I've never seen or heard Soulution gear in person, but I've been told my Odyssey Khartago Kismet amp is pretty close in sound quality to the Soulution 710 amp. Alon Wolf of Magico actually uses an older version of the standard Khartago (non-Kismet) amp for testing his speakers. The standard Khartago offers up a tad less transparency and is a tad bit warmer.
With the much newer, maxed out Kismet version that I have, I'm sure it gets much much closer to the Soulution 710 at a mere fraction of the $40k cost of the 710.
I have no idea how this really helps at all with this thread, but just thought I'd at least brag about my amp a little since they sound very similar, if not the same with my version.
