This sounds comparable to the FPB and EVO series which were Krell's high end reference models. Anything lower than that like the KAV don't come close.Pretty sure mine is US made but I'll check when I get home.
I'm using an Anthem MCA 20 power amp which doesn't cost much at all. It sounds just as good as my Krell EVO 302e which means either my Yggy or HE-6 is maxed out. Throw the rest of the money on a really good preamp and you're set!
There's a reason I developed the blutack mod in the first place. And initially I had the same feeling as you (wanting more quantity), but the quality increased dramatically. If you want it all, upgrade your gear.
Those are Innersound Eros mk2's driven by an Innersound bass amp and Anthem MCA 20. It's an ESL hybrid created by Roger Sanders over a decade ago. The Krell is still on HE-6 duty as I got no room for now. It will have to wait another year.
