Hello everyone... I am looking to upgrade my receiver as I am purchasing some new speakers in the near future. Currently I have a Denon AVR-1804 which has been fine, I just want more power for Ascend 340 SE's. I've seen people really speak well of Marantz receivers and Yamaha's but I know virtually nothing about any of their models. I do currently use my receiver with DirecTV, my DVD player, Xbox, and Ipod. I am looking to spend no more than $1000 but I really want something that will bring my new speakers to life. Thanks.
