1) How large are the earcups? My AKG K240s are large enough, but the Sennheiser Momentums are too small for me.
2) Do they benefit from an amp? They're 32 ohms, and I've heard that they don't require one, but would a fiio e17 be a significant improvement? (for the amp or DAC) I'm currently playing directly out of my Asus N56 laptop or my iPhone 4S.
3) Toronto: does it have a hi-fi store where I might be able to try on the PSBs?
