Hi,
I ordered a DAC on Friday 19.09.14 and sent the money by Direct Bank Transfer.
Unfortunately I discovered that this version does not have the volume control like the Dac+ (the website is a little confusing because the detail text shows tecnical infos of the Dac+ also when you click on the pic of the older DAC). I would like to change the order to the DAC+ and also get the case for it and send the rest of the money.

Could you please contact me by email to sort this out.

Thank you

Patrick W.

  Dear Patrick,
  
  the DAC does not have hardware volume control, but in many cases software volume control works quite well. If you need the DAC or DAC+ depends what Raspberry Pi you have. Do you have an old model B or a new B+?
  For the B+ you will need the + models, but these wont work on the old Raspberry Pi.
  
  Best regards

  Hi Daniel,
  I do have an old Model B and I would like to get the best quality possible WITH some kind of volume control with mpd. For this I would be even willing to get a new Raspi B+ if the quality is better with the new DAC+ (considerung volume handling).
  
  The pi will feed Grundig Active 40 Loudspeaker ( quality Hifi some years ago..) so I think you could hear a diffrence if there is any.
  So what would you say ? Can you hear a difference between mpd volume mixing (DAC) and hardware volume control (DAC+)?
  And does mpd crossfade mode work with the DAC+ ?
  
  thanks

  Dear Patrick,
  
  this is hard to say. In general I recommend to set the amplification in a way that you can run all full level most of the time. But as signal-to-noise ratio is very low (>100dB) for both DACs even reducing the volume on the DAC by 20db is not a problem.
  
  I can't say if crossfade mode works, we never tried this. If it works, it will most likely work with both the DAC and DAC+
  
  Best regards

  ok, so I will stay with the old DAC and use software volume mixing if you say its ok and not much worse than the Hardware volume control of the new DAC+.
  
  probably doesn't matter anyway if I read the discussion here:
  http://www.crazy-audio.com/2014/01/hardware-vs-software-volume-control/
  
  ok so I keep the old order and am happily awaiting its arrival
  
  thanks for the response anyway
