hey OP
all you mentioned in your post are exactly what i have heard.
now, there are more nuisances in the music. details that are more clear and distinct
but let me be clear first, 1) that all depends on the quality of the DAC you purchased 2) the synergy of the system.
you have a great dac but the reminder of the system cannot reproduce such detail. then nothing else will happen, a slight improvement maybe ??
OR. the dac you got is not any better.so the results may be marginal. really hard to tell the outcome. I wish all will be good as per your expectations
