TV with better speakers

David, You may need some kind of integrated amplifier or receiver if those audio ouputs are the typical line level outputs. It should work fine otherwise.

If they are tied to the TV's volume control, then you're in business as is...

Some televisions have audio out capabilities that allow you to connect an external speaker to the television's internal amplifiers. The more common audio out is a line level signal that would require additional amplification. The best fidelity will be attained by by-passing as much of the audio electronics in your television as possible and using external amplification. I would recommend that you use powered monitors to add surround capabilities. It will keep your system as simple as possible. Go to a Guitar Center, or similar store, and check out their selection. The brands (KRK, Event, Mackie) aren't well know in audiophile circles, but they are high quality products. A set of $400 (sale price) powered monitors can easily do the job.

BTW, it is my experience that surround sound really dosen't add that much to the movie experience.

As far as SACD is concerned, you have either 2 channel stereo or 5.1 channel surround. The 5 channel outputs on your SACD player are discrete outputs and would require amplification and volume control via a surround pre-amp with 6 discrete inputs. To add only surround speakers and not a center speaker would not work with this format. There is no way to set up an SACD player to work in a 4 channel mode (no center). The only way you could do what you want is to use a surround processor with a Hall or Church type mode that takes a 2 channel input and uses DSP to decode some rear channel info. I wouldn't reccoment this since most of these DSP modes sound anything but natural. Surround sound for music can be great if its engineered and mixed right, but 2 channel SACD is an amazing format and I think anything you would do, short of 5 new speakers and a 5 channel amp/processor, would be counterproductive.
