Quartet


Quartet is Stereo Digital Preamplifier, and more. Quartet can be used as a standalone ADC/DAC, a standalone music library and player, a CD player, a DLNA renderer, or playing music from an online streaming service, and of course as a preamplifier. Thanks to Quartet's built in phono preamp, ADCs and storage, it is a one stop solution to digitize and preserve precious vinyls. Quartet body is back with a brushed aluminium front panel either natural or black anodized.
