You may want to add Van Alstine amplifiers to your list. Frank has both ss and tube hybrid amplifiers that may fill your needs.Apart from that Wyred 4 Sound gets some very good reviews and you may want to consider them as well.
What about a used Moscode? Here is a 401 for $3500.http://www.audiogon.com/cgi-bin/cls.pl?ampstube&1248109824&/Moscode-401HR---trade-in-refur
