Vote for best US made solid state amp

Let's vote for best solid state amp ,made in US The choices are Spectral,Krell,Jeff Rowland,Pass......
I certainly wouldn't proclaim any amp as "the best" (you know, different strokes for different folks) but I'll tell you one thing,Jeff Rowland Design Group amplifiers are certainly CONTENDERS for the best built, best sounding amplifiers in the U.S. or anywhere else for that matter.
I agree with Jasman. For solid state amplification. Threshold SA series amps, especially the SA/1's mono-blocks; 2 or 3 (Class A). And Pass X xeries amps.
