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.

Jorgjean, you can get a conversion kit to use an external linear power supply for the U1 mini. This will elevate it to a very good streamer.

In stock form it uses an internal switching power supply.

I'm using it with an Uptone JS-2 linear power supply and it sounds fantastic.

I am resurrecting this old thread because I am in the same position,  considering upgrading my streamer (Node2i) and I use a Musical Paradise MP D2 DAC I like a lot.

Jorgjean's response seemed to indicate for Pop and Rock he perhaps liked the Node 2i better? Has anyone else purchased the Lumin U1 Mini as a Node2i upgrade and what has your findings been. Was it worth it. Also,  I am considering another very nice digital transport, the Moon Mind 2, at the same price as the Lumin and made in Canada, 10 year warrantee... nice to support our local economy and easy servicing if required. Any users here?.

I went directly from the Node 2i to the U-1 mini. See my comments above in this thread.

alvinnir2 - I was in the same situation as you but now it’s somewhat changed. I purchased and installed a power board upgrade modification for the Node 2i. My Node 2i can now use a linear power supply but I haven’t done that yet because the upgrade included a MeanWell medical grade SMPS and I’ve been very impressed with the sound quality after the new power board and the SMPS burned-in. It took 100 to 120 hours of audio play time in addition to leaving the Node 2i on 24x7 (i.e., not powered down). I logged the music playtime because I was curious how much burn-in would be required.

 I heard similar improvement as described by people who switched from the Node 2i to the Lumin U1 mini. Better bass definition and much more detail. In addition, I hear much more “fleshiness” between the speakers, better imaging, much improved soundstage depth. It’s definitely not rounded off. In fact, it really needed the burn-in period to sound organic. Bass guitar has an incredible leading edge and cymbals shimmer.

 I’m trying to decide if a Lumin mini would add much more or if I should just get a LPS and call it complete. And then the burn-in required for a LPS. The Sbooster on my DAC took a long time. I couldn’t listen to it for the first 50 hours.  It’s a great product when finally burned-in!

I had the D2 and changed to an Ifi Stream and Topping D70 MQA.

Very happy with the results and if offers far greater flexibility with the dac.

The D2 will not work with Tidal connect.

Id focus on the dac but ensure the streamer will deliver the possibilities you require in terms of streaming services.
