I have heard all three of those and own the 926s. IMO, the Revels and the JM Labs are definately more refined than the MA Gold 60s - particularly the soundstage and high frequencies.
As for power consumption, the 926s are pretty darn efficient and will need a lot less power than the Revels. I am very very impressed with my speakers - I auditioned many before choosing the Electra 926 and I have been extremely pleased with my decision since. Let me know if you want any more info. Good luck! Arthur
