John,

I don't think the 787 has a switch for 4 ohm loads (if it does it will be very pleasant news to my ears and wallet). Its only rated down to 6 ohms by Onkyo, and the manual clearly states that running under 6 ohm loads could damage the reciever and invalidate the warranty.

Thanks for the info on the Sony and outlaw stuff, I will definately look into it.
