I've always been curious to hear the Burson stuff, but no complaints at all with the FA-10! I wrote to them and asked which they would recommend for the most transparency and soundstage, mostly for classical recordings, and they told me to go with the FA-10. The only downside is how huge this amp is...the Soloist 3XP would definitely save some space.
I'm sure the Gustard H20 is all you'll need! And yeah, the V3's seem like they definitely don't need 16 watts per channel
But then again, the V1 or V2 Arya's probably don't need that much either lol
