Karan acoustics pre/power combo for sale

We have a 1 year old Karan acoustics KA L Reference MkIII preamplifier with phono and KA S 600 stereo amplifier for sale.

The units are under 5 year transferable warranty, and they have 4 years left until October 2021 !!!

 

The preamplifier is a two box Karan acoustics statement product with power supply contained in one box and all the sensitive preamplification components in the other.

This particular KA L Reference MKIII has optional MM/MC phono board installed with 0,2mV sensitivity for MC cartridges.

  •  Completely balanced, dual mono circuit topology with no overall feedback
  • All stages are DC coupled and operate in true pure class A
  • Separate power supply
  •  In order to avoid inherent nonlinearities of potentiometers, this preamp uses a four-gang attenuator, with 64 positions, implemented by using highest quality vacuum relays and fixed value 0.1% tolerance metal film resistors
  • Due to high sensitivity to interference of preamplifiers, the power supply has been relegated to a separate case of its own, and has been made ultra stable using four stabilisation levels per channel
  • The preamp is remote controllable for volume only

 

 

The behemoth amplifier, Karan Acoustics KA S 600 weighs over 160 pounds and delivers 1800W per channel into 2 OHM load !!!!

THE ABSOLUTE SOUND’s 2014 OVERALL PRODUCTS OF THE YEAR Berkeley Alpha DAC Reference Series

image

The Berkeley Alpha DAC Reference Series is not only the absolute state of the art in digital-to-analog conversion; it also goes far beyond even this superlative to redefine what’s possible in digital playback.

This is a landmark product in that it crosses a threshold of sound quality and musical expressiveness that renders moot the idea that digital can only aspire to mimic analog rather than offer its own set of virtues.

The Alpha Reference is simply stunning in its ability to render instruments as real- sounding objects in three-dimensional space. This startling quality is made possible not just by the Reference’s spatial precision, but also by the timbral vividness and extraordinarily high resolution of the tiniest micro-details. What’s more, the Reference performs this magic trick on all instruments simultaneously, even in the most dense
and complex passages. This unprecedented (for digital) quality allows the listener to easily follow individual musical lines in a way never before possible from digital. Bass performance is also outstanding,
and different from other DACs. The Alpha Reference’s full-bodied bottom end not only provides a solid tonal foundation; it is also exquisitely textured and nuanced.

Note that the Alpha Reference omits a USB input and DSD decoding by design so as not to compromise performance. To play music from a computer, you’ll need Berkeley’s also-outstanding Alpha USB USB-to-SPDIF converter ($1895). Speaking of which, this USB converter can significantly improve the sound of your existing DAC by isolating the computer from the DAC, receiving USB data with a state- of-the-art interface, and by reclocking the output with high precision.

The Alpha DAC Reference is an unqualified triumph, and an easy choice for The Absolute Sound’s Overall Product of the Year Award. (246)

Avalon Acoustics COMPÁS DIAMOND

COMPÁS DIAMOND 

Inspired by the Rhythmic time signature patterns of flamenco music, the Compás illuminates the fundamental structural elements & impulse in all musical genres. Primarily characterized by its dynamic & percussive rhythms, the Compás delivers a disciplined performance withAvalon_compas-diamond high transient speed & clarity of image definition.

This constant Q design generates critically damped driver resonances from octave to octave throughout the audio spectrum. With a Q of 0.5, ringing & transient smearing is eliminated.
Control networks within the Compás crossover are designed specifically to target high resolution & ambience retrieval under high current conditions. At its heart the Compás’s unique ceramic/honeycomb woofers deliver an authoritative low frequency response with unsurpassed transient accuracy, carefully blending with the highs for a “true to source” sound field reproduction. Proprietary low jitter circuitry clarifies the image boundaries to a high-resolution, suitable for professional monitoring, where microphone placement & phasing are critical.

Utilisation of the same diaphragm materials throughout the array adds to the continuity of harmonic structure in a crisp, seamless musical presentation devoid of stored energy; its rock solid imaging presented with a palpable density through accurate & colourful harmonic structures.
