LN32A550 speakers

I will use a car analogy for you. You can sit there and tinker with your car engine and can get some small performance gains out of it, but your stock engine only has so much horsepower. Adding aftermarket parts will get you the biggest gains. I would look at adding some sort of aftermarket speakers. You don't have to go big to get better sound.

Most TV's have crappy speakers - it's a physical limitation of the speaker since very few manufacturers will pay for anything other than treated paper cones, and you only have tiny speakers (if anyone mentions Bose here, they will be disowned)

NOTE: Obviously my analogy was extremely simplified and there are many other ways to get more power in a car, but you get the idea.

Instruction Manual. I, too, have a Samsung & feel they have not dona any particularly good job for user friendliness by, us the American public, by them, a big Korean electronics firm.

It is not entertaining reading, but you do need to apply yourself to get a basic understanding of menu controls. Most TVs have middling to crappy speakers, especially compared to external speakers.

I would not dream of using the built in speaker of my primary TV set. I have a receiver & set of speakers. The cheaper alternative for convenience to to trim costs by using an HTIB (Home Theater In a Box) set. I believe they try to cover too many bases for a very competitive price. I consider them temporary solutions. They typically have some sort of critical compromise as part of the package.

With crappy original speakers, only some sort of external speaker setup is needed for good sound. If willing to go beyond the basics, very nice sound, with speakers that will serve well for decades, can be achieved.
