I've recently been testing the iFi iDSD GR 2 DAC/headphone amplifier, and while it's a perfectly decent performer, it has left a question buzzing inside my mind like a wasp trapped in an upturned glass: why does a DAC need a Bluetooth input?
A seemingly innocuous question, perhaps, but one that won't leave my brain. Let's be clear that the iDSD GR 2 will set you back £529 / $529 / AU$849 at the time of writing, a product that's likely going to be driving all manner of respectable wired headphones.
