OK, so I have the Pi-DAC+ now.
So far so good but more on that later.
One thing that I have noticed though is that the output level of DSD is a lot lower than other audio types. It also seems that the quality of DSD playback is not a good as my DAC however this is perhaps just because the level is lower and I have to adjust the volume before trying to compare to non-DSD audio.
Has anyone else noticed this?

A quick question.
Can the Pi/Dac+ output a AES signal? I've recently bought a PPM unit that has (as well as audio inputs) XLR AES inputs, just wondering if it can be done, and the best way of going about it?
There are converters but anyone know which is best? In-line or powered types.
What on earth is a PPM unit?Quote:

Are any of you using it with an external DAC? lol... I suppose that would negate the DAC+ card.
So can the PI/DAC+ co-exist producing both analogue (via the DAC+) and digital out (via the RPi)? If so, I'm guessing that it uses a USB port, do I need to switch a port on?
The Pi does not have a SPDIF connection.Quote:

The SPDIF daughterboard fits in the same place the IQAudio DAC+ does, so there's no provision to switch quickly between SPDIF and DAC+ quickly.
You'd have to shut the Pi down and power off to replace the modules during a switch.
What have you got in mind with the peak program meter?
What are you looking to accomplish?
Instead of the Dac+ board you can buy a HiFiBerry Digi+ board, which outputs either toslink or coax spdif. I use one with a Caiman II DAC and it sounds better than the HiFiBerry DAC+, the equivalent of the DAC+ board from IQaudio.
I have just received an IQaudio DAC+ board and am about to compare it to both the Digi+/Caiman II and Dac+ I already have. Whichever sounds best will be staying in my system. :)
Thanks chaps.
What I was thinking of doing was instead of using audio outputs, using SPDIF out for the source signal in to a mixer (but that's later) then the PPM and then in to a Reel to Reel.
I get very good results plugging my DAC output directly into the R to R. Lots of good live stuff on Sky Arts. Some great recordings you can't get any other way.
Where in the chain is the DAC?Quote:

Is there a company out there making a mixer with an integral DAC?
I have an EMU0404 USB ADC/DAC and sometimes I'll take the Toslink connection from my TV and connect it to the EMU.Quote:
