One of the advantages of Outlaw is their 30 day return policy. It gives the consumer the opportunity to try an Outlaw product in their home (where it really matters) with the only real cost being the return shipping. Outlaw will promptly return the purchase price after receiving and checking out any returned items. It would be great if the NAD dealer loaned you a 773 to try at the same time you had a 990/7125 so you could compare in your room. Regardless, have fun putting your system together.
