I've used nothing but Ashdown for quite a few years as well, currently using a 180 w 112 EB combo for rehearsing and an ABM 500 Evo II for gigs. I bought the ABM with a matching 410 cab, which was OK, but it sounds vastly better now that I use it through a Barefaced Super Twin (amp is a perfect fit on the cab, too!).
Recently returned the amp to Ashdown for a general service, 2 day turn around and a checkover by the people that put it together in the first place, which I find very reassuring, and not something that many manufacturers can match.
