A lot of the too-much or too-little bass issue will depend on your reference point. If you listen to live acoustic music, it is very easy for a home system with a sub to have too much.
For example, I attend a large cathedral church and often sit about 15' from the organist's position in the sanctuary. This organ has 118 ranks with five 32' stops and 7,621 pipes in the church. While it can put out deep and powerful bass, it is nothing like the bass I hear from subwoofers. Same thing with symphony orchestras and jazz with acoustic bass if you are listening from a normal audience position.
On the other hand, if one listens to a lot of electronically amplified music, one has a totally different thing going and a sub may be quite helpful in giving you that concert experience.
However, only you can decide what stereo components do the best job of delivering the sonic info YOU need to create the mental image necessary to put you at whatever venue you wish.
