If good is taken as accurate then absolutely yes, of course it should sound bad
If good is taken as a nice sounding system with plenty of forgiveness, warmth and oodles of extra harmonic distortion in the bass and lower mid then NO.
A system that colors sound in a pleasing way can invariably make a bad recording sound passable. ( a good recording, however, will never shine as much )
Since the majority of recordings are mediocre or mastered for mediocre systems...selection of a system is a matter of opinion/choice and even a very accurate system has its limitations/drawbacks.
Many mastering engineers in studios with $100,000+ systems/facilities will still use something like Yamaha NS10's, just to see how their master will translate to a mediocre system. (the majority of systems can't properly handle the dynamics of lifelike music and lose balance)
Fortunately the odd one slips through....one where the mastering engineer has not been heavy handed with a soft limiter. Some genre's fair better than others.
