Single Driver Recommendations + amp Qs, Omega?


Thinking of trying out a pair of Single Driver speakers. Looking for a bookshelf monitor and the Omega Super 3R seemed to pop up quite a bit in some older (5+ yrs.) posts. Looking to find a used pair at $500 or less. Besides the Omega, anything else I should look for? Are there British single driver monitors in this range?

It seemed most were using low output tube amps to drive the Omegas. Can the Omegas or other single driver monitors be driven with a solid state amp? I have a Magnum Audio MF330 Mofset 2x150W amp. Is this amp OK for Omega's or other single driver monitors?

Thanks for the replies. Is there a British Single Driver monitor (~6 inch driver) available?
Rich (Rar1) -- Talked to Louis today regarding the Hoyt-Bedford Type 1. The speakers look fantastic and I'm also tempted and intrigued.
My sister has a set of Omega Super 5XRS driven to great effect by a little 5 watt Almarro 205a amp. 150 watts is way overkill.
I know, the 150W amp is overkill. Now strongly considering the Hoyt-Bedford Type 1 from Louis at Omega Speakers. I will use a 60W Rega Mira integrated amp instead.
Those Hoyt-Bedfords look fantastic. I wish I had another room to try out a pair. Good luck and make sure to give us some feedback!
