Magico A3 replacement

You do not list a budget unless I missed it and your room is on the small side.  I recommend either the Vivid Kaya 90 or the better the Vivid Giya G3. I auditioned Wilson’s, Magico’s, Raidho’s, and Focal’s of equivalent price and chose Vivid G3s for their clarity, staging, uniformity from treble to bass, dynamics, and timbre.   Will mate well with the clarity of your Constellation amp that will have no issue driving them.  You need to warm up to their esthetic.  Read pro reviews on either model.  You have courage buying without audition.  Since this is a subjective hobby I always recommend auditioning.

My budget is not much above 10-12 grand used.

I'd treat the room and keep the current speakers.

What a great list!

I plan on keeping it for future reference.

If you like the magic sound of Magico speakers, why not look at moving up the chain to the A5 or the S3?
 

All the best.
