High Current SS amps with input impedance = 200K

Tvad,

Any SS Amp recommendations given all this?

This is primarily for the OHM 5s which have a somewhat difficult load, are only 87db efficient and the more juice, the merrier.

Power requirement: 250w/ch minimum doubling into 4, high current.

I'd like to stay under $2500 if possible for now.

Also, logistically, I would prefer to stay away from large heavy, hot running monster amps if possible. I know that limits my options....

"I don't know why Mapman is reluctant to consider ARC recommendations "

Newbee, what gave you that idea?

I'm not. I would assume ARC to be a most reliable source for recommendations regarding their equipment given their considerable history, experience and reputation, and the fact that their unit has been a home run to-date in my system.

Tvad has been around with a lot of different equipment I believe and has a good attention to sound quality and technical details so I do not discount his observations in this area either.

I agree with your point about validity of apples and apples comparisons between amps based solely on input impedance differences as well, but I do not doubt that higher amp input impedances relative to pre-amp output impedance is one (of several) technically sound measurements that one can attempt to optimize along with but not at the expense of others necessarily as well.
