Gallo Ref 3.1 vs PSB Synchrony One

I currently own the Synchrony but recently had a very brief listen to the Ref 3.1 at the RMAF. Can't get the sound out of my mind now and have set up an appointment to audition the Gallos next week.

Anybody have the chance to do a head-to-head? Would love to hear your impressions!

Relevant details: Front end is a PS Audio GCC 100 with a Marantz SACD player. Room is medium sized and typical music is Jazz, classic rock, female vocals.

Thanks!
