I was able to get a pair of brand new HD 650s off ebay for a good price (compared to everywhere else) so i couldnt help but to get them. I have a Macbook Pro and a lot of my music is from sources all over (not much was ripped from CDs or via itunes store) so the quality varies..
I was just wondering, if i just use the 3.5 adapter and plug into my headphone jack on my MBP, what am I missing? I have a pair of Sennheiser 448s too and, other than the obvious quality difference, the only thing i see different is i need the volume set higher for the 650s to get the same loudness. Ive read everywhere the 650s demand an amp to get the full quality but they seem to be sounding pretty good as of now.
So, i guess im asking, is there gonna be a comparable difference with an amp if my source has variable quality music?
Any input would be appreciated! Ive learned quite a bit since joining from you guys :)
