I’m personally not a fan of stereo enhancer, but it depends on your material. A lot of the earlier pop music (Beatles, Rolling Stones, Roy Orbison) used very polarised stereo, with all the vocals in one channel and all the instruments in the other. Listen to Roy Orbison’s “I’m Falling” and, if you turn the balance fader all to one channel, you won’t her him singing at all!
In cases like this, less is more.
Similarly, if listening to your station on a car stereo, the driver is already left or right of centre, so boosting the already loud side may make it sound very lop-sided.
