I have the Sennheiser HD600, Neumann NDH-30, Audeze LCD-X.
I use these with my SSL2 hp out, and with Qudelix 5K.
I spoke to someone about my impressions and his first question was: which dac/amp? and when I told, he just winked.
So my question is: is the difference this obvious with a more expensive dac/amp combo? Should I spend another 6-800 euro to get one? Do your headphones open up/perform that much better?
But if amp make any your headphone better, you basically improve anything in your collection. And you also don’t change headphone. You end up with, let’s say HD600, but better than other HD600.
After all, Audiophilia is about small changes meaning much for a person
