I know of someone who I consider to be very knowledgeable with regard to music reproducion particularly vinyl playback who has tried the Halcyonic device and the Minus k in addition to several others, and he feels that the Minus k for a lot less money was actualy superior on his turntables.Others have also noted that the Minus k has special qualties on analog. I hope to find out for myself in the future, but the cost of the Halcyonic is a strong deterrent.
