I'll add my vote for GR-Research and Madisound.
GR has kits that deliver pretty amazing performance with high quality parts, starting at a few hundred dollars. I've lived with the NX-Oticas for about 16mo now, and I've very impressed with the overall performance. In my fairly large listening room, they deliver a deep, wide soundstage with excellent detail, dynamics and tone.
For a total investment of about $7K (including a pair of 3 driver servo open-baffle subs) and 40-50 hours of time, they deliver the best sound I've had in any system I've owned which have included several Magnepans and Revels (up to the Studios) and Duntech Sovereigns.
My experience with Madisound is pretty dated at this point, but they provided good value and fast shipping. I never had an issue so can't comment on how they deal with problems.
