Regarding power needs for the Ohms, the question is how loud do you listen?
I'm currently running my Ohm 1000s with a Schiit Aegir amp which is 20 watts/ch at 8 ohms and 40 watts at 4 ohms. (The Ohm 1000s and bigger are 6 ohm speakers.) I am really enjoying this setup -- my prior amp was a Hypex with 150 watts/ch at 8 ohms (and a Bel Canto C5i prior to that) and I like the sound with the Aegir better. HOWEVER, my average max listening level is 85 dB. When I got the Aegir, I actually hooked up a meter to monitor the amp's output while I listened. I use about a quarter of the Aegir's power with peaks going to about half, with no sign of strain.
The catch is, if I listened more loudly, say 90 dB or higher, then I would quickly run out of power. So, if you want to listen at anything near 90 dB or higher, you are going to want an amp with much higher power that also has good current delivery.
