tight and distinct, there's no problem hearing the kick drum and bass as separate instruments.
I'm really happy with the Gallos, last thing I'd heard that could compare was the Infinity Composition FR Preludes back in the mid-90s. I don't spend a lot of time listening to speakers that cost more than my house so my mileage definitely varies, but I'll say for $3K new these speakers are the cat's ass. I got mine for $1800 with the Gallo SA amp, I think they would be hard to beat for the price if you can find them.
Any other AG owners here that want to speak up?
Best,
Bill
