I go these together with a Protocol Max DAC. Both are excellent. That Daybreaks are neutral and detailed but fun sounding. I'm fairly new to IEMs and am really impressed with these. I love the tuning and think they represent great value for money. I would have preferred a L/R indicator, but I also appreciate the minimal look. So far they seem great.
I have had various DAC/AMP dongles over the years but this is by far the best I have ever had. The PEQ offers great flexibility when using different IEMs and headphones to adjust the sound to one’s liking. No other DAC/AMP dongle I used before offered such a level of customization. It’s powerful too and sounds amazing.
A fantastic sounding dongle, my favorite so far of all I have sound related, nice work Guys! Would be great next time a version with a screen maybe at least some app to know where the volume is set. :) Also the EQ-ing could be great also in an app maybe.
It's really amazing a piece of kit. I have moondrop Ti, theoretically based on the same chipset, yet this one sounds far superior! I like how detailed, yet well-balanced and neutral it remains. The only downside I see is how hot it gets which implies your battery is being eaten fairly fast.
Delivers on all promises and works flawlessly.
