The Arros are a 4 ohm load - I drove them very nicely with a Naim Nait5 (30 wpc into 8 ohms); I miss that pairing!!! Your room size is very similar to mine.
As long as your amp can pass some current into loads that dip a little below 4 ohms, you'll be fine.
I have not hear the Salks but do hear nice things about them.
