I went from a Bluesound Node 2 to a Lumin T2 that I got a good deal on used. The difference that I hear is the Lumin presents significantly more detail. Things like the singer’s breath at the end of a line, or the little fret squeaks on a chord change.
From what I’ve read my unit is still in the break in phase, as the previous owner had it in a second system and had 5 hours on it tops. I leave it playing all the time and it now has about 200 hours on it.
I will say in terms of sound characteristics, the Lumin sounds thinner, more clinical, and perhaps a tad brighter. Perhaps things will change with further break in.
The Node on the other hand puts out more bass and has more meat in the mid range. My opinion is the Node is still a fantastic bit of kit and great value for $500.
I don’t think I ever want to spend more than $5k for a streamer. But never say never. I am curious though how my T2 sounds to comparable offerings from Auralic and Aurender.
