Well, lack of time has prevented me from doing anything like this. This weekend, I'm climbing into my attic for the umpteenth time to finally install insulation -- the rest of the many weekends was given up to routing wires for a network/cable/phone system and building a platform to be able to have the area underneath the platform with insulation so that I can store boxes/crap up there yet still add to the insulation. I do have a list of things I'd still like to do to my house, but right now I'm burnt out on the house, having spent every weekend for the last 5-6 (or more?) weekend working on it. And a lot of the stuff I still want to do (add recessed lighting in the kitchen and closets) requires attic work. It's cold up there! Also, I'm engaged and spending a ton of money on a house doesn't exactly help pay for the wedding. Of course, neither does buying an amp, but at least with an amp there are few hidden costs -- my last housing project went way, way, way beyond what I expected for costs (and time).
So, I hope to have some time in the near future to build something like the AKSA. I also agree that instructions are very helpful, as the KSA comes basically with none, although there is a ton of material on the DIY site about the KSA -- which is one of the problems, wading through all that material. And, it's good to know that others have compared class A amps to the AKSA. As for machining skills, I have none. I'll likely be asking a lot of questions about that. On the other hand, I have a friend who may be moving back to CT, and he has more machining skills in his pinky than I have in my entire body. He should be able to help me, and may have access to equipment. I'll read the sticky this week about the tour. This amp is mainly for my second system, but if I do build it, I'll compare it with my Jeff Rowland to see which one I like better. That should be an interesting test!
