I have`nt heard Audion(good reputation) but have heard the Viva 845 amp and thought it was wonderful.Did`nt hear it with Tannoys but why would`nt they work together? I understand Phaelon`s caution for power concerns but Jeff Day says his 8 watt 300b SET Sophia was the best sound with these speakers he has ever heard. Who knows? You have many good options to consider.
