This is the excuse for all things head-fi and is meaningless to me. I'm ok with people explaining why they prefer or think something performs better. As long as I can understand why you come from where you come from, then viva la difference and all that.
That is a good point, and I understand why people would view it as an excuse. However, for me, I'd rather have an excuse for a certain claims instead of bickering about earphone x being better than earphone y for such reasons and then causing a commotion in a thread over it. (This is not implying that anyone here was arguing, but I've seen it at other threads like the discovery thread a few times.)
However, your post summed it up for me and I thank you.
It's unfortunate that the tenores have a QC issue, if it weren't for that, I'd purchase one. I'll see if I can figure out a way to contact zero audio @japan regarding this matter. Until then, happy listening headfiers.
