gosh--so few choices below 100K but i'll try:
High Efficiency if you want to try some cool tube flea amps: Avantgarde--definitely a statement speaker i've always wanted to hear
Low Efficiency: I'm with the Rockport crowd--heard some Cygnus at a high end shop in Phoenix and didn't want to leave the store--i could have bought them if i also wanted a divorce....
take the advice to spend some of it on plane tickets to listen to as many as you can
