I had K/IIs, now have J/IIs, and have looked around a lot for amp recommendations for Snells. There are at least four schools of thought:
(1) a big, powerful amp (Stereophile used VTL tube monoblocks and Krell and Threshold power amps, all over 200 watts, for its review of the Snell K/II);
(2) a small valve amp (this is the Audio Note route; EL34 amps are often recommended on UK forums);
(3) a high quality class D amp (another recommendation I've seen on UK forums);
(4) a solid state integrated (some say that quality is important; some say that any decent amp will do).
FWIW, I use a Naim Nait 5i, so I guess I fall into the last camp. Snells are great speakers, and the Ks are supposed to be better than the K/IIs. My guess is that you'd do well with any good quality amp that fits your budget.
