I am thinking about buying a tiny little DAC to replace my not-so-good headphone out on my MacBook. The Dr.Dac Nano / JAVS NanoS comes to mind because it is essentially all I need, USB in/minijack out. No buttons to push, no drivers, no problems. My question is though, do any of you guys know if the volume keys on my keyboard can control the volume on this DAC? I have other DACs in the house, a NAD M51 and a Cambridge DACMagic+ for my two other setups, and those DACs bypass the volume buttons so I have to adjust via the DAC itself (those two are also preamps so maybe thats why). Any help??
