PREMIER QUATTRO LINE LEVEL &
MC MOVING COIL PHONO STAGE
2 BOX PRE-AMPLIFIER

Audion Premier Quattro line level with moving coil phono stage 2 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 our 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 2 chassis totally dual-mono construction and the power supplies use only polypropylene capacitors). There are 17 active power supply stages in each mono-block pre-amplifier.

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 2 box Line level buffered pre-amplifier with built in MC moving coil phono stage is a great match with our power amplifiers. Ideally matched with our range of Electron cables. 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. This is an extremely capable pre-amplifier and is a very good match with any of our range of intermediate or high end power amplifiers.

Quality both inside and out

As with all our 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 2 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. We recommend our Electron cables with this set up.
