I have a Hifiman 601 that I really enjoy. The firmware is v0.06.
It would be great if you that have experiance of the various versions could tell med the differences between them. I have read that the sound and other things can change when you uppgrade ex EQ funktions.
Whats your experience, and what version do you like best?
I am greatful for every tips I can get from you in this matter.
The best to all of you out there :-)
