Safe to assume rough = unpleasant, mayhaps grating, uneven, or perhaps obviously unnatural in some fashion? Well i have not experienced this with my Fazor Lcd-2. The original Fazor which i had before really had elevated treble in my opinion but even then i did not think it was rough, but rather a bit unbalanced. To each their own, you obviously do not like the lcd series, and i believe on that we can agree. Its as simple as that.
