Stereo,
Tough question, there is so much out there used at this price. You are correct that the Bulldogs should be high on your list, they are special, but do need the power which you seem to have, except I'm not familiar with the sound of class D amps. Although I have never heard any of Duke's designs (Audiokinesis) the Jazz modules if available used might be worth looking into. As Duke answered above he used to sell the Bulldogs he would be the one to ask. Another speaker that might meet your requirements could be the Daedalus line, again I have not heard Daedalus but forums suggest they may be to your liking.
Good luck!
Jim
