Which mode has the best sound effect?

2.0 Stereo is suitable for general household use.

5. 1 or 7. 1 surround sound is suitable for people with special listening rooms. Surround sound requires a very strict listening environment. If there is furniture in the room, there will be no real surround sound, which is noise. (Maybe most people don't know that it's not nice. Only fans with good ears know that the phoneme is wrong, so fans usually choose 2.0 to enjoy music and watch movies. )

The 3D mode requires a 7. 1.4 amplifier, that is, a 1 1 channel amplifier, with 7 speakers on the ground and 4 speakers at the top, which are distributed in the front, back, left and right. A special listening room is also needed to realize 3D panoramic sound effects.

The 3D mode only has a good panoramic effect of watching movies and enjoying music, and the sound quality is not as good as the 2.0 Class A power amplifier.

General surround sound power amplifier, the sound quality is not as good as HiFi power amplifier; Because surround sound has many channels, high cost and some circuits are omitted, the sound quality is almost poor.

Different appreciation requires different choices.
