Mirage M1 with SET amplifier

No, they need some grunt/power, a good push pull tube at >50watts with good output transformer low output impedance to control the bass, because they do go down quite low in frequency response.

Would work. All you have to do is use them as headphones.

An unlikely pairing but in a small room and at low volumes it could be listenable. If you love the M-1 you should get a more appropriate amp however, a higher powered pushpull amp might work.

As you can see while needing watts >50w+) for their low efficiency, they don’t need an amp with brute current because they are a relatively easy drive load even for a PP tube.

Stereophile:
Overall, the M-1 should be relatively easy to drive, though the droop in the top octave would suggest that low-powered tube amplifiers should probably be best avoided.
This speaker will certainly give a pretty full measure of low bass, as can be seen from the in-room, spatially averaged, 1/3-octave response https://www.stereophile.com/images/archivesart/mirMir1fig2.jpg
All in all, I would agree with LA’s conclusion that the M-1 is an exceptionally well-balanced design.—John Atkinson

@donpen21, 
I own a 300b SET and understand your interest. 
No doubt the Tamura output transformer is very high quality. 
I have to agree with other posters here that this is Not a particularly good pairing. To drive an 83 db sensitivity speaker is asking a lot from an 8 watt SET amplifier (Even a superb one).

As Jond said, in a small room playing at modest volume levels you would likely achieve "listenable " results but not the best results. Individually the speaker and SET amplifier could very well be excellent, but not as a match. Each deserves a more suitable partner.
