I'm with you in terms of EQ. Two observations I'd like to share here
1. when talking about EQ, many think the EQ is for the headphones, that maybe true in many cases. But with Susvara, my primary intent of EQing if for my sources, and not the headphones. With good headphones like Susvara, I think we all realize some deficiencies of our sources.
2. I think we all have our own Harman curves and listening habits. If we were to print out my own Harman Curve, it may look rather dumb, but that's still mine own
so my second intent for EQing is to get close to my own "Harman curve" so to speak.
I was planning to get a much more expensive DAC but I think I'm getting used to the RME ADI-2 because the EQ capability
