You can't go wrong with RX6s. I have the RS6s and love them. They are easy to drive and sound exquisite. Mind you, I prefer the Rs6 over the Rx6s.
The Creek should be a fine match to drive them in your room. I have driven mine with a 35W Marantz PM5003 with no real issue and currently their being driven by a pair of 40W tube mono blocks. So 85W at 8ohm should be more than sufficient for your needs.
The only issue you may have is a tinge of brightness, but that can easily be managed through other means if it occurs.
