Initial impression:
You will definitely hear that the sound is cleaner with the regen, it eliminates the dirty popping noise that I have with my laptop, bass is more defined, imaging is more realistic, the nuances of the instruments- Damn!!! It is worth the wait and I am just 5 hours into it. Will wait for improvements after a week or a month.
It highlights the capability of your DAC, if you have a detailed DAC, it will be much more detailed but more fluid with the REGEN, but as for me, I have a NOS dac which is not that detailed but is musical enough to satisfy me.
Haappyyy Me!
