No problem ! Can ' t wait for Episode 9 , this show is seriously something special . <| sep |> I have MSR 7 are they are super comfortable to me and my head shape , but that ' s all subjective . If they were to be uncomfortable to you , you can leave them stretched over your PC case over night , that should do it . And an amp is not needed , I do have it just because it gives you more freedom and makes the sound breathe at higher volumes which I really like . Only if you were using them with the on board audio , you ' d probably have shitty sound as I did . I ended upgetting the Fiio e 10 K DACAmp and it works like a charm . <| sep |> hard to say . I think theoretically the impedance presented to the amp does change by a small amount . Been experimenting with different cables , from thin gauge RatShack to Audioquest woowoo to this frankensetup . None of it detracts from the whatever music is on the deck
