Don't know the Ayon too well, heard it RMAF, but the Ars is voiced with the Merlins in mind, and given how important the amp/speaker interface is,hard to imagine why they Ayon would be any better matched to the Merlins. The Ayon uses KT-88s? If so, also important to know the Merlins seem to play particularly well with EL-34s. Would be interesting to hear what Bobby thinks of the Ayon, if he has ever heard them (with his speakers).
