The Audison Prima APF 8.9bit Forza has been around for a while now. I think it is fair to say that since its launch in January 2019, it has almost become a "go to" product for those wanting Prima quality with more power! Certainly the one fitted to Anthony Yeates' A8 (see article above) benefits massively from the additional grunt. In his case of course, it is not "banging bass" that he was after but pure reproduction of one of the world's wildest and most dynamic acoustic instruments, the pipe organ.
