@ghdprentice It's never happened to me either in my personal system, and for the exact reasons you mentioned, proper research and auditioning.
@blisshifi I have to say the Scansonic MB2.5s showed me what could be done with a sealed ribbon tweeter, better sound than the Esotar II I had liked in the Dynaudio Sapphires.
Occasionally I have been wowed by the sound of great budget system and its probably a combination of things that all went right. Rare.
