I am selling an Audiolab 8200DQ DAC/preamplifier in silver. Fully functional. Visual condition is practically perfect, it is difficult to find any traces of use. The display backlight is a bit uneven, but it didn't bother me at all. The lower part of the remote control is a bit "sticky". Very interesting and hard-to-find equipment. Equipped with reference 32-bit integrated DAC chip Sabre32 ES9018 from ESS Technology (256 DAC per channel), USB input accepting 24-bit/96kHz signals from PC/MAC/disks/memory, 2 optical inputs, 2 coaxial inputs, optical and coaxial low jitter signal output and 3 analog inputs. Detailed technical data and description of functions can be found in the user manual available at this link (paste the link into your browser): www.audio-supply.com/wp-content/uploads/2015/03/8200DQ-Manual-Eng.pdf Its design is similar to the 8200CDQ model, about which there is more information on the Internet. The set includes a remote control, power cable and original box. SPECS: Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.0025% Output: 2V (Pre out) Digital inputs: coaxial, optical, USB Dimensions: 445 x 74 x 335mm
