Audion Premier Quattro 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 core 5 * 9’s silver wire in all its
audio path and specially selected and matched components including some
tanatalum resistors, etc etc  to make it one of the best sounding
preamps in the world!.. The chassis’ are black powder coated aluminum as
is the transformer cover. The top plate and badge are mirror finished
stainless steel. Arguably the finest stock pre_amplifier in the world

The Quattro is available in a unique all aluminium
Uni-chassis’, and includes an MC stage designed for use with 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 is the finest stock
preamplifier ever made. It has the benefits of both simplicity of
design and superb execution (with only 4 tubes in the entire signal
path from the cartridge, a 4 chassis totally dual-mono construction and
the power supplies use only polypropylene capacitors). There are 21
active power supply stages in each mono-block pre-amplifier, the power
supplies have their own boxes which makes the entire pre-amplifier
quieter. As all the components are separate all crosstalk is avoided..

The soundstage is extremely fluid and controlled. Roll off in both
directions is seamless. Resolution is astounding, with absolutely
convincing depth even at very low playing levels. It brings recording to
life and places you directly in front of the performance. The phono
stage is of a step ip transformer less design, meaning it is incredibly
fast and fluid.

Amplifier matching

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.

This Premier Quattro 4 box Line level buffered
pre-amplifier with built in MC moving coil phono stage is a great match
with Audion power amplifiers.Upgrade options are available for this model, however
only 2 are recommended ( V-CAPS & a good quality stepped attenuator
like the Vishay Dale or Goldpoint) see upgrade options at end.

Quality both inside and out

As with all Audion pre-amps, they feature a transformer less
design direct cathode coupled with no input, inter stage or output
wound components making this pre-amp extremely fast and capable of
handling the most intricate and detailed passages of music that can be
shown them. Outstanding performance, lightning quick response curves
and terrific transparency

The Quattro 4 box line / phono pre-amp uses 4 x NOS Russian
6H23N 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.
