Tried the X3 out with my T-Peos H-200 and the synergy is better than with the Heir 5.0. I think the Dark/Dark quality is why the Heir works better with LO to the the RSA Intruder where-as the T-Peos sounds just brilliant right out of the X3. Has anyone else made the same observation with the H-200? I am using complt 500's on the t-peos BTW.
Right there with you Zach, got the H200s a few days before the X3. I like them better than my VSonic GR07s and they're right on par with my reshelled TF10s. Like you said, I think that the warm sonic quality of the X3 calms the sibilance of the H200 and works well with an already clean midrange and thick bass.
