I had been using the iPhone with the Qudelix 5K, or with an apple camera adapter into a iFi DAC 2, into Moondrop Blessing 2 Dusk IEMs, and both (Quedelix and iFi DAC) sounded really good. But then I bought the M6 Ultra (on MusicTek) and it raised the sound quality and enjoyment even further, and by a large margin. So, not trying to 'influence' your decisions, but just wanted to give that bit of insight into the DAP vs iPhone experience. Seeing as I always have my iPhone with me, I will continue to use the Quedelix>Moondrop setup when 'on the go'.
