I intend to get either the HifiBerry DAC or Digi. At the momment I am running a Raspberry Debian wheezey as a UPnP Media Renderer using gmrender-resurrect (see http://blog.scphillips.com/2013/07/playing-music-on-a-raspberry-pi-using-upnp-and-dlna-revisited/). I only intend using the device to stream flacs from my NAS.
Works great except the sound from the Raspberry is awful and I have no way of using the HDMI cable with my amplifier. The amplifier is (putting it mildly) not particularly high-end. It's an Andersson R1 (a pretty cheap surround amplifier I picked up - digital sampling frequeny up to 96 kHz/24-Bit, input sensitivity/impedance 22mV/47kOhms, signal-to-noise ratio 95dB). So ... my question is, am I going to get a better sound using the digital conversion of the BerryDAC and connecting via analogue RCA jacks or sending a coaxial from the BerryDigi into the cheap DAC of the amplifier? If this is not the sort of question you can answer please let me know as well. Even if you just have a suggestion I would greatly appreciate it.
Thanks!

HiFiBerry team Hi Nicholas,
that's hard to say. The signal-to-noise ratio of our HiFiBerry DAC is better than the SNR of your amplifier. However, the DAC is only the first stage in your amplifier. If the biggest noise sources of your amplifier is not the DAC, but the amplifier stage, a better DAC might not bring an improvement.
Do you have any sources with 192kHz? In this case, I would go for the DAC. Otherwise, if you use normal 44.1kHz or 48kHz sources and you're happy with the amplifier in general, I would go for the digital connection.
But we would like it, if you buy both ;-)
Best regards

Nicholas Hariades Thanks!
And they will both work out of the packet with the latest Raspberry Debian wheezey? Will I have to set the HifiBerry as the standard audio output in a config file? -
HiFiBerry team You need to update the kernel using the rpi-update command as Raspian distributions often comes with older kernels. After this you must configure the modules in /etc/modules.
These informations can be found here http://www.hifiberry.com/products/dac/hifiberry-dac-software/
