@kalo86 I don't have the S5, was just going off the listed specs so I can't compare sound quality. I can tell you that the K6 sounds good and has plenty of output power. I've been listening to it at volume setting of 12-15 (maximum is 31) although I've only tested it with low impedance iems.
It has left my X2 sitting in a drawer and the only thing I miss is dedicated volume buttons. I plan on upgrading to something in the near future, possibly the Aigo 108
