I should qualify that I have run my OHMS off two SS amps designed to deliver sound like a tube amp: Carver m4.0t and Tube Audio Design Hibachis. These both sounded Ok but it takes a more highly damped, beefy, high current, low output impedance SS amp to make the OHMs sing best. More watts like that will get you higher SPLs with the Ohms and they do that very well. I have found good quality modern Class D amps tend to do that in smaller more affordable packages and these tend to really get the most possible out of OHM Walsh speakers and that is a lot. You can throw the kitchen sink at them and they will never sound stressed or compressed. Most any amp will run out of gas first.
I use my Ohms in my two larger rooms. I use Bel Canto ref1000m amps 500w/ch into 8 ohms, high current delivery, with my big OHM 5s (12 inch driver with 4 three way level adjustments to tune for use in most any room) and this setup does it all. I use smaller but similar 60 w/ch Bel Canto c5i integrated with my OHM 100s (8" driver). The only limitation there is how loud and dynamic I can go which is still quite up there by most standards but not rock concert or symphony hall level loud like I can in my bigger setup.
