[Preface: first post at headfi.org]
Just purchased HD 700. Just one word:
Wow!
Soundstage is quite good; listening to CDs playing in a roughly 10-year old, Sony surround sound AV system, I'm hearing excellent tonality and very good separation between instruments. If there are issues or problems with certain higher frequencies, I'm not able to hear it. This could well be me or my ears; I'm no longer young.
Comparing the actual listening experience to some of the earlier reviews of the HD 700s, it's just my gut feel but Sennheiser may have made some changes to these headphones since initial release. Over the past year or so, I've read many forum posts and reviews. Looking back, some of the latest reviews here -- including in this set of HD 700 Appreciation posts -- and elsewhere helped me a great deal with my choice.
I debated quite a bit about the purchase of the HD 650 in lieu of the HD 700. But the latest price drop by Sennheiser was too good to pass up.
I'll be very interested to see what, if anything, Sennheiser releases to replace the HD 700.
I'm looking for recommendations on source gear, including a DAC and amp; but, from my earlier reading at head-fi, I think I need to search elsewhere (although if you want to throw out some ideas, that would be great).
Thanks to all who posted before me; without some of the encouraging words found here, I might have picked differently.
The HD 700 is a winner.
ps I'm moving up from a Sennheiser HD 280 (which I use at work a fair bit) so, for me, this is quite a change.
