Fantastic DAP, Professional service, very good company to deal with
Enjoying my M6 Ultra very much. It’s gorgeous emerald green is very welcoming.Most iems do fine on low gain, but plenty of power at mid gain for earbuds and high gain for headphones. The sound is very analogue like, with a warm signature and thick relaxed mids. Highs are airy but not fatiguing.
Well made and with an excellent android open operating system, everything works as promised. A real bargain for the quality of build and sound. Highly recommended!
