Threshold FET 9 Pre-amp (pre-owned)

  • High-quality vintage pre-amp with a good reputation for sound quality. 
  • Highly acclaimed and dominant in the Hi-end
  • Designed by the genius Nelson Pass
  • Phono input


"I would say that it is a fine and elegant device. It has an engaging sound, and mostly not tiring in long listening sessions. It competes without any doubt with a lot of modern preamplifiers with a price of several thousand dollars that I heard.
