GMA callisto vs vmps rm 30

Do you currently own a pair of Callistos?

Assuming you own the Callistos, are you running a pair of powered subs?

Are what are the rest of the components in your system?

After owning a pair of Callistos, I would not buy another pair of speakers without directly comparing my Callistos (and stands) to their possible replacements. Well, I may move up the GMA line without directly comparing, but not to another speaker line.

Yes i do own the callisto's:
the rest of my system consists a GMA Hammer lite passive subwoofer, powered by a Gallo reference 3 amp, Audio Research LS 2 mk ll preamp, Mc'cormack DNA-125 amp, Rega Saturn cd player, speaker cable Audio Magic Xstreme.

The rest of your system seems solid. However, I still stand by my statement that I would not buy another pair of speakers without directly comparing my Callistos (and stands) to their possible replacements. I was cranking "The Black Parade" last night and absolutely lovin' it.

While I agree to audition any speaker as a VMPS owner and a Callsito auditioner there is no comparison, and there really shouldnt be as the VMPS is a entire different animal with much deeper bass, better dynamics and ofcourse a much larger presentation..I would love a pair of Callisto's but would I trade?....nope.

Agree 100% one should audition the speakers side by side the problem is i can't find any place that carries both and vmps dealers in L,A. area are non existent, a point that i have to make clear is that the callisto's are awsome speakers in every respect except for dynamics, im hoping the vmps matches their superb sound while providing better dynamics, remember my musical taste leans towards hard rock / metal.
