AUDION PREMIER QUATTRO FOUR-BOX. by Audion

Of all the components that I have owned in the past that I regret selling this is the component that I missed the most. I am now a proud dealer of this product that has had significant improvements over the years and has held on to its position as the best preamp in the world.

The Audion top-of-the-line, line level with moving coil phono stage 4 box mono-block pre-amplifier is totally hard wired point to point and hand built using solid 5 * 9’s silver wire in all its audio path and specially selected and matched components to make it one of the best sounding preamps in the world! Featuring Audion's special unity gain, zero gain stage technology. Audion Premier Quattro line level preamplifier is available in our Uni-chassis’, and includes an MC stage for even the most sensitive of cartridges, it is a true high-end, high quality product capable of handling a massive array of sources.

There are 4 line level inputs and an MC input. The Audion Quattro preamplifier is the finest stock preamplifier ever made according to reviewers. It has the benefits of both simplicity of design and superb execution.

4 chassis totally dual-mono construction
Power supplies use only polypropylene capacitors
Only 4 tubes in the entire signal path from the cartridge
21 active power supply stages.
Transformer-less design
Direct cathode coupled with no input, interstage or output wound components making cartridge matching completely automatic
Extremely fast and capable of handling the most intricate and detailed passages of music.
Outstanding performance, lightning quick response curves and terrific transparency.
We would recommend only two upgrades to this pre-amp, and upon Arthur Salvatore’s recommendation we would advise customers purchasing this to include Teflon V-caps and either Vishay Dale stepped attenuators or Goldpoint or our newest which is a precision enclosed stepped attenuator.

The 4 box Audion Quattro pre-amp uses NOS Russian 6H23N tubes as standard, it also has a ground lift switch at the rear to assist in resolving grounding issues by floating the ground internally above mains ground.

Each Quattro 4-box is so complex and intricate it takes a full 2 weeks to build a set.

Components of the Audion components:
Transformers and chokes are design and handmade by Audion: Mains, chokes and output transformers.
Superior quality parts sourced from Europe or the US. Even the capacitors are made to Audion’s exacting specifications.
Chassis’ are finished in-house which includes powder coating and electroplating to ensure quality.
Special voicing of Audion amplifiers requires every part be meticulously designed to meet their standards.
Every component is hand built usually point to point. Once burned in they listen again in case they are not satisfied before releasing each unit.
