Get Lumin D2. If you listen to Tidal Hifi, D2 will give you full MQA unfolding.... your Benchmark DAC3 HGC is pretty good DAC, but it won’t unfold Tidal MQA.... U1 is only transport streamer so you will need external MQA DAC with it in case to decode Tidal HiFi..... D2 has that MQA DAC on board already.
