Out of curiosity, what is everyone using for a portable source with your 99s? Have you found that magical synergy? I just picked up an Oriolus ba300s portable tube amp. Pairing it with my Hiby R5. Seriously sweetened my Classics in a very good way.
It made them a little less warm in the mid bass and low mids, and added some awesome extension to the upper mids. Now less dark than straight out of the R5. Gave them some shimmer, sparkle and air. Soundstage and instrument separation has noticeably improved. No bloom and a bit more linear, but still incredibly fun and engaging. They sound like a more resolving, more expensive headphone now imo. But they haven't lost any of that rich and organic tonality that makes what they are.
J'ai beaucoup échangé avec et sans l'ampli, et le ba300s est un excellent compagnon pour les Classics. De plus, ses dimensions correspondent presque exactement à celles du R5, à part environ un demi-pouce de longueur.
