Jomionc, I have come upon a tube that just seems to synergize with the DK beautifully and this is it:

It is designated a Valvo, sold to me as a Mullard, but evidently is a Phillips/Amperex according to Tube Classics. All of a sudden there is this deep structured, detailed bass response with neutral and transparent mids and highs. Look for it as a Valvo E188CC.
Here is a German site that features it:

The difference this tube made in my VS-1 was nothing short of amazing.
