Description
 

<p>It requires electronic circuit design skills, sound quality control and long-term tuning to balance the performance of a headphone amplifier, a DAC and a Pre-amp in one box without any compromise, which is not easy to do. While CMA800i achieves that and perfectly fulfills these three requirements. <br /><br /></p>
<h2>A World Class DAC Section</h2>
<p>With the True DSD technology, CMA800i ensures that the signal processing is done under the original DSD format, strictly following the standard processing of SACD playback. It supports 192KHz/24Bit PCM input and can precisely dig out every single detail in a track. <br /><br /></p>
<h2>IIR Digital Filter</h2>
<p>· Wolfson DAC chip WM8741 brings CMA800i beautiful sound. <br /> · IIR/FIR two switchable digital filters completely eliminate the pre-ring from the impulse wave, producing a more natural sound. <br /> · Independent power supply for DAC section ensures the impressive performance. <br /><br /></p>
<h2>A Wonderful Pre-amp</h2>
<h3>Sound quality, to a great extent, is on the performance of pre-amplifier.</h3>
<p>To achieve the best possible sound quality, CMA800i is designed with a totally independent pre-amplifier served by independent power, supporting RCA (single-ended) and XLR (balanced) inputs. An ALPS27 motor potentiometer is used and it works in analog mode only, supporting remote control. CMA800i is made to explore the ultimate potential of active speakers. <br /><br /> Input and Output Interfaces <br /> Input: SPDIF input and output, USB type B input Analog Output: balanced out (XLR x1 pr) and single-ended out (RCA x1 pr) <br /><br /></p>

<h2>Sophisticated Craft</h2>
<p>CMA800i's chassis is made of aviation aluminum and its cover is only 10mm in thickness. The specially tooled "mutual-bit" structure makes the chassis strong and stable. Each side of CMA800i has balanced weight since its internal weight is evenly planned. CMA800i's feet are made of pure aluminum, helping to avoid resonance. Even every screw is precisely CNC-tooled into "CD texture", giving CMA800i another unique feature. <br /><br /></p>
