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?
FWIW my MacBook Air M2 seems to have a more neutral sound with my LCD-X than my Playmate 2 with “vivid” OP amps. Seems the Playmate 2 smoothes the highs and surprisingly also seems to lower the bass volume significantly. Then it seems to widen the “stage” a bit, but that could also be imagined.
