Slappy, a good system is the one you spent your hard-earned money on and decided after weighing the options that you wanted to buy. How's that for a deflection.
I will contend that a good system will not sound good in a bad room. It is possible for a system to sound good in an untreated room just like it is possible for you to get the best parking space at Goodwill the next time you a re shopping for new gear : ). It is just a coincidence that a system sometimes works in a room without any treatment, but the majority of systems, mine included need help with the room.
Why handicap a system capable of excellent sound? Put it in the best environment you can justify!
