You mentioned a Russian father and if you're looking for a little of that influence, keep in mind Balanced Audio Technology.
BAT gear is built in the US and designed by Victor Khomenko. I use both a BAT tubed pre-amp and solid state power amp. While maybe not as "exquisitely" finished as much of the aforementioned Swiss gear, it is of the highest caliber of build quality and the sound they produce is simply fantastic. Not cheap, but will last a lifetime.
