what are your speaker wattages & there ohms??
I would get the RX-V1900 just to be safe, having that extra power would not hurt on those BIG speakers
I currently have a Samsung 56 In. S5687W DLP HDTV, two floor standing front speakers (custom made) with 15 in. woofers, 8 in. midrange, and tweeters, and two rear floor standing Jensen LS6b speakers (15 in. woofers, 2 midrange, and a tweeter in each.)
The current system is in a large cathedral ceiling room.
I want to replace an older Carver stereo receiver and am looking at the Yamaha RX-V663 receiver. Would this be a good match for my speakers. If not what would you suggest?
