What do you guys recommend for the Lyr 2 for around 100 bucks a pair? I got a couple of previous version Schiits that were demos in a shop for cheap. They look untouched and don't have much time on them. The Valhalla 2 sounds pretty ok to me with the stock tubes. The Lyr 2 is lifeless with the HD 600 and LCD-2C I tried it with. Music is mostly jazz, funk, and classic rock. I'd like a lively sound with good bass extension but not bloomy, more on the warm side rather than analytical. Thanks.
