Sorry, dude.
I do not know what JPN thingy is.
It's cool you are using the AT amplifier. It makes sense since I assume they are voiced together.
If Naim made a headfones, I'd use it, too.
I don't blame you for not liking the Grado as they are not for everyone. I still prefer the feel of open cans, tho.
But sounds like I could live with the W5000 since Headline2 is working pretty good with the W2002.
AKG271 might be less costlier than a W2002, but it's not a bad 'fones for the money. Interesting thing is that most of the closed cans around the cost of 271 or less just do not have the clarity of RS1 or W2002. Guess this is where you pay your money.
I am not having ANY bass problems with the W2002 this time with the Headline2.
Its bass delivery is different from the Grado but it's well articulated with slight bloom I don't mind at all. Your comments on the W5000 regarding the lack of impact is worrisome, however.
Where I see it, if it's faster, then it should not lack the initial transients at all.
Would you say the W5000's presentation is similar to the k1k?
Thanks again for your comments.
Any other closed cans reco. also would be appreciated.
