After careful consideration I've decided to sell my CA Dacmagic-B. I already own a Beresford Caiman DAC which suits my system better so the Dacmagic is now surplus to requirements. It is in excellent condition and comes complete with a hefty replacement power supply. I'm looking for £155 which also includes insured shipping. I would also consider a swap or part exchange with cash settlement either way for the right power amp :)

The DacMagic features ATF(Adaptive Time Filtering), an up-sampling process developed in
conjunction with Anagram Technologies of Switzerland to intelligently interpolate incoming audio data
(of between 16-24 bits, 32-96kHz) to 24bit/192kHz through the use of a 32bit Texas Instruments DSP
(Digital Signal Processor). The ATF system applies sophisticated polynomial curve-fitting interpolation
to create the extra data points and incorporates a time domain model which adaptively generates the
new data in the temporal domain, dramatically reducing digital jitter, even that present in the input audio.
As with our high-end CD players, our proprietary Dual Differential Virtual Earth Balanced filter topology
is used, configured as a low-order two pole linear-phase Bessel filter to take advantage of the high
sampling rate achieved. Two very high quality Wolfson WM8740 24bit DAC ICs are used in dual
differential mode. Since each channel has its own DAC to process information, completely separate
and symmetrical analog filter circuitry can be implemented. These allow both left- and right-channel
circuitry to operate identically, ensuring the DacMagic delivers fantastic sound-staging and stereoimaging properties.
Two digital inputs are fitted (both featuring S/P DIF and TOSLINK) and allow a wide range of digital
sources to be connected. In addition, a USB input enables the DacMagic to be connected to a PC
and act as a very high quality DAC/Soundcard, offering genuine HiFi-quality playback from your
desktop, media PC, etc. A digital output is fitted which passes through the selected digital source for
recording purposes (no up-sampling performed).
