GMA Callisto VS. Merlin TSM

I won neither but have heard both at CES- The Callistos in 2005 and the Merlins in 2006. Both are winners. I'd go with the Merlins myself. IMMV.

in a nearfield setting, the merlin mm....otherwise its a toss up

Thanks for the inputs!
I wanted to know if they are categorized as same kind in ways of presentation or not.

i have not heard the merlin, but I do have the Calliso in a nearfield listening position. I love it: the dynamics, the clarity and liquidity of the vocals and wide and deep soundstage. also, there is far more clean and deep bass than i expected from a rather small speaker ( i have them on 24" skylan stands,mass loaded with sand). sorry that i can't do a direct comparison.

I personally don't see how these two speakers can be similar in presentation. GMA uses a 1st order, time and phase aligned crossover network. Merlin uses a 2nd order, non time and phase aligned crossover. Merlin doesn't devulge it's design secrets, but in a thread on Audio Asylum, Bobby from Merlin did say the drivers were wired in phase. If thats true, (and designers feel free to chime in here if i'm wrong), you will have a 3db "suck out" at the x-over point requiring additional crossover parts to "smooth out" Most 2nd order designers choose to wire one driver out of phase to avoid this suck out. Without taking sides on one or the other, I would think these two designs probably would not have the same presentation. They both use good drivers, proper internal bracing, etc. Big difference here is in the crossover used. Hope that helps.
