Vestax VCI-400 EGE sound problems.

[formasw]

Hello I recently brought a Vestax VCI-400 EGE.
All my music collection is MP3 320KBPS brought from beatport etc.
So I have the following problem: when I play a song it sounds really awful like really low bass/mids/highs or in general really bad sound quality. NOTE: Not to all the songs I get this behavior only for a part of them.
When I run the song through a program like foobar it sounds normal.

So any idea what's the problem?
