I keep narrowing down my search for a new reciever, and am currently looking at the H/K. I am hoping someone can tell me the difference between these models. I found the AVR320 at J and R for $400, and I found the AVR320-Z at Harmon Audio for $400. My question is, is the Z just because it is refurbished? If not what is the difference? My other question, trying not to call J and R is, what is the difference between the 320 and 325. The 325 has 50W x 7, the 320 has 55W x 5, anything else different? And anyone know the price and availability of the 325, J and R doesn't say much, just gives a number to call and Harman Kardon' website doesn't even have info yet. The other option would be a Marantz SR5200, but the best price I found was $550 at Cambridge Soundworks(www.hifi.com). Does anyone have a better price on the Marantz, I really liked the Marantz when I listened to it, but can't justify the extra money.
