I don't have the SR60i, but my very first Grado was the SR80i. Unlike you, I instantly liked the sound. The Grado is my third my headphone, after the Audio-Technica A700 (thumping bass) and the AD1000 (zero bass). My jaw literally dropped to the floor....I couldn't believe how "right" the Grado sounded. For $138 AUD, the Grado blows the other two more expensive headphones right out of the water. The sound was full, wholesome, rich, sweet, liquid, warm, detailed....I'm out of words

Perhaps your ears were more used to listening to quality headphones; mine had been relegated to either apple's earbuds or bose's

My first pair of high quality headphones were SR60s(I am now using the SR80s which I find very slightly better for soundstage and base) It is possible you didn't notice it first because Grado phones can be sort of particular about the type of music you use them for and you need a nice quiet place(imho) because of zero sound isolation. I will have to check out Sikth, thanks for that tip!

Yeah I should of mentioned that I bought them because I read about how great they are with rock, I listen mainly to metal music so they seemed like a great fit. No prob with the Sikth recc, really an amazing band if you can handle your metal/rock with weirdness (they have 2 singers who sing in really weird ways, its strange at first but really unique)

I'm sorry, I had to join to just say, **** YES KVELERTAK. That is all.
