Searching for an amp to pair with Rockport Atria II

something with a  lot of juice. The big Pass amps, or the VTL Siegfrieds come to mind.

@creditingkarma, If you want the best performance out of those speakers you buy mono amps and put then behind the speakers keeping the speaker wires as short as you can. Use Kimber Kable 12Tc. It has the lowest inductance of any cable on the market and at 3 feet it will be like having no cable at all. Then get yourself a pair of Parasound JC 1+. You will have to spend serious money to get better amps if you can find a better amp. John Curl knows what he is doing. More so perhaps than even Nelson Pass. The only reason that these amps cost less is that they are made is a high production facility in Taiwan that has all the robots and machines needed to speed things up and do surface mounted boards and such. Small American manufacturers do not have enough money to buy that kind of equipment, They either out source it or do though hole boards by hand. Atma-sphere does Point to point wiring only which I have to admit is a thing to behold. Anyway, the JC +1 uses extremely high quality parts as good as any amp made, the only difference is labor and volume. Parasound will move a lot more of these than Boulder will move it's entire line. I have the older JC1's and could not be happier. They run circles around all the other amps I have had including my old Krells. The JC1+ is even bigger and better.   

Tough to drive, but great speakers. A pair on Ampzillas will sound excellent on them, talk to Underwood Hifi. Beat Pass X350.8 and some others for me.

Boulder amplification goes extremely well with Rockport, Nagra as well.

Thank you for all of the input on amps. I am picking up a pair of Octave MRE220. I really liked the sound of the re320 without the preamp in the system just being feed from my Bartok. The mono put out 220w with 300w of peak power so they will power the Atria well for my listening habits. I will update with my thoughts on the pairing here.
