Hmm first I will say the HARX700 and HARX900s are easily out classed by the newer JVC offerings the HA-S500 and HA-S400
I would rate them like so. Just my opinion of course.
HA-S500 using ATH- pleather pads.
HA-S400 using AKG pads
HA-S700. The worst sounding JVC product guaranteed!
About what I thought you would type. Thank you! Great list! Well, I might be selling a bunch of stuff again. Impressions went in for the the 1964 EARS V6 (suppose to be tuned exquisitely for the audiophile's ears. If I end of loving it (as I believe I will knowing how much I love the Quad), I can see a lot of things going except for the W4, FXD80/70, ASG-1.2 and S500. Of course, I'm keeping the Quad too.
Finally, long overdo, but expect a detailed review of Audiofly four headphones this weekend (Monday at the latest). I can't begin to even express how busy I've been.
