G'day Pete, nice to see you drop by and welcome to SZ!!
Ive had the audya now for over 12 months, in a position like you, i really have to take a leap of faith and ordered one without any knowledge and glad i did. So far ive had no problems but thats maybe perhaps i have not dug deep enough to find its flaws, ive just really been enjoying its BIG Audio Style soundstage which really is incredibly and a thrill to listen to.
Support wise, i find most answers on this forum just like your offerings over at Korg, which I truely appreciate Pete. Also ive spoken directly with AJ regarding the Ajamsonic software today which is very reassuring.. Of course i cannot vouch for all on here.
Yes, it is crazy expensive, but i can appreciate the technology .. Unlike others, so far there is only one audya and like Henni's emphasis on the ajamsonic inclusion it only gets better and better, without have to fork out extra thousands for a new board/upgrade...
Not to say i dont get a thrill out of my other boards, but just playing straight OTB, for a keyboard the audya sounds amazingly real..
Thanks again for everything Pete...
Ky

Ps.. Being a drummer like you Pete, then again audya's biggest asset might not be as crash hot for you -:)
