Is the Mytek Brooklyn Bridge or Lumin D2 good buys in 2021?

As long as Lumin exists in the market then Peter and his team will continue to update the software and be available to assist with questions on multiple forums.  Since their parent company is a big player in the digital tv market in the Far East they are not going anywhere. Of the choices you have on hand the D2 is where I would put my money. The D2 is in fact a second generation device so not really dated. 

Why would Roon in anyway be the answer to his question.  Do the Elac's have their own built in DAC?  IF so you don't need either one but especially not the one running off of  Mconnect as good luck with software support from Mytek.

The D2 is the entry level combo product from one of the long time leaders in the streaming industry who developed and continues to update their product on a regular basis so at least you have software support with a no nonsense design and build. They Mytek because of their use of the "contracted" Mconnect app I wouldn't  touch. So if he bought them to be a Streamer/Dac and he thinks they sound similar then always go with the better homegrown app regardless of the aftermarket apps. I would expect that the streamer guts of the Mytek to be nothing more than the Conversdigital board used by PSA, Ayre and many others. One of the reasons that in the end I steered clear of the Innuos products until their own app is finished and market tested.
