It's very easy to make a mistake with PC's. I wouldn't take a chance and buy one without a demo. If you call The Cable Co., they'll lend you a few so that you can try them in your system first. I've been using them for years, and wouldn't do cables any other way.
Also, it won't be random selection with them. They ask anyone who demo's cables to fill out a form that spells out your likes and dislikes of all the cables you try. The A21 is a very popular amp. They will tell you what cables past customers liked the best on the A21.
