Hello, I just saw that Sennheiser unveiled the new HD700s at CES, suppose to fill the gap between the 650s and 800s. They look like a toned down version of the 800s, better looking IMHO. MSRP $999, 150 ohms impedance. I wonder if the cable connectors will be the same? Anyone else has any info or has heard them please let us know.
Cheers,
Shawn P.

just very quickly for those who read german: http://www.sennheiser.de/sennheiser/home_de.nsf/root/press_releases_100112
the specs are at the end of the press release.

Jude did a write up of them on HeadFi: https://www.head-fi.org/t/589738/sennheiser-hd-700-official-unveiling-tomorrow-at-ces-2012
The initial impressions look to be favorable.
-
Thanks for the links gents! Well Jude seems pretty impressed.. Being the card carrying Sennheiser fanboy that I am I guess I'll have to find someone in town that will be carrying them and give 'em a good listen.
Cheers,

Seems like from what I've been reading they need some tubes to warm them up a little......I was hoping they would have a more 600/650 sound than 800.
-
Personally, I found the 650s a little dark when I got em. I bought a cable from Zynsonix, thanks to our fellow Bottlehead HF9, replaced the foam over the drivers with some material from ladies nylons, and of course tubes. Love the way they sound now.

I replaced my foam on my HDs with grill cloth. Opened them up just enough. Perfect match with the Crack and Moon-Audio cable.u

I used nylon stockings and the top end opened up.

That may open up more than the top end..........

Ha, maybe a little too bright, but Senn. sales would increase exponentially. Would have to buy some stock!

IF anyone buys a pair, PLEASE let us know ALL about it.....

I'll start here even though this thread has been inactive for a while:)
New on this forum and expecting a Crack at my house in the next month or so! Just wondering if anyone has any experience running the HD700's with the Crack or any other Bottlehead Amps?
I love the Sennheiser sound signature and I'm enjoying these phones without an Amp right now (unfortunately) so I can only image what they will be like with a great amp!
Also running a Modi Multi Bit DAC and an AudioPhellio 2 if that makes any difference to answering the question.
Thanks!

I don't have any experience with the HD700's. But I feel its worth noting that the Crack OTL might not be the best match. Crack and Crackatwoa work best with headphones that are 200 ohms and higher. Unlike the HD650 and HD800 phones at 300 ohm the HD700's are only 150 ohm. Bottlehead's Mainline amp is better suited for lower impedance phones. The now retired S.E.X. amp would have been another good choice. There is talk of a replacement in the works but that might take some time to be released.
-
Thanks for the reply. I wish I could afford the Mainline! That would be my first choice. I didn't see the S.E.X. available on the website, am I crazy or missing it?
I also thought about the impedance situation as you mentioned, but since the crack was so affordable and it said headphones higher than 120 ohms, I went with it.
From what I've read online, it's the best bang for your buck tube amp wise. I did read on some other forums about some guys who have paired the 2 and love it, but I figured I'd ask here too.
Thanks for your answer and the info!

No, you aren't crazy. The S.E.X. amp was retired in May of this year.

There is no doubt that the Crack amp is the best bang for the buck out there. I bought one of the first ones and have enjoyed listening to it in my home office for several years now with my beloved HD600's. The stock build is fantastic but the Speedball takes it to the next level. You really should consider that before any other upgrades.
Keep us updated on your build and how you like the sound. Something tells me you will have a big grin on your face. ;D

I have the HD700s too and decided to order the crack after reading CNET's Steve Guttenberg recommending the crack-HD700 combo ("my budget-priced Bottlehead Crack headphone amp sounds astonishingly good with my 300-ohm Sennheiser HD 580, and 150-ohm HD 700 headphones", google that quote for the whole article), in an article about headphone impedance no less.
Will do a listening comparison with my AMB M^3 (which theoretically is excellent at transients with its OPA627s opamps, and has tight/precise bass), but only after I solder the must-have speedball in. I suspect the mechanical damping is so good on these cans that it won't matter much.
-
A little searching found this plot of impedances for several headphones:
https://www.head-fi.org/t/623554/sennheiser-impedance-marketing-question
Notice that the HD700 has a huge impedance peak of nearly 400 ohms. With Crack, that will give a boost to frequencies around 100Hz, probably around 5dB. The other phones on the plot have a much flatter impedance plot, so even though they are 50 ohms or less, they will show less response fluctuations with Crack.
These impedance interactions are of course not the only audible differences, but they are the ones most easily analyzed. There is still no substitute for listening!
-
That won't necessarily be a bad thing with HD700s.
-
Thanks so much for the replies everyone. I am truly looking forward to building this amp and definitely will look into the speedball upgrade in the near future:) I want to get it built and spend some quality time with it before I go off upgrading and such. Definitely want to check out some other tubes as well:)
-
You're in for a treat my friend, the sound of this combo is unbelievable :)
With the HD700, more bass compared to my AMB M^3 (even with bass boost all the way open) and no harshness/sibilance issues.
Doc got me addicted to Crack!

Maybe no one is paying attention to this thread anymore but Massdrop has the HD700 on for $399 for a few more days.
