I sold my Ncores to have a little extra money on hand while transitioning into a new job, but will buy more soon.
Meanwhile I've pulled out my modded Virtue Two.2 on ClarityCaps, and instead of putting it on my Maggies, where I know it would lack the ooomph, I put it on a pair of my S1-b's. Powering 4 drivers per bookshelf, after warmup, the Virtue amp has proven to really shine with this speaker, and as an amp, is much more impressive than I remember when comparing Ncores with the Maggies.
I'm using my Astron linear supply, and while the Virtue can't really compete at higher volumes, and does clip, at normal levels, with these speakers, it is definitely an audiophile grade amp, and I actually find myself saying, this is the Virtue? Very nuanced, delicate, dimensional sound. Certainly outclassed by Ncores, but a fine amp and worth the price, if you don't need much power.
I spent about $1000 total on mine with mods and different power supply options, including battery. Which would bring things up even further than the Astron, I'm just to lazy to hook all that up.
