I just bought a Yamaha HTR-5560 receiver from Best Buy today since I had a ton of gift cards and got a great open box deal on it. I currently own a technics SA-DX940 that I have had for about 3 years. The technics has done a good job but now I'm craving better sound. I just feel like my technics is a little flat. I guess I'm thinking that the techinics was so cheap that it can't be as good as a yamaha. Will there be a noticeable difference with this Yamaha or am I just wasting my $300 (mostly gift cards) on it? Also, if I want the original sound from the dvd and not have the receiver make any changes to it such as that matrix thing ( which I don't really understand), do I leave the setting to normal? Last question, the rear center channel speaker, should that be a regular satelite speaker or should it be similiar to my front center channel speaker. Thanks in advance for helping out a newbie!
