Hi, I really have to say I'm really speechless what the Chinese have done here. For mobile use, one of the best Headphone Amps! Although not compared with Lake People products, but they are also not available on mobile phones. Home Theater = only Lake Pople !!! Even when I connect my LCD Audeze 2 I get still steaming. Best combination: FiiO 12 with AKG Tiesto 276 = brutally awesome !!!!
