Quote: Appreciate all your help in this thread I ended up giving up the Sennheisers for a pair of Grados which worked out great for me. I love the sound from Grados but I did give up quite a bit on comfort. The Sennheisers were a little tight on my head but MUCH more comfortable for longer listening sessions. After reading through some reviews, I think I'm going to revisit the AKG K701's. They blew me away with how they handled female vocals and I get the general impression that the E10 will handle them alright. For now. I've never tried a tube amp and am curious how they pair together. Anyone with recommendations on a $300-400 tube amp that'll make the 701's sing?
