Most speakers offered in high end shops have merits; you could start by perusing the audiophile brick and mortar sites to gather some brands to consider.
You may wish to spend the money to go to an audio show; while not a perfect auditioning environment, it will expose you to many fine speakers.
Note there are many designs which are esoteric, fine for specific music genres but limited in performance parameters, i.e. single driver high efficiency speakers. Blindly buying a particular technology might bring disappointment, so some education is in order. You would do well to get an informal familiarity with the different technologies employed as well, such as panel, horn, hybrid etc. There are fantastic examples in speakers in all these categories, as well as both ported and sealed subwoofers.
Everyone has their favorite horse in the race, so be prepared to hear a lot of recommendations from fervent owners, and a few proprietors, perhaps.
