Dolby @640kbps vs DTS @1.5mbit

[Henners]

Hey guys,

As above

What would you say/experience which one has sounded better from the core tracks of the hd audio's?

I've been reading on some wiki & dolby/dts sites.. they both seem to claim they can achieve almost like transparent sound at these bitrates..

I think I can hear a better sound from the DTS side.. even though I know that it is made at like 4db louder.. but it just seems much better clarity

Thanks
