Hi Almarg, I anticipated the questions you forwarded. The story of my visits to this dealer, to be honest, encompasses several visits. On one visit, I heard the 600.5 amps driving Apogee Scintillas, actually an even more ravenous ampere pig.
I use to own the Pass X 600 monos which I used driving my Scintillas. The ribbon array of the Full Range is very similar to the Scintillas. I was comparing the sound from the Scintilla powered by the 600.5 and the sound of the Full Range powered by the XA 100.
These Full Range speakers are not stock. They have been structurally reinforced, and the transformer loaded crossover has been chucked for a much simpler one. Ridding the speakers of it's transformer makes the speaker an even more torturous load for any amp. It was simply awe inspiring how a 100 watt amp can push the FRs to shocking loud levels, without any whimper.
Saying all that, I have to confess, the Pass sound from either amp does not approach the performance I enjoy with my class D system. Whereas the Pass 600 bloats the Scintilla's bass, my amps fully rule the Scintilla.
Next time I am there, we will replace the XA with my amps, the Pass XP -20 preanp for my Fire, the SCs for my ribbons, and even swap the sources. This should be fun, and instructive.
