The search among the great ones - 20k+ speakers

Also, your room and set-up restrictions will have as much to do with choosing a speaker as you will. There is nothing wrong with your question, but with the limited information offered, members can’t really advise you so much as offer you their personal experiences.

Add Tidal and MBL to your list.

Hi,
If you live reasonably close to Nevada, go to True Soundworks and audition the Apogee Divas or Duetta Signatures. It would be well worth the trip. True audio Nirvana--IMO

Elaborating on comments that were made above by Marco (Jax2) and Phaelon, in narrowing down your list of candidates I would encourage you to consider the constraints on amplifier selection that each candidate would represent. For instance a speaker that requires the amplifier to be able to provide high power capability and high current capability, in addition to providing sound quality commensurate with the quality of the speaker, could very conceivably necessitate an amplifier investment comparable to the cost of the speakers, or even more, as well as constraining your ability to change amplifiers in the future.

As an owner of the Daedalus Ulysses speakers that were recommended above by Marco, I can attest to the fact that they are exceptionally versatile in terms of amplifier selection. They represent an easy load by any definition, they don't require a great many watts, but at the same time they can handle large amounts of power if necessary. And they definitely do not have "sharp/ringing highs."

Coincident speakers are another well-regarded brand that comes to mind that provides both high efficiency and benign impedance characteristics.

Good luck in your search.

Melchor, which one or two speakers have you heard in you life that you truly loved, that might help in recommending speakers that might appeal to you based on the kind of sound you like. As a general principle I like the type of speakers that Al likes, at least as a starting point - efficient (89db and higher) and easy to drive with tube amps (smooth impedance characteristics).
