Indeed, I have heard of them, supposed to be pretty good! Haven't heard them myself so can't be any help there, but I have talked to one person who uses the SV-226 and says it's a real honey of an amp. I wouldn't be worried about the China thing; I have speakers that are made there and used to have a Cayin tube amp made in China, and the amp never had any issues for the almost 2.5 years I owned it. IMHO as long you're buying from a reputable source and they stand behind their product like AA does, it's worth giving it a shot, especially with their 30 day guarantee. If you try it, let me know what you think, I definitely think it's an interesting amp!
