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?
I see you have the LCD-X too. I was thinking about a Schiit combo for that too.
I loved playing with the Loki in my Schiit stack, but honestly, the RME has everything I want/need.
