Recommendations on a big 3 way bookshelf - new or vintage - speakers, have stands 17" high


Hello to all...

Interested in getting a new-to-me pair of 3 way big bookshelf speakers.

Have 2way speakers: KEF Q1 and JBL L25; want to hear alittle more depth and definition in bass (without a sub) and abit more high end sparkle...

Have stands 17" high...

Can be vintage or brand new; would prefer mirror images layout; must have bi or tri wire capability...

Can place 24" from back and side walls max...

Considering Dali , Litton  and KEF... Your experienced recommendations?

Also, both de Capo & Focals are 2/way,.. 2/ way vs 3/way is another discussion. Personally I’ve always preferred a quality two-way system
Take a look at the JBL Studio 530. I don't think they'll compete with the above, but worth a look. 
The JBL100 Classic speaker is the most fun sounding 3 way bookshelf speaker I have ever heard. No bi or tri wiring capability though.  Why is that so important?  If you have tri wired cables, you can still use them.
