Seeking tube amp advice

I'm replacing my Rogue Medusa hybrid amp to return to all tube...Here are my top considered choices ( to be paired with a Rogue RP1 preamp):
I had a trade deal for a couple of Quicksilver Silver 88s, but I've lost touch with the other party...

I know that there are many choices besides these, but I have had some (good) experience with Rogue, and these are all available now on the used market...

Rogue Atlas Magnum
Rogue stereo 90
Rogue ST100
Rogue M150 monoblocks.

My speaker manufacturer suggests about 100wpc.

Thanks...

The manufacturer (Angstrom) recommends a 100 wpc amplifier for the Angstrom Obbligatos...They don't publish efficiency ratings, but, as I remember from a phone call with the maker, they are 91db efficient.

They have a nominal impedance rating of 4 ohms.

@millercarbon.. just spoke with Marc at Angstrom to verify the efficiency rating. He told me that they are rated at about 90db, and he echoed what you had said about using them with a tube amp. He suggested that they would work well with a minimum of 30 wpc, but that 50 wpc would be safer. That does open things up to the Primaluna and Raven, plus the ST100, which is rated for 50 wpc in triode mode. Hmmm. Just when I was almost out of factors and choices to consider. :-)
