Sadly I did let my HD660S go once the S2 order was secured and wish I could in all honestly tell you but auditory memory is fallible.... definitly more bass, but I can say in all honesty that I never did enjoy the 660S as thoroughly as the new S2, so that might say something.Is it more like the older ones with layering or more like the S2. I suspect the latter and I’d be interested to know how much difference there is between the S1 and S2 in this regard, if any.
And unless you find there is absolutely something missing from the your HD660S and NDH30s you should be good...that is, until the next itch. : )
