Be sure to check out the requirements to drive the speakers you've chosen to pursue. It would be a sad day to find 4-ohm rated speakers and then blow a receiver/amp that can only drive 8-ohm rated speakers with success.
Then again, most receivers can handle a 4-ohm load with success...
I've not heard either set and nothing to add except other speaker brands to check out (I like mine.). Good luck!
