Since this is my first post I'd thought I put it up here. I've been looking for my first "real" pair of headphones lately (mostly just been bumming around on these) and I was thinking about the Grado SR225i. I've only ever tried 1 pair of good headphones with a good amp (Schiit Valhalla) in my life, the old Grado RS2, and I really liked it and since I auditioned the SR225i, I really like those too. I wanted to ask a few things.
1: I was thinking about getting the E17 amp and I was just wonder if I would need any other additional cables (minus the 1/4 inch to 1/8 inch adapter for the SR225i).
2: Since I (obviously) like the RS2 better, is there any other sub-300$ (Canadian) headphone that would sound more similar?
3: Will the amp make that much of difference?
Thank you in advance for answering my nooby and probably bordering on facepalm level questions.
