Topic: which way to go RME HDSPe AIO or Fireface(800 - 400)

Hi:  Looking to upgrade and have decided on an RME product.  If money is not a factor,  will the RME HDSPe give me results that are as good at Fireface stuff?  i know I'm talking broad stroke here, but bottom line, will the finished products be close to each other.  I'm well versed in firewire and PICe technology as well as DAW recording.  Just looking for ballpark comparisons....

thanks a bunch...
Randy
