Getting SET

My system is sounding pretty nice now. But after listening to some high-quality, low-power high-efficiency systems, I realize that they are capable of reproducing music like nothing else I've been exposed to. So, please help me take the plunge, intelligently.

I have enjoyed listening to Lamm ML2, Wytech Labs, and some home-brew designs, among other SETs. One option is to simply buy a commercial SET that I audition. On the other hand, the idea of building a kit is appealing to me. I think that I would gain alot of enjoyment listening to something I build myself. I might learn something, too! (I do not have experience with DIY, but not afraid to learn).

My question (finally!) to those experienced with SETs: Are the kits comparable in sound quality to the (higher quality) commercial products? If you believe so, can you suggest specific kits, for a newbie to DIY? I have read great things about the DIY HiFi Ladyday and the Wellborne Labs 300b. I know that Bottlehead makes kits, and that there are others. Anybody been down this road care to share their experience?

I realize that we must consider both speakers and amp in this discussion. My current speakers are Nola (Alon) Circes, but I am leaning towards a more SET-friendly custom Edgarhorn. If your amp suggestion has adequate power to drive the Circes, all the better, so that I won't have to change amp and speakers simultaneously. The rest of my system is listed under Ever Evolving, "Seattle Sound".

I listen to mostly classical music of all types (chamber, piano and orchestral), as well as some jazz, blues, and vocals. I mostly listen at moderate levels, but sometimes enjoy listening at loud volume. My dedicated listening room is 18' x 15' x 8'. Thanks for your thoughtful replies.
