Sound quality issue. Please Help!

Hi guys,

I am about to go crazy since I cannot find the root cause of this issue:

I have noticed that when I play a couple of my tracks (I am a Producer) through my rx2 or any CDJ the sound quality drops in a way I cannot tolerante anymore haha. I dont know if this is a pioneer/rekordbox issue or it is the track itself.

Before I give you the samples to listen to, I would like to let you know how I recorded this problem child:

Volca bass+Volca sample into Mackie profx12v2 mixer and then, that goes into a Tascam pocketstudio dp008, from where I export my final. Wav master. Then, I import it into audacity to later export it as a 16 bit. Wav final master.

So here you have the track in SoundCloud (which sounds good).

Now you can Listen to the track through a CDJ2000nxs2 in this set https://youtu.be/zl1rLeCleGY at min 35. Also, at 37:20 you can hear how degraded it sounds camparing it to the SoundCloud version.

It is the exact same file. It is very frustaring guys. Any ideas?

Thanks a lot!
