"Where some components seem almost content to let the music happen, the Wadia is committed to delivering every last facet of the performance in a manner that is startlingly vivid... The clever part of the presentation is that it manages to balance this impressive sense of get up and go with a refinement that makes it a very satisfying long-term listen... The di122 is a seriously accomplished performer that needs to be on anyone’s shortlist at the price point." 5 out of 5 stars - Hi-Fi Choice

"Compact enough to operate as headphone amplifier with the computer, but also handsome and powerful enough to deserve a spot next to the stereo in the living room." - HiFi Vision

"Revealed subtle details in the music reminiscent of a product costing much more. This is especially true with high-resolution sources. Sound quality is the di122's greatest strength. You will feel closer to the music." -

The truly exceptional sound quality is facilitated by both balanced and unbalanced variable analog audio outputs, offering premium noise rejection for optimal performance. The Wadia di122 also features a high powered headphone output, making it versatile choice for any listening experience.
