Each person definitely has their own preferences. And to me my audio mood swings from month to month - not so much of a new toy syndrome but more like a cyclic routine. I have certain months where I prefer my SR-009 to my TH-900 but in other months the TH-900 over the Stax. And recently with the ADs over the TH-900s but the some days the the Stax over the ADs. i.e. there is no consistency, nor no pattern. It really all depends on at minimum the following variables :-
- what music am I listening to
- what headphone signature am I bored with
- how do I actually feel at that particular moment
Some aspects though I tend be more consistent. The Rox signature never agreed with me and I did try hard to like it. Similarly with the Audezes, I've always been fascinated with their popularity however each time I try (and I've tried the LCD2R2, LCD3, LCD-XC, and briefly LCD-X) it simply didn't appeal to me.
But I do cycle between the SR-009<->AD<->TH-900s regularly.
