Lumin or Aurender

What's wrong with your Bluesound Node 2i?

I will bet if you do a blind test and compare all three, you might not be able to detect much of a difference.  I would be curious if the dealer told you, you were listening to either the Lumin or Aurender but were in fact listening to the Bluesound Node 2i, what you might say?  I could be wrong because I was not able to hear either the Lumen or Aurender when I purchased my Bluesound Node 2i.  One thing I like about the Bluesound is to be able to listen to the complete unfold of MQA.  Can't understand why I can hear the difference when playing MQA?  Wish I knew more about this.  I certainly do not understand the attraction for vinyl when you can stream hi-res on a streamer and not have to get out of your chair.

I could be wrong

You could be, and most certainly are........

Larry5729,
I have a Bluesound Node 2i in one system. I also have an Aurender N100H and an Auralic Aries G2 in other systems.  For fun, I compared them directly in the same system using the same cables.  While tonally they sound similar, there is a very large difference in spatial perspective and information offered with the better units.  The Aurender is significantly better than the Bluesound.  And, the Aries G2 is again better than the Aurender N100H.  As well they should be for the price differential.  For those who believe bits are bits (suggesting little difference in servers/streamers) and that there are DACs that are generally immune to jitter (as mine is supposed to be), I would say you’re really missing out.  I am now of the opinion that the server/streamer is at least as important and probably more important to sound quality than is the DAC.  

Lumin T2 and Ether Regen will guarantee enjoyment. 
And there is a possibility of an aftermarket external power supply with just a little tweaking. 

Aurender added Tidal MQA support at least a year ago.

I have been using an Aurender A10 since it launched 3 years ago and love it. I chose this model because it has internal storage, a streamer and DAC and so this unit does it all and I do not need to have a computer running anywhere. 

I have just had to use their customer service for a failed screen - and they fixed and shipped it free of charge, even though it is 3 years old.

I think the front end app is a CRITICAL deciding factor. If you do not like the interface your listening pleasure will be impacted. Before I got my Aurender I had a unit from Cary. Their unit itself was great, but their app development effort went into their Android product. The iOS version was extremely poor. I lasted about 4 months before switching to Aurender.
The Conductor app from Aurender is fantastic, but it is ONLY available for iOS devices, specifically the iPad.
