dimitris7 if this is the first week with the system those speakers are going to need SERIOUS run in to completely open up...The Zensors I had didn’t come alive till wayy after 300 hours,sounding as you described,tonally flat & boomy on the bottom.I also recall they sounded best fired straight ahead,no toe in...As for the room first kill any reflections(echo's)...Give everything a good  run in & then re access.
Try Acoustic Sounds HighRes downloads-http://store.acousticsounds.com/cat/365/Digital_Download
or consider getting a Rega or Oppo CD/SACD/BluRay player and try physical media....
I gave up on streaming.  Perhaps it is because I am limited to DSL, no cable where I live.But I get great results downloading torrents, which are free. 
I don't bother with MP3, just download HD, eg flac.Save it all on xternal hard drive.
