GMA Callisto vs Reference 3a De Capo i

Im searching for my next upgrade, thus far my favorite is the Reference 3a de capo i. however when recently auditioning it with solid state equipment (Roksan Candy integrated) it sounded somewhat thin and harsh, i had only previously heard it with tube equipment and loved it.

Just yesterday i read 6moons review of the GMA callisto and was intrigued, particularily by comments made in the interview with the designer where he mentions that speakers featuring only a single capacitor as a crossover (like the de-capos) can cause a thin brittle sound with solid state amps due to the load they present...could the sound i was hearing that day be the result of the speakers design?

It seems that the Callisto rectifies any potential problems the decapo may have...cabinet resonances... it is even more time and phase coherant, and still retains a remarkably simple crossover...and they cost about the same.

only problem is no way to audition one, so any comments from people with experience of both?
