Did some more extensive listening using the Vsonic VSD1S and now I'm thinking the DX50 may just not be for me. For reference I prefer a mid-forward sound signature. Also the main thing I listen for is clarity in vocals. Just not getting it with the DX50. Thought it was just a synergy issue with the re400 but it's not where I want it to be with the VSD1s, although it is improved. I posted up quick impressions after 1 song but it seemed like it was the recording of the song that made it sound good. I listened to several other songs and the vocals sound like they are going through a megaphone or something making it sound slightly unnatural lol. Dang it!
This is the same thing I thought till they burned it totally in, how many hours do you have on them now? Also, I do have my EQ set to classical which I do like a lot and helps in some of the week ness of the player. Also all of my songs on the player are in FLAC. I am referring to the Vsonic VSD1s.
