xDuoo Link2. What I am hearing is a DAC/Amp that sounds somewhere between the Lotoo PAW S1 and HiBy FC3. This Link2 is the middle ground between the two. It has the smoothness, which is more at home to AKM, and technical competency which is closer to FC3 style. With the wealth of options, we have today, selecting a dongle can be quite a headache and I can personally attest that if I am to compare between this Link2 and Hidizs S9 or Shanling UA2, it will no longer the question of which one offer the best sound quality. It boils down to preference of pairing synergy, features and sound signature. Yet again precisely the Link2 will provide the option between S9 and UA2. Can’t go wrong with any three of those. Link2 exhibited all the top-notch quality that is easy to appreciate.

The biggest X factor to choose Link2 would be the rich feature it provides. The Bass boost option is very useful and probably the only one in the market now with such option. Toggling on the Bass Boost, it does not sound artificial at all and will work wonders on natively thin sounding IEMs or perhaps even emulating the Harman Curve for some. Similarly, the Soundstage toggle will provide realistic change that is not out of place – the presentation takes a step back and immediately the layers are audibly spaced out better. But if you prefer intimacy then just keep the toggle off. Not forgetting that there’s the play and pause button beside the volume adjusters, all these features does really help in real life usage. My only gripe, the volume adjustment should have been independent from the host volume like the Tempotec Sonata BHD or HiBy FC3, but hey I am nitpicking here.


PS: Stellar flexibility between iOS and Android/PC with just an easy swap of the included cables



Recommended Pairing: Anything up to 250Ω
