Accuphase DP-570
Accuphase describe the DP-570 in typically understated terms which I’ve religiously copied and pasted below.
In reality, as a DAC with a Melco connected via USB, this thing is utterly marvellous. Well worth it’s price as a high end DAC. It just happens to have full CD and SACD disc replay facilities built in. Subjective build quality is impressive. Beautifully finished, weighs a ton, sounds utterly stellar!
“Equipped with quiet and smooth disc loading, the high rigidity and low center of gravity of the SA-CD/CDdrive vastly improves readability, while the MDS+ type D/A converter with four parallel circuits accurately reads disc information and converts analog signals. It also supports a digital connection with a voicing equalizer and provides a programmable playlist feature that lets you enjoy listening in the order you prefer. Enjoy listening to the DP-570, the next step in the pursuit of the ideal disc playback experience.”

MDS+ type D/A converter with four parallel circuits
The MDS+ (Multiple Delta Sigma+) conversion principle is a revolutionary D/A conversion routing that employs multiple delta-sigma type D/A converters connected in parallel for drastically improved performance. By driving four outputs from a high-performance ES9028PRO DAC chip (ESS Technologies) in parallel, the DP-570 almost doubles (=√4) overall performance for distortion, noise, linearity, and more. Because the improvements provided by the MDS principle are independent of signal frequency and level, output signal noise at very low levels is also minimized, a feat that conventional delta-sigma converters find extremely difficult to achieve.
