Don't buy, distortion worse than anything I've heard. Tried multiple cables and Drop said it would respond in 5-7 days. It's been 10 days and they still haven't. Hoped for better for my first amp/dac guess I'll buy from amazon next time since I can make a no questions asked return.
I'll update if they ever get back with me.
Update: Drop got with me 13 days later and have agreed to a RMA return
Also after leaving the unit on for 24 hours the distortion sounded much better on my Tin T2s but the static was loud when listening to anything quiet and could hear crackling in some songs. For my Koss Porta Pro X however, the distortion was still awful and unusable.
Just happy Drop got back with me
Loving' the new Sennheiser HD 6xx open headphones from Drop. I have a small (but mighty!) sound system in my home office: Aiyima T-10 Headphone pre-amp to Aiyima T9 Pro power amp to Sony SSCS5...
