Although better than a sound bar

In less: no Bluetooth (which has only relative importance)
In Plus: the TV sound is much improved; we can say that it is not very difficult, but the sound bar could not.

A few notes: the volume is stored in the 20-40 range; below 20, after stopping, it is reset to 20 and above 40, it resets to 40; plugged into the optical socket of the TV, this is not enough: we must go back to 47-50 (50 is the highest); it turns out that the TV's optical jack has a fixed output volume, and therefore too low. So I made an analog connection on the TV's headphone jack, the volume is adjustable by the TV remote.
To use it, I connected the optical tap on the LICO decoder, and in this case, the 20-40 range is sufficient (the optical output of the decoder has also a set volume but much higher than that the TV.)

After placing the subwoofer in a cabinet, where he was a bit muffled, I put it behind the TV and the speakers on either side of the screen and a little forward (a rear position, eg fixed to the wall , forces up the treble, and then it becomes too whistling)
I established the levels of treble and bass 4 to 6 (it depends on the tastes and ears), which is okay with your TV, and perfect for music. (CD and MP3); I quickly got used to the presence of serious, somewhat surprising when we discover them, and the look of the amp.
