Lumin D2 or U1 Mini


I am abot to pull the trigger on either of those 2 units.

Currently I have a Bluesound 2i feeding a Benchmarch DAC3 HGC. Very happy with the sound. As i am having a 2nd Hifi setup (active speakers) I am looking for a second transport.

I had my eyes set on the Lumin U1 Mini. However for a few Dollars more I can get a Lumin D2, which offer a built in DAC and also has a digital output.

What is likely timsound better or is the better propositio? The U1 Mini feeding the Benchmark or the 2.

I listen to Tidal Hifi, iTunes Music, my own Flac Library which sits in a Synology NAS, and I listen a lot to TuneIn Radio.

My Speakers are Dynaudio Sapphire driven by 2 AVM Monoblocks.

Thanks for your valued input.

Benchmark DACs are very good at eliminating jitter and noise from the server/cable, so I hope you tell us if the Lumin makes a noticable improvement in sound.
U1 Mini. More flexibility. Autonomous streamer allows you to upgrade or change out your DAC, or change out your streamer. 

(I run a U1 Mini and really like it. Interface is very good via iPad.)
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. 
Good Point. The D2 also gives you the flexibility as standalone. Or even use the digital out into the Benchmark.  How good is the sound though from the D2? Comparable than running the U1 Mini through the Benchmark? Is DSD capability important in real live?
