Shahinian and Ohm

I have owned a set of 100 M3 (in M2 cabinets) for 2 1/2 years. In a smalish room 60w RMS is "adequate". They like current, clean of course. I would like to double that. Their rated for 150 max.\

They sound wonderful!

mapman has had a lot of ohm experience, but i'll say any decent amp around a 100 watts will be more than enough power for the 100......the ohm is pretty incredible.

100 watts/ch should work well.

Go for high current, doubling as much as possible from 8 to 4 and 2 ohms for better results and a low end with more weight and balance at lower to moderate listening volumes though.

I've successfully used my 100s with the 70ish watt Prima Luna monos, but prefer my ARC VT130SE which is app 120 watts per. My room is large (app 23' X 14' X 17' ceilings, with a large open space behind the listening position) and I do go pretty loud on occasion. OTOH, I use subs which reduce the main amp's workload. Overall, I'd say 100+ watts is a good idea, but you can certainly get by with less in most rooms.

BTW Shahinian and OHM are both omnidirectional but the drivers and design approach are very different. I think I recall Shahinian uses multiple drivers with variying orientation for a particular frequency range while OHM uses a single omnidirectional Walsh driver for most of the frequency range. A lot of the "coherency" from top to bottom with the OHMs is inherent in the single Walsh driver design approach.
