Haha, I can relate to this. I started with the SR225i, then went to the SR325is. Then I tried the SR60i with L-Cush pads just to see if I could in good conscience recommend it to my friends as a nice low-cost headphone. Well, much to my surprise, I actually ended up liking the sound of the SR60i better than the SR225i and the SR325i!
So it was an interesting way to learn that more expensive does not always mean more enjoyable. Especially in this headphone game.
