Sound signature comparison - Streamer/DACs

Run your lumin through your benchmark and what are your experience in the sound? 

gkelley op never mentioned benchmark

The op must be talking about benchmark, he stated overly bright and harsh. That’s benchmark to a t!

Keep the LUMIN D2!  I have a Cambridge Audio CXN V2 with dual Wolfson chips and love the warm, musical and dare say relaxed sound signature. Still plenty of detail and clarity.  The D2 is much higher end and I would imagine far better implementation and parts, so it has to sound much better than the Cambridge Audio.  What’s missing from the D2 that you’re looking for? 

If the OP thinks his LUMIN is ‘warm’ then I would suggest he get out and discover more DAC/Streamers! I would never personally describe the LUMIN products as warm. If anything, they are a little sharp around the edges compared to the Rose RS-150 and certainly compared to Esoteric/TEAC, Holo, Denafrips, etc. I put LUMIN in the same sound signature category as Chord. 

I am just curious.   I would say that I would love to have the option to run optical from my TV to it.  Not a show stopper, but worth a listen.
