Absolutely disagree with this. Great highend equipment doesn't ruin a music collection. A great system will make some things sound better than others. But a great system does not beat one over the head with differences. Reducing distortion, time smear, ringing and other problems helps all recordings. Poorly built equipment and improperly matched components can exagerate the differences between recordings. This can happen because the system is so uneven that some recordings click in while others don't. Stax headphones are a great example. As revealing as it gets but few recordings sound truly bad on them.
