Hello all!

First congratulations on launching the preorders for the Digi :)

I'm pre-ordering mine today but of course it comes with a lot of questions:
- What's the increased height compared to a berbone Raspberry B ? (height above the 2 USB connectors & LAN port). Basically I need to find a hackable pi case that will fit the 2 connectors with a little driling.
- I hear it works well with RaspFy, what about Raspbmc ? I would love to turn a regular Raspbmc into an almost-fy by tinkering with it :)
- About the clock : have you thought about using one of those high-end TCXO clock instead of a regular quartz ? If yes, then why did it not end up in the final product ?
- Do you have an estimated shipping ? (couldn't find any :) )

Thanks for your product!

Cheers,

Olivier

  - Additional height with the connectors is about 13mm
  - We're working together with the Raspbmc developer, but we cannot say, when it will be supported there
  - We think, the quarz is good enough for the SPDIF output. Looking at the oscilloscope, the biggest source of jitter is the optical interface. And even there, only 192kHz are really problematic. Using special high-end oscillators would have increased costs a lot. Also the supply of these devices is often limited. we wanted to use parts where a stable supply is guaranteed.
  - Expected shipping is mid of february

  Thanks for your answers.
  So I guess only the board itself will fit in a standard case and the connectors will require holes to the upper side of the case.

  Hi Daniel
  
  Also very interested in the Hifiberry Digi and will be placing an order.
  
  One thing though: I can't work out whether the board will come automatically with the header pins and the nylon spacer and screw.
  
  If not, could you possibly list them as a standard costed add-in option on your web site as presumably most people will want them? :-)
  
  Thanks

  @Olivier: Even the board might not fit in a standard case as the crystal also needs a few mm space.
  
  @Richard: the normal headers are included (and already soldered) for the Digi. Customers ordering the additional stackable headers will get a Digi board without the headers soldered.
  The Nylon spacer is not part of the standard package. I will try to clarify these things in the next time.

  Can you please confirm that thé nylon spacer is not strictly needed?

  The spacer it is not needed. However, we recommend a good mechanical connection of the Raspberry Pi and the DAC. Make sure, that the output connectors do not touch the electrolytic capacitor on the Raspberry Pi. You can also use a normal 3mm screw and some nuts. This will also work fine.

  Daniel,
  
  Since orders will not be delivered untill next month, how can I add a spacer to my order, please ? (I guess/hope it's not too late).
  
  Ps: also, please move this topic to the HifiBerry Digi part of the forum, if you feel it should.
  
  Kind regards,
  
  Olivier
