To this speciﬁcation the new 8300CDQ adds high-quality analogue preamp circuitry, coupled to three stereo pairs of line-level RCA inputs to connect analogue sources. The preamp circuitry is kept as simple as possible using high-quality components to maintain signal purity, with line input signals passing to a precision analogue volume stage. Much eﬀort has gone into the physical layout of the 8300CDQ’s circuitry, protecting the sensitive preamp section from noise interference. Taking it to the next level the 8300CDQ now includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download.
