Designer Notes:
The Au Pre design uses tube rectification and regulation, with two 12AU7s in the gain
stage (this is why it is called AU Pre) and a world class solid-state phono stage.
It’s been almost 30 years since we first developed this 12AU7 preamp circuitry. That first
version was designed for a recording studio in Germany as a contract job – Meeting
strict German specifications and requirements. This preamp is, however, a product of 30
years of subsequent research and development. During that time, the original design
was enhanced on the basis of continuous testing, use and feedback, leading to
improvements to both engineering and design philosophy.
Today, we are pleased to debut the design in its home/hi-fi version -- our
AU Pre.
This is easily our reference and favourite tube preamp for triode and lower powered
tube amps. All the elements and design philosophy are also to unleash the best sound
and characteristics of such power amps. It does its important job of provide more gain
and volume in the most accurate and realistic way without alternated the sound like
most other preamps failed to do so.
The minimal design approach...
