Searching for the most "accurate" speaker (below 15K)

Regarding the GoldenEar Reference, it happens that I own the Triton One and I do respect the brand a lot. But the fact is that, as I've improved the electronics their limitations became evident. Also I need a speakers who interacts less with my smallish room (and the GoldenEars do interact a lot)

This is a very fair statement on your part @vermeer 

I'm curious if you would/could share what exactly you felt the limitations were as you improved electronics.

Active ATC are slightly better than passive. KEF or TAD is a good choice too. 

I like the Harbeth mid and the Millenium Excel tweeter they use - among the best mid range. Their thin walled cabinets means the bass is somewhat of a matter of taste - great classic FM radio sound but not great cranked up with rock or large orchestral or big band. If you live in a condo you can't play loud anyway which makes a Harbeth a great choice.

Not any of the conventional box speakers I know of though so many do sound very good.

Take a listen to OHM Walsh.  Maybe just maybe.   At least for me.

The Vandersteen Quatro Wood CT is right at your price point. A very, very good sounding speaker. Has active
drivers. That would be my choice...

For your budget, used Raidho may worth your consideration.
