I have the Pio 1522 and was lucky to get the Costco deal last year. My friend like the new Marantz SR 5008 but, started looking for a deal on the pio 1522 like me. What would you rather have? He's not sure on speakers yet. He is getting them a couple at a time after the receiver.
I would say the Marantz is very nice but IMO it would have to be unbelieveably good to be better than the Pioneer 1522...I have the 1222 in my main system and no way would I give it up over my 1222...good luck.
