Hello, I'm not an expert and my english is poor.. so, I've listened the new Rega Ear in a shop with this chain:
Cambridge Stream Magic 6 (wav file) -> Rega Ear -> Shure 940 (mine)/Grado 125i/DT 880 (600 ohm)
The sound was very warm, I love it with 940 and 125i (40% volume max) , DT 880 sounded very good too, almost better than my Shure (600 ohm/75% volume max) but was the first time that I heard this headphones so I can't judge how sound in a different amp
Bought it and back home
Plugged to my Desktop pc/foobar/wasapi ->Hiface two -> V-Dac II + Stabilized PSU Zetagi ->Rega Ear->Shure940/Grado Alessandro Ms1i.
The sound changed drastically, cold.. poor bass, poor sound, totally disappointed especially from Ms1i.
All I can say is that this amp don't like V.Dav II, really a wrong wedding. So after five years with this gear is time to change, waiting a Rega Dac for the next week
Ps. there is a youtube video that show this amp with fine Nichicon capacitors, but I've read of a guy that found different and cheap capacitors inside.
