I'm currently looking for an amp to drive the Beyerdynamics DT880 headphones. The primary candidates I've read up on are the Schiit Valhalla/Lyr, Little Dot Mark III, and the Woo Audio 2/6. I would like some advice/impressions from people who've auditioned or own any of these amps and if possible the headphones as well on how well the combo goes together. Also, if you have any alternate suggestions that you think will definitely be better please tell me as well. If it helps, I'm playing ALAC files from my PC using the HT|Omega Claro Halo sound card as a DAC and I'm looking for an analytical sound with a wide soundstage. Thank you in advance.
