After the success of the smaller Ayon preamplifiers many customers
approached us wishing a modular and upgradeable concept. The new Auris
is such a modular tube pre-amp design and is offered in some varieties:
unbalanced or fully balanced, signature version and Phono MC/MM option
for all varieties. This Reference preamp represents the highest
standard of preamp based on 6H30 design achievement and offers a
holographic soundstage previously unavailable at this price class. The
performance of the Auris is outstanding, transparent and vivid in its
presentation. There is a huge space of the recording environment
reproduced with uncanny realism. The purist 6H30 circuit topology is
using zero dB negative feedback, no buffers and no followers or op amps
are used anywhere in the signal path. Excellence in engineering, a
special tube rectified power supply and super premium components
selection provides a special magic to the reproduction of music. Full-featured class A single-endedtrue balanced triode vacuum tube stereo preamplifierPure vacuum tube-circuit design with single gain stage and incorporates only one coupling capacitor at its output stageVacuum TubesWe
believe that the simplest circuits work best together with the shortest
signal path. The shorter the signal path is, the less possibility of
sonic degradation from various sources, including the wire itself. Even
on the circuit boards, the copper traces are kept to a very minimum
length. The completely redesigned circuit board provides a more
straightforward and direct approach to the signal paths. Signal PathWe

power supplies have been further refined with new components and
enhanced AC line noise filtration. Low noise power transformer, chokes
and filters provide total isolation between the input and output stages
which makes this a pure power source. We also use electrolytic
capacitors with much larger storage capacity to make up for the loss in
filtering when using resistors in lieu of inductors. Tube rectified power supply Superior noise reductionLow noise insulated power transformers Power transformers are excellent damped and RFI/EMI ultra-shieldedInnovative power supply provides a high speed energy delivery on transientsDual choke filtered power supply for 6H30 tubesSeparate and isolated power supplies over each stage of amplificationRegulated DC filament supplies with soft-start power up for extended tube lifeAC power line filter to avoid noise and hash from entering into the unit. High capacitance energy storage. Dual Grounding SystemThe
modification of the grounding topology leads to increased rejection of
noise from the power supply and other areas. The dual grounding topology
used in all of our amplifiers is quite unique to the whole hi-end tube
amplification industry. Such extensive topology provides for quieter
backdrop for which the music can unfold in its entirety. It further
establishes the quick and controlled bass response and the full bodied
expression of the high frequency. The ground leg of the signal has not
been neglected and given meticulous attention in its implementation. The
importance of proper grounding cannot be over emphasized. Central one-point star earth groundingDual grounding system ComponentsThe
type of parts used therefore must have a synergistic relationship to
the circuit they are placed in. It is this relationship of which type of
part to use where, that ranks our products apart from the mass. Mechanical ConstructionThe high grade aluminum chassis
