Hi there guys. As you can see in my title, i have the problem that my smartphone sounds better than my dap. I have an Axon 7 and it sounds a lot better than my Onkyo DP-S1 in balanced-mode. My In-Ears are the ToneKing T88K with MEE Audio MMCX Cable. The Onkyo sounds in balanced-mode thin, harsh and have thin bass. My Axon 7 sound cleaner, have more body and the bass ist really punchy and thicker. Why is that so? Are the ToneKing so sensible, that the balanced-output have problems to drive the iems so well. I have no idea why is that so. When i try the output with a coppercable instead the Mee Audio cable, which have silvercoated cables, the sound is much thicker, cleaner and better. It sounds as good as the Axon 7 but i miss many details and the highs are muffled. What is wrong with my onkyo? Have anyone an idea? Sorry for my bad english.
