Vandersteen 2CE Signature Speakers

Makes the most sense to me.  I personally upgrade the speakers first.  Then the source and then the amps.  Cords and cables are always last.  That's just me. I purchase the best speakers I can afford.  

+1 for building the system around the loudspeakers.

Work the speakers, setup setup setup !!!!!!!
and the room w modest treatments and then cables.

i actually own a shotgun bi-wire set of the Canare and have used them with Apogee Stage , Cornwalls, Vandersteen 1ci
they are pretty good, especially for the $$$
i am using AQ spades and bananas

slightly bettered by a non DBS now ancient set of AQ shotgun biwire Type 6

The idea that a speaker plays jazz and rock well, but not classical is crazy. The requirements for a loudspeaker for all music is the same: "play it as accurately as possible with as little damage as possible for the money".

I don’t fully agree, because what we want from each are different emotions. I have very (objectively) neutral speakers, which I feel are a little light in the bass for R&R, but perfect for Jazz, Choral, Orchestral and movies (latter with a sub). Listening to R&R, I may turn up the bass. :) Also, at low volumes, they lack detail, so loudness helps. Some speakers may be heavier in the bass, or more U shaped responses making them more suitable.

Still, to the OP’s point, actually that sounds more like electronics. As another mentioned, do think about room treatment. Contact GIK Acoustics for advice and high value products.

Many speakers that do well with rock do not do so with classical .
