I've owned several Coda amps over the years and currently own an S12.5, which drives my Jena Labs speakers very well. Really clean and super-transparent, with a touch of warmth that ties the whole package together. Lightning-fast but not overpowering bass as well. An acquaintance of mine has a 15.5 that powers a pair of Legacys, and that combo is magical too.
They're certainly not bargain basement in price, but for what they offer sonically, they're a fabulous value, IMO.
