Tube Monoblocks for JM Labs Electra 927 Be

How much power do I need to run these in a smallish room? Currently I am using a MF A308, about 150w/ch and the volume never gets above 1/4. They are rated at 90db sensitivity, but I have no idea if they have any nasty ranges with low impedence and bad phase shift, i.e., I have seen no curves.

What amps might be good? I have heared that 308b amps are wonderful, but replacing these tubes is very costly. I don't want to by alot more power I dont need, since tube amps cost more per watt. But I want that dimesionality and soundstage. I would probably keeo the A308 for now and use it as a preamp.

90dB sensitivity means nothing for these power suckers.
Powerful VTL amps MB180 or larger are in my mind or you can biamp tube and ss. Also Mesa Baron amp have an ability to drive a difficult loads such as JM Lab Electra.
