After my old avr died I ordered the 604 and it should probally be here tommorrow, but after browsing around I seen that I could get the 703 for about $40 more. I know the 703 has a few more watts, has thx and lacks hdmi but hdmi isnt important to me. The 604 doesnt have pre outs where the 703 does. I have the rt1000i's, cs400i, and fx500i's but dont know if I would be in the market for an amp or not. I ordered from crutchfield so i can return the 604 if need be. I guess I just want to be sure I made the right decision. Any input will be greatly appreciated! Thanx!
