CD quality ... are you joking?
Sure! You can not expect anything from aged, or poor aligned tuner which is fed few feet of bare copper wire as an antenna. It can not decode the stereo from received garbage signal. Sometime tuner has no capability from its manufacturer or already lost in due course of time. In city multipath signal kills stereo imaging and replaces it with HF noise.
For proper reception along with good tuner, you need good antenna and matching wire connection also. Its not that straight forward and easy.
Have anybody ever heard tuner with FM YAGI antenna which puts 1000-1200V (~0.1mV) signal into tuner ?
