Well the Corvina is battery powered, I'm just unsure how the tube could react to shocks while heated.
I could stuff it into a backpack...the results are anyway waaaaaaaaaaaaaaaaaaay better than the X7+Se535 so maybe worth the effort.
Oh...just adding that HD800 are open so it's better to travel on a quiet area...
All very good stuff. The Heir 10 is slightly warm and V shaped but well balanced and airy. The Ve6 is much better than on my first try a few years ago they must have changed their demos. Very smooth, spacious, really nice. The Witch Girl Pro was good, nothing special to say, well balanced sound. The Aether was impressive, punchy and detailed and airy. Will have to try again. I lived the PFX tonality but don't know if I can live with the fit.
