VANDERSTEEN 2C or CABASSE 321 M3 question

I am moving and have too many speakers.

I don't know which pair to keep. (they both sound good.)

appreciate your input ....Help me decide . 

ALSO...does anyone have the Specs on the Cabasse M3 ?

I know they are 8 OHM's but what is the db sensitivity ?

I would like to use low power tube amps on the Cabasse.

thank you
