Two affordable suggestions with upgrade paths:
1. New Odyssey Khartago stereo chassis with Kismit upgrade. When funds allow, send it back to Odyssey to convert to more powerful monoblock and buy another one. They have a very affordable upgrade option to support this
2. Buy used older Khartago monoblocks (should be in your budget). When funds allow, send them back to be upgraded to Kismit level.
Both of these options offer gutsy but balanced sounding solid state amps. Good luck with whatever you decide to do.
