Good detail and sound stage. Definite improvement over my Hiby R6 2020.
I loved the M3X (still do), great size/sound and extremely portable so the M6U was the next step up being slightly bigger but still portable. The M6U is another great sounding Shanling player, I stream music via Tidal, Amazon, Spotify and play directly off the SD card. I have used Musicteck a couple of times now when I have needed to upgrade my equipment and I have found them to be price competitive and very speedy with delivery. All in all I have been very happy with my purchase.
Great smooth AKMV sound. Decent battery life
2 things I don't like about this player 1st the display screen look terrible looks like a 480p resolution 2nd the user manual is difficult to figure out. I still don't know how to reset this player.
Really good value for the money. I like the "4 AKM chip" sound and the UI is suprisingly fast. Not too heavy. Very pleased with the M6 Ultra as my portable music player option. Nice job Shanling !
