Nothing specific other than I'm enjoying the HD800 right now on the Sophia's. Much more than I did with the the EML's. Warmer sounding with better air up top. Musical even! Yeah, the HD800 can sound musical!
Edited to add: The ATH-W3000ANV also sounds nice on the Sophia's, too. The midrange no longer seems withdrawn as compared to stock tubes. Its soundstage depth sounds extraordinary.
