Mirage M1 with SET amplifier

@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.

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

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.

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

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.
