OK Bas, you got me! I can give you half of what I promised: the prices. The physical things are still not built yet, because the PC boards aren't yet here. They will arrive this week. Optimism is good, but sometimes it stands in the way of accuracy.
The tentative price list follows. We will rename some of these products shortly, but I think that they are understandable here.
RAKK DAC Kit (requires 12v DC source) $250
12v Minimal Reactance Power Supply Kit $79
Passive Transformer Output Stage Kit $299
Active Differential Tube Output Stage Kit $599
Multi-Minimal Reactance Power Supply Kit (which includes high voltage supply, filament supply and 12v DAC supply for Differential Tube
Output Stage Kit and RAKK DAC Kit) $230
I hope that this gets me off of the hook for a couple of weeks! ;=))

Will the board allow the implementor to power the CS8416 and the DAC chip by separate transformer ?

  Hi Alan,
  The RAKK DAC board has two 12V inputs: one for the DAC analog voltage and the other for all of the other voltages. These two inputs are tied together with a trace on the board so you can use a single supply for both. If you want to use a separate supply for each just cut the trace. If you choose to use a single supply, you should know that all of the other voltage regulators are isolated from the analog voltage regulator by another regulator. The analog regulator is a shunt regulator while the other regulators are series regulators.

Is there a description somewhere - arend-jan 06:04:44 06/23/04 (1)
of the DAC itself? Does it have it's own clock?
Thanks,

  There isn't a description up on the webpage yet. The RAKK DAC recovers the clock from the data transmitted from the CD transport or other digital source using the excellent Cirrus Logic CS8416 input receiver. The RAKK DAC has been designed so that Guido Tent's XO-DAC PLL jitter reduction board can be easily interfaced for reduced jitter. Guido's circuit contains a low-jitter reference clock (see www.tentlabs.com for details). K&K Audio will also sell the XO-DAC as an "anti-jitter upgrade" for $250.

Yes..Kevin...it will ;-)
Thanks for the info!
