I can`t imagine why the Audion 845 amplifier would`nt be an excellent match with your speaker.
Jeff Day of Positive Feedback online reviewed the Sophia Electric 300b SET amp with this same speaker(he owns it) and found the combination absolutely stunning!This Sophia replaced his prior Leben amplifier(no contest he felt).I would think any 'good' quality 845 or 300b amplifier would be fine driving this speaker.
