Audio Detail Chela-04 DAC Valve Pre-Amplifier


Colour: Black


Audio Detail's Chela-04 valve pre amplifier with integrated DAC is designed to reproduce the quality and detail of today's high resolution audio recordings. The valve pre-amplifier features 2 Marconi NOS x ECC81, and a 6N1/6N6 or 5922 double triode to give a good gutsy low impedance output suitable for driving even medium or long cable runs. The pre-amplifier has a gain of 12db, with a zero feedback design, therefore avoiding some of the over load situations that occur in many high gain valve and transistor pre amplifiers in the market today. (Although a higher gain can be specified, if requested.)

Offering three analogue inputs and three digital inputs, the Chela-04 is a flexible and desirable pre amplifier to suit most High Fidelity installations. The Pre-amplifier stage has been designed to be as transparent as possible, to avoid colouration of the sound. The pre-amplifier is fully DC coupled and therefore Audio Detail use Audyn output capacitors, for the best sound. A remote volume control is included, with the option of a manual stepped attenuator.

Coupled with a high specification new DAC design, this is a stunning combination offering a new insight into your music! The DAC inputs featured are Optical, Coaxial and finally an Amanero USB for a feed from a dedicated server or laptop etc. All simply selectable from the front panel. Audio Detail keep the pre amp/dac simple, the DAC is fully automatic, simply locking to the fastest frequency it can, just press and select your input. This is a Pre-amplifier and DAC designed with the “KISS” principle! Two separate power supplies keep the voltages clean and very low noise, even the heaters are smoothed DC!

The Chela-04 is available with black or silver front panels.
