I am skeptical about all the "settings" on new stereo receivers and just want what the sound musicians make without any alterations.
All the settings on new receivers are there for a reason. Your room, furniture, floor, speakers, speaker placement, source, and more will affect the sound. Many of the settings are there so you can counter these affects and more closely approximate "the sound musicians make".
Agreed, the setting can be a bit daunting and complicated to learn. You will see true experts debating various settings in any audio forum because ears are different, preferences are different, and all the conditions above are different.
If your equipment has the settings, you can learn about them and experiment at your own pace and level of desire. But if your equipment doesn't have them, you are stuck w/ whatever "settings" the designers decided to use.
A lot of receivers with the settings have easy shortcuts on the remote, like a blue button for games, a red button for music, a green button for TV.
It's your call. Just be aware that what you don't think you want today, may be exactly what you want tomorrow.
