There are three different VRDS-Neo transport mechanisms. They are VK-0 (used in the Esoteric P-01), VK-3 and VK-5 (used in the dCS Scarlatti). The latter is optimized for SACD playback. The VK-0 is not used in any other products than the Esoteric P-01 and is the top model. The new Wadia 971 will apparently include a Wadia modified VK-5 and should including the Series 9 decoding computer be a top contender for the very best alongside the other options mentioned.
