I'm getting some weird crackling on my modi setup right now. As I'm listening to music (Macbook->Modi->Powered Monitors), cracks/pops start coming in and gradually grow more and more. I stop the music quick and try different players, same thing. I'm not sure if it's my MacBook being weird or the DAC, but when I play through the headphone output of my MacBook, no crackling.
Crappy USB cable? Any ideas?
Yep - OSX defaults to 24 bit which I verified in the Audio MIDI Setup. I came across a helpful paper at Wadia's website that shows how their digital volume control into a 24 bit dac doesn't result in any lost resolution when attenuating a sample: http://www.wadia.com/technology/technicalpapers/Digital_Volume_Control_2.pdf Makes sense, but how things work elsewhere would perhaps depend on the digital volume implementation?
