ARS SONUM FILARMONIA - QUESTION

I am considering purchasing the new amps coming out soon and I wanted to know how people would describe the sound. I have Cary sixpacs that I like very much with my Merlins (and a Joule LAP 150). How does the Filarmonia compare to the Berning or the Joule Amp? Any comparisons with the Sixpacs or the Cary V12R? Any assistance would be appreciated.
