Thanks. I'm very new to audio but I want to get a DAC for my macbook pro to improve audio quality when listening to mp3s with headphones.
I looked at the cambridge dacmagic, and it seems the usb connection isn't very good, but I've read TOSLINK can be bad, too. I read it's a really good DAC in general, though.
The only DAC I tried was a gamma2 (DIY) kit, which sounded great out of USB, so maybe I'll go for one of those. But in theory it should all be digital, right?
