What speakers you're using?
You might spare $3k to two components: electronic crossover(you may get kit or assembled from www.marchandelec.com) and tube amp(OK even with 20Wpc). I'd think of VTL TT25.
I guess you know the proccess that once you've got an electronic crossover, you should remove internal speaker crossover.
In passive bi-amp you may loos tonal balance and get too much extra distortions that are realy audiable and annoying.
