Received my M21 on the same day my friend sent me Rhapsodio Darker, Cartier dac and pa10.
I am incredibly happy with the M21. Till now I love the features and the smooth UI.
Sound quality is worth the price.
I bought it to use with my D16 and the regular spdif cable didn't work.
4pole coax to 3 pole coax worked like a charm with D16.
Using non over sampling filter.
Dop sounded inferior to D2p for pcm files.
Fiio music - used it for the first time. Didn't find it lacking anything till now.
Build quality his way above the asking price.
Desktop mode didn't had any perceptible change on rhapsodio's darker iem. I think maybe transducers like high impedance headphones will benefit. Will try it with R70X.
Edit: it was my fault, i didn't change the gain to super high after switching the physical button to desktop mode. Will try again and report
Also, Darker is like nothing i have heard before. Will write a review for darker in a couple of weeks.
