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 price is 18.000EURO for the combo!


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 !!!!

This is true dual mono amplifier which require TWO power cables.

  • Technical data:

  • 20 ultra fast Sanken RET output power devices per channel, with a total current capability of 400 Amperes;
  • 8 voltage regulation stages;
  • Current feedback topology, with no overall feedback and with only 0.02% Intermodulation distortion (IMD) at rated power output into 8 Ohms;
  • Each channel uses a custom moulded 1,500 VA extremely low noise toroidal transformer and 132.000 µF of total capacitance;
  • Frequency response DC-300kHz +0, -3 dB;
  • S/N ratio better than -112 dB at rated output into 8 Ohms;
  • Damping factor better than 10.000:1 into 8 Ohms, 20Hz-20kHz;
  • Pink noise power output of 600W/1.000/1.800 into 8/4/2 Ohms;
  • Input sensitivity: 2V
  • Net weight 76 kg



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)
