I will for sure not get another dongle DAC. I didn't want to have to buy this one but I'm glad I did. Not sure I will buy any more IEMs either, at least for now. What I have is good for on-the-go fun but I think only headphones will get me what I want in my home studio. I have an order in for Ollo S5X and hopefully that will do it so I'm not tempted to spring for Audeze MM-500.
