Hyperion Sound HPS-938 speakers. There are a lot of better speakers, I'm sure, but Hyperions midrange is to die for. They are also warm sounding with perfectly integrated tweeter. Unfortunately company went out of business for the lack of marketing and dealer base. Good product is only part of success.
End of the line products.
I'm interested in those products that you've found "End of the Line", meaning no reason to keep searching, you've been satisfied with this product for 5 years, and see no reason to keep spending up the equipment ladder. For me, Essence Amethyst speakers, and Essence pre amp and amp now date to the 1990s.
