in my computer room i have the following system:
bose 301 speaker
sansui 8080 receiver
bang ang olufsen beogram x2 turntable

i think, after reading goodsounds review i'm going to try the m3tise's. will i notice a big difference, with my present system from the bose 301, or should i upgrade to a preamp and amp first?
what are recommended preamp/ amp's for the m3tise's. is the sansui 8080 o.k. for now while i try the new speakers?
also i'm looking into a cd player for this system. i've read a lot about the cal dx-2, (used $250) are there any others in this price range i should audition?
thanks
