I've recently purchased a couple of AVA products and was very impressed with the attention, promptness and sincerity I received when I emailed a question about delivery. I've also been impressed with how some of my recent technical questions were answered in a very thorough way by AVA on this forum. As an old geezer I haven't often experienced this kind of company ethic since the seventies. These days you're lucky to get a reply from most companies and if you do it's days later. As I presently have the set 120 control amp I've seen, and heard the quality of their equipment, and I fear with the new gear on order I may be in danger of turning into a fanboy. Well, I guess this is the right place for it if I do.
