I like. Comfy and sound good. Shows differences between digital formats and differences between my gear I'm listening too that I never noticed before. Stuff downloaded from youtube that somebody recorded with their phone from a crappy record player or sound system still sound bad. Low quality MP3's sound about the same. The FLAC and high quality MP3 on the laptop sounds much clearer than through my speakers.
But the R6 sounds most amazing with the Fiio music player.
Listened to a FLAC of Tabu Ley and Mbilia Bel's English version of "Shauri Yako", a famous song that swept all of Africa (except South Africa where Congolese music was illegal) in the 80's. I could understand all of the lyrics (she doesn't really speak English) for the first time. Also listened to a FLAC of the original N'Timbo Swahili version of "Shauri Yako" that someone recorded off the vinyl. Guitars etc. crisp and clear. Beat the miserably recorded youtube version of it by a mile. Then I listened to Hendix, "Exp" and the rest of Axis Bold As Love.
So yeah. Thank you. Should be perfect for H6. Spending more time with the music player now. And looking for more FLAC's.
