It is more present on some songs than others. With the SR60i, I can hear flaws in different recordings. Some songs are just way more sibilant than others. But, for instance on Dragonforce's new album, sibilance is fine on SR60i. But with the Magnum V4's... it is incredibly sharp. Every "s" consonant is just glaringly loud and it just makes me want to stop listening.
My current source / amp is NFB 15.1. I'll try more things tomorrow. I'll try different songs straight out of my iPod & Macbook Air as well.
I already contacted Rhydon about it. We'll see what he thinks.
Edit: Earcups are Honduran Mahogany. I bought them from Turbulent Labs.
