John, I get what your saying. But, if you have sold as many as you say, don't you find it strange that the fit issues only occured in this tiny cross section of the world? The outliers all ended up on one thread on Head-Fi.The "many" doesn't represent the majority. I have stated that several times, there will be outliers. If it was the case that they didnt fit the majority, I'm sure there would be many videos on YouTube or even comments being made on YouTube stateing as such.
The Rex5 sound great and I would say if there is any outlier group, it would be the people that don't agree that the sound is great.
