I can so with some serious conviction that you wouldn't want to bother with the DJ100 without the amp. It's just astonishing how different a headphone they are with and without the amp. You just don't see this kind of thing very often.
I dont know how i feel about the Koss Dj100, i like Koss, only disappoint Ive had with them is my QZ99 and because i didnt read the reviews...they do isolate tho.
i dont like to carry around an Amp, i have one in my desktop, but then why would i use portable cans in my desktop? for that i have others.
I liked the description in the review but i dont want to use a portable amp, but then I'll be missing a lot of their potential, so i guess they are not for me. great review.
Lots of comparisons with the HP700 huh? i guess is coming soon.
