iFi Audio ZEN Air DAC. ZEN Air dac is a usb dac to connect to computers, phones or ipads and provide better sound quality out to headphones or through line out to a stereo. Similar to ZEN DAC, Air uses the same Burr-Brown dac, top quality new XMOS usb interface and a similar headphone amp to provide great audio quality. Air models are at a lower price due to their polymer housing and the removal of the balanced headphone output.
ZEN Air DAC will pair well with a huge variety of headphones, thanks to its high power output & low/high gain switch. Ideal for many open back headphones, the all analogue XBASS+ feature fills up the sub-bass for a richer feel without changing the sound of the mids.
Pro tip #1: To use with a phone or a ipad as a source - a usb-A to power plug cable is included, you just need to plug it into a usb charger.
Pro Tip #2: A usb-A cable is included - to connect with a newer laptop that only has usb-c, add the usb B-C cable below.
So far I am very pleased, have used this DAC with all my headphones (incl, BT 880 250ohm) and there is enough power and they sound very transparent and true to the headphones natural signature. Works well with a Roon Bridge device attached.
