USB-DAC VMV D2R VS D400EX Comparison Youtube. Idea of a hybrid successor combining VMV D2R and D400EX by Masahiro Ishizuka, CEO of Aon.

The first two DACs of D400EX are for left and right STEREO, and the third asynchronous DA chip or IC DAC is equipped with the technology that separates digital and analog to reduce noise to the utmost limit and ROHM's flagship DAC IC BD34301EKV is installed in DUAL mode. The D400EX is a USB-DAC equipped with ROHM's flagship DAC IC BD34301EKV in DUAL configuration, and the R26 is a discrete configuration like GUSTARD's R26, which is equipped with technology to reduce noise to the extreme.
