Karan Acoustics Master Collection LINEa & PSUa

We proudly present the first product from our new 30th Anniversary – Master Collection
range – a state of the art line preamplifier with an outboard power supply unit. We believe
this product truly is our “state of the art statement” as every aspect of it reflects 30 years of
our knowledge, experience and learning about design and manufacturing execution of
uncompromised high-end audio instruments. Our choice of very best passive and active
components is a result of endless subjective evaluations and laboratory measurements.
Many components from reputable manufacturers have been produced to our proprietary
specifications. Particular attention has been given to the topology of printed circuit boards
as that happens to be crucial for the best sound quality. Our printed circuit boards are made
out of very particular isolation raw material with all copper traces having a thickness of
75um (preamplifiers) and 120um (power supply units and amplifiers). We also exceeded all
our previous efforts in the area of design and manufacturing of chassis. In addition to an
exceptional aesthetics, the highest available quality aluminium has been used for best
acoustic properties and least sensitivity to RF and EMF effects to the circuits therein. Not
only, very special components for positioning and placement of PCBs inside the chassis have
been implemented in order to further reduce negative mechanical side effects. This, in turn,
preserves transient speed, energy, clarity, definition, focus, microdynamics, true harmonic
structure of music and overall musicality of the recordings played back. After extensive
evaluations, we chose to use CMS (Critical Mass Systems) CS2 isolation/support feet for all
our Master Collection products. They exhibit a minimal transfer of mechanical and airborne
resonances and feedback to the chassis and electronic circuits inside. Preamplifiers and
power supply units have CS2-1.0 isolation/support feet, while all power amplifier use the
larger CS2-1.5 model. All our components are internally wired with Cardas Audio pure
copper chassis wire. Read more…
