Description

Introducing perhaps world’s finest Direct Heated Triode Phono Stage, the ALLNIC H-8000. Built to complement our DHT L-8000 line stage and A-10000 DHT amplifiers, this magnificent 2 piece ultra-high performance multi-input phono stage is sure to “Change the Game”

This component, being highly specialized and extraordinary, requires an in depth consultation.

Key Features

  • The H-8000 Phono-stage is transformer coupled, with the exception of the first gain stage, the HL2K tube.
  • No negative feedback design with three gain stages
  • A power supply unit separate from the pure DHT phono-stage itself
  • High quality MC Step-up Transformers with Permalloy cores are used for the H-8000’s dual MC inputs.
  • New vacuum tube damping technology – Allnic Audio’s patented “Absorb GEL tube damper” technology prevents harmful vibrations from reaching the signal / gain tubes and, therefore, prevents micro-phonic noise propagation in the tubes. The Allnic Audio Absorb Gel damper technology effectively solves a problem that plagues most tube amplification systems. Provided other tube components do not introduce micro-phonic noise into your system, with the Absorb Gel damping system, you will enjoy a degree of transparent sound that will surprise and please you.
  • Pure Class A operation
  • Pure balanced operation
  • As are all Allnic Audio products, the H-8000 is fully RoHS (EU Reduction of Hazardous Substances regulation) compliant in construction and materials.
