I'm Working on a project with several waveshields. Great so far! Thanks for a great product.
My question is regarding the induced noise. I'm starting with 44.1k audio (using the WaveHC library) with negligible noise. Then I'm going from the shield into a class-D, 25Watt amp. Everything works great! So I should just be happy, right?
But there's a bunch of induced noise! I know the files on the card are high signal to noise. So is it coming from the DAC process? the op-amp? I know the DAC is there to stay, but would it help to bypass the op-amp? Is there any other way to get the noise a little lower?
Thanks for any comments!

Re: Waveshield signal flow, signal to noise ratio
the arduino is not a low-noise device, and the DAC is only 12 bits. its not a CD-quality audio player.
