I wanted to be a beta tester of AirLens for the longest time, but then I got on a different streaming train. The waiting was too long.
But Airlens will be a winner if it provides SQ advantage over other similar priced (or higher) streamers out there. For people who use PSA DAC with the I2S input, it makes great sense to use AirLens. So far I do not see any negative post yet.
