I have the 5000, 2 pin PC. Like all Yammamura products they have a slight bump in the low midrange/upper bass which imparts a mild "chestiness" to vocals and instruments. Depending on your system this may or may not be preferable. At the time, with a solid state system, it made male vocals,cello,acoustic bass sound fabulous. Definately on the warmer side of "neutral". No loss of transparency or dynamics noted. Hope this helps. Enjoy listening.
