Audiofeil:
That was never the conclusion. The cantilever on that cartridge was sold to me bent, which I believe was causing a lot of problems. And since I bought it used, the stylus may also be worn (I never looked at it under a microscope).
As for the Denon, the alignment is spot on. I hear no signs of mistracking whatsoever, and inner groove distortion is nonexistent. So to answer your question, no that is not the issue here. I believe this has more to do with improper cartridge/tonearm matching. Or perhaps the DL-103 is inherently a slightly bright cartridge. I have a strong distaste for even slightly bright audio components, so that may be playing a part here as well.
