New Delos cart

I just mounted my new Delos cart on my new VPI Scoutmaster II. The cart sounds a little bright and more forward compared to what I'm used to. Will this brightness subside over time, or is that the way this cart will sound? If it will essentially stay the same, does it's more sophisticated brothers (Kelos/Skala) have a more mellow sound? All I have read says the Delos sounds as good or better than it's more expensive counterparts.
