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?
As long as a DAC is decent it will be okay.
However, the AMP has a ton of more influence.
I just got my first Tube AMP and am Blown away by the sound Difference.
I have highly attuned hearing, according to tests, but to me its an unmistakable difference
