I was recently contacted by the makers of KVgear who specialise in accessories for synths, especially desktop stands.
So if you fancy to support your Super 6 Desktop with a dedicated stand that fits its dimensions, you might be interested in this one: Desktop synth stand, ADJUSTABLE & EXPANDABLE, large, Adapt L1 – KVgear
KVgear also provide a solution for combining a Super 6 keyboard model with a desktop model by means of this gear rail: Gear Rail – KVgear
