A real giant killer, Does anyone know where I can get some info on this product? So far search results have been nil.
Thank You For Your Help.
Member "Avivey" has one and loves it. He says it killed his Herron phono stage. Contact him about it. He can give you first hand info on how he likes it.
audioasulum.com forums. I believe Jim Hagerman is a regular poster over there.

Are you interested in the Trumpet or Bugle phone stage?
