Ravi, it's unlikely that you'll find someone who's used a 5730 with that setup. The usual principles apply: unless you play the speakers so loudly that the current draw is excessive and the protective circuits shut the receiver down, everything will be fine. If you do get it, don't set it at 4 ohms; that reduces the maximum voltage available and therefore the maximum current and power.
Unless you'd be getting a real good price on that 5730 you might also consider the Onkyo 504 factory refurb available for about $160U.S. from Shop Onkyo, which is a bit better unit.
