If anyone is in quick need of a ZBIT, and would rather not wait the 4-5 months for a new one, I'm willing to sell them mine.
I'm currently not using it, as my current DAC does not have balanced connections (although it would not surprise me if I needed to buy one again in the next couple of years).
Regardless, in the meantime, mine is available for anyone who needs one more urgently.

It comes with the gold knob, and has the Single Stepped Attenuator upgrade / option.
Also included is a one-meter Better balanced cable (this is the cable recommended by Steve).
New these two items cost $829.
I'm offering mine for $675.

And of course I can ship it straight to Decware if the buyer wants to add  any additional upgrades.

Looks good!
