New Head-Fier
Pros: almost perfect all-rounder, very realistic and wide sound stage, impressively detailed and very live-like sound presentation, extremely comfy
Cons: ocassional sibilance, for some electronica it lacks just a bit more subbass energy
I would like to share my experience with Sennheiser HD700 and compare them directly with AKG K701.
I bought HD700 as upgrade to my K701.

At first please note that I wrote these impressions immediately after I finished the listening of mentioned track/album.
 
Secondly please note that I'm comparing two headphones where one today costs two times more!
 
My equipment:
HTPC-> Foobar2000 with ASIO plugin-> FLACs -> moded Audiotrak Prodigy 7.1 Hi-Fi
(I know that it is the weakest point of my audio chain, but still quite capable to sound good) -> 
-> CustomWorks Hypa300SE (top class solid state DIY headphone amp)
 
My music range is quite wide - metal, rock, neurofunk, elctronica, industrial, minimal, classical/piano, indie etc.
 
Sennheiser HD700 (I paid 430EUR for new) vs AKG K701 (Price in year 2016 - 200EUR for new)
======================================================================
 
Metallica - Load (album)
Whole album seems to be mastered with preferred mid bass and more recessed trebles, which make these songs absolutely beautiful through HD700.Following of the bass guitar, which is perfectly separated, is simply a joy.Drum kick reproduction is nearly perfect but some sub bass energy below 50Hz is just slightly missing. But PRAT is very strong.Texture of distorted guitars is excellent. It is the main reason why I think that HD700 is a secret treasure headphone for metal, see below.Vocal is well placed just right in the middle horizontally and vertically- slightly distant. I noticed no harshness or shhh through the whole album, mainly due to mentioned mastering preferences.I have to say that K701 did not failed on this album and reproduced it very well. 
 
Metallica - ...and Justice for All (album)
What a suprise! After my experience with K701 I expected something lifeless and unlistenable. But HD700 brings new life to this album. At first impressed me the amazing texture of distorted guitar and outstanding dynamics of midrange! Second impression was the clarity of cymbals - impressive body and steel feeling to them. And finally I can feel and follow bass - very well defined and fast. PRAT was also very strong. Dynamics of drum is first class even on this old album.I would like to pinpoint the song "One". For long time it was the only song on this album which I was able to listen through K701 - mostly due to presence of acoustic guitars and it's perfect rendering b K701. Always I was enjoying the first half (mostly acoustic part) of this song with K701 due to wide soundstage and detailed midrange repoduction of guitars. When distorted guitars staredt to play I immediately stopped reproduction every time in the past. HD700 gave me even better quality in the fist acoustic part and gave me excstasy when distorted guitars starts!Amazing experience to me.K701 had no chance to compete on this album without bass impact, more treble extension and too much forward midrange. Also with K701 I found that the midrange is sounding something like unreal on this album. Also too much wide and horizontally stretched soundstage of K701 did not help to reach reality of sound.All in all HD700 pretty amazed me on this album.
 
Metallica - Black album (album)
I never heard better bass guitar reproduction than here on this album through the HD700 - on "Enter Sandman" I was easily able to follow it through whole song. Lead guitars are extremely alive and perfectly placed on soundstage. Drum kick has energy but maybe just a bit of lowest subbass is missing here to really feel it right.Cymbals are very clear, steely, crisp and have trully live-like feeling. Hitting of cymbals is extremely dynamic. It balanced between revealing and sibilant through the whole album but luckily to me it never falls to the sibilant side. But I can imagine that sensitive persons would like to attenuate a trebles a little on this album.All in all the repoduction of this album was outstanding and very dynamic to my ears...K701 was suprisingly not so far away in sound quality. Of course bass had less weight, but midrange quality was very good on this album. Biggest surprise were the cymbals. K701 had same livelike feeling to them but slightly less prominent. Good steely splashing was also there but to my ears the lack of crispiness and treble dynamic leaves the K701's trebles just a level behind the HD700. Also something was not right with soundstage. What is it to me I will explain later...    
 
Fear Factory - Genexus (album)
My main intention with this album was to check the speed of bass. Double kick reproduction is pretty fast with the right "sticky" sound with good amount of weight - not slow or lean at all! Lead guitar has again very seductive and organic texture which drag me to listen the whole album again with HD700.Trebles are naturally recessed/compressed and sacrificed for the rest frequencies on this master.HD700 tried to bring some life to them with their slight treble emphasis - no complaints here but also no amazement.K701 has bass which is same way fast but it lacks again the impact and weight. Also guitar is reproduced worst but more prominent. 
 
Black Sabbath - 13 (album)
Studio master is made toward the midbass and midrange, trebles and lower bass are less prominent in the mix. Also a lot of compression was used.
Somewhere I read that some fans were not happy with mastering of drums on this album. I have to say that I agree with them.
For the most time on album the drums are sounding thin to me, especially the snare. HD700 gave a some more body to them compared to K701 but simply you can not squeeze out of song something what is not there. Maybe HD650 can help here I don't know yet :) On the other hand the Geezer's bass is incredibly detailed and it is crushing my ears with perfect dynamic. But HD700 shines especially in reproducing of Iommi's guitar - organic and liquid texture with impressive placement on soundstage. The each detail is so beautifully reporduced that I have feeling that he is standing right here in front of me. Again I have to say that the midrange quality of HD700 is top class to my ears and this album proved it to me again.K701 lacks especially in midrange quality - there was simply something not right.I read that some people described it like plasticky sound and now I know what they ment. There is much more midrange quantity than quality from K701.
Here I would like to pinpoint song "Zeitgeist". K701 was able to reproduce this acoustic trip to the outer space very good so I had big expectations from HD700. And HD700 outclassed K701 again in every spectre especially in realism and detail of reproduction. Especially the percussions were more crisp and alive with HD700.Also in "Damaged Soul" I felt like I'm sitting in front of the band inside the club and they are jamming only for me. Beautiful experience of precise soundstage imaging of HD700. K 701 had no chance on this album based on my ears.
 
Rammstein - Reise, Reise (album)
First time with HD700 I experienced shhh/sibilance issue during intensive vocal sequences. Not nice! On the other hand the midrange shines again. I would say that I don't agree that mids are recessed on HD700. I just think that mids are too much prominent on K701. It is same logic when my friend told me "I think that Note 4 is too big smartphone" and I told him back that "I think that other smartphones are too small":) . On HD700 the quantity of mids is just right to my ears. Also the quality of midrange on HD700 is excellent. I would like to mention it again - quality (HD700) vs quantity (K701).
 
Black Sun Empire - Salvador (song)
Simple overall impression - with HD700 I can finally listen to the neurofunk, but with some small compromises.Bass on this track is prominent in the mix as it is expected from neurofunk. With HD700 the bass has a very good quality but slight lack of the subbass is more audible here than on metal tracks. HD700 is trying to heal it with more energy on midbass but body is still slightly missing. I expected a bit more here I have to say. But compared to the K701 it is like the night and the day to my ears. K701 was not even close to the overall bass quality/quantity. The rest of spectrum was reproduced very similar, but for neurofunk the bass is essential. It looks like I have to buy the HD650 especially for neurofunk...hmmm
 
Black Sun Empire - Tripel (song)
More-less the same as for "Salvador" is valid also here but on this track I was more satisfied with bass quantity of HD700...

Combichrist - We Love You (album)
Texture of synths are excellent, also midbass. Again I beg for just a bit more subbass here to get a perfect bass. But a little worst thing happened - on some tracks I experienced some strong shhhh in vocals so I had to go down with volume. What a shame! The overall reproduction was perfect through the whole spectrum until sibilance appeared. But overall full bodied sound through the all tracks can outshine this issue. But, you know, we always want to have everthing perfect.. K701 had no chance again with modern industrial where the strong bass needs to be reproducted.
 
Limp Bizkit - Chocolate Starfish and The Hot Dog Flavoured Water (album)
Great energy of this band is rendered very well on HD700. Drummer plays a lot with cymbals and HD700 really likes it a lot (and me too as well). The drums on this album are one of the best sounding metal drums which I heard so far (yes, sometimes too much compressed, but what we can do...). Kick is fat and strong, PRAT is great. Distorted guitar shines again. Especially in "Full Nelson" the render of distortion guitar is spectacular. Very enjoying experience overall! K701 shows the ability to similar quality of reproduction, but lack in bass region dismiss it. The trebles were very good and close to performance of HD700. K701 struggled in midrange again where the naturality of instruments (especially guitar) was lacking. But again treble of K701 was very good here!
 
London Grammar - Wasting My Young Years (song)
This nice indie-pop I played especially to test the rendering of female vocals. Out from all tested tracks, on this song the both headphones were closest in terms of performance.
K701 is very strong in female vocals reproduction. The voice was rendered perfectly and just right to my ears. But HD700 did it the same way and add on top the more coherent soundstage.
 
Depeche Mode - Welcome To My World (song)
Fat analog synths needs good bass extension and proper imaging. During this track I realised what is really wrong with K701 to my ears - IMO the Headfonia was right in their review od DT880/HD650/K701 when they tried to describe the K701's issue with soundstage. To desribe this I will use terminus-technicus from recording studio - the PAN.PAN is simply the potentiometer for setting where the recorded sound should play - on the left side(let's say that maximum is L10), on the right side (let's say that maximum is R10) or in the centre of soundstage (let's say value is 0). K701's soundstage is rendering well sounds around the centre (usually drums, bass guitar, vocals, etc.). But when I start to focus on soundstage quality between PAN=0 and PAN=L5 or R5 I found...virtually nothing! There is hollow place on soundstage which is filled only by some "air" or by stretched sound bodies from more left/right soundstage regions but not with the real body of instruments. I think that this is caused by lack of bass which is making drums and bass guitar sounding too thin and somehow separated from the left/right side of soundstage spectrum. This defect generates the hole between left/right and the centre of soundstage. Also I found that sounds which are playing very close to the maximum PAN=L10/R10 are compressed and squeezed toward the end of soundstage and there is no air around them. Something like a border is present here below the maximum PAN.
HD700 has not any soundstage issue at all. It is as wide as K701 but there is still air around the instruments if they are playing on the corners of soundstage. The soundstage of hd700 seems to me like a limitless place without any borders, which push HD700 to much higher quality league than K701 in terms of soundstage realism and imaging.
 
Ludovico Einaudi - In a Time Lapse (album)
I expected though fight here in classical/piano music arena. K701 use to render piano very well, but compared to HD700 reproduction was somehow lifeless and not 100% natural. HD700 shows how to do it right. Especially on "Brother" the gradation was ecstasic. HD700 wins due to precise midbass and it's fluent connection with midrange. Midbass gave a perfect dynamic and body to the piano while the midrange rendered main tones more realistic than K701. In the end the real sound stage and top class layering of HD700 nailed K701 definitelly.The song "Orbits" made this "hole" between these two headphones even more evident. The HD700's trebles plays their best in this track - the sparkling bells/tringels with prominent violin made me cry. Sorry guys I shall not to write it :) Ehm...again I have to mention one of the biggest weapon of HD700 - the soundstage realism and layering ability.I think that K701 is very good in this aspects (especially layering) but HD700 clearly plays higher league."Newton's Cradle" with HD700 was experience out of this world to me. The soundstage and imaging was so real that I thought I'm right in concert hall. Reproduction had everything which it should have IMO. Trully spectacular here. In overall the HD700 gave me absoultely flawless experience with piano/classical music, much better and unforgettable than with K701! Extremely real and strong experience to me...
 
Andy Stott - Hatch The Plan (song)
...good elctronic track to test sibilance:) HD700 impressed here with much better bass than I expected. Electronic kick drum is going quite low and I have no necessity for more subbass here.  Noisy sounds and vocal effects are usually a good feed for HD700 but on this track they are very close to sibilance...a there it is , the first shhh...and second shhh! Hmmm, I'm not happy. I have to say that one should be careful if  knows that some particular track is mastered with dominant trebles and agile/loud vocals, HD700 can have problems (more correct is to say that your ears on high volume can have problem:) On the other hand also K701 was sibilant on this track but much less. The drum kick rendered by K701 was, gently said, simply unsufficient here.
 
Pink Floyd - High Hopes (song)
Not much to say - true joy with HD700. Very coherent and alive, perfect details and soundstage. K701 is able to sound close to it but midrange and bass is playing lower league evidently.
 
Pink Floyd - Coming Back To Life (song)
Very complex song, because guitar on left is often playing different notes like guitar on the right. With K701 the soundstage issue mentioned above was clearly audible - the song sounds strange and not coherent at all - like two different songs played at the same time from left to right perspective of soundstage with common drums. HD700 had again no issue and due to perfect sound stage consistency the song was rendered really like the one song...Idiotic describe I know :) 
 
OVERALL
=======
HD700 is clearly the upgrade to K701 to my ears. It is perfect all-rounder. It can play very well a lot of different genres. Even old metal and rock tracks are sounding very good again through them. Ocassional sibilance can occur if the song is mastered with lot of treble and lot of shhh in vocals. On the other hand K701 is not sibilant but due to forward mids they were even more fatiguing to me for long time listening at higher volumes. HD700 was never fatigue to me at all on. HD700 simply improves the every sound aspect of K701. Bass is better, midrange is better, treble is better, soundstage is better and comfort is better as well.
 
Also the design is very nice and the comfort is excellent.
 
All-in-all HD700 is a very good headphone in my opinion and the right upgrade for me.
Also the HD700 price dropped a lot during last months. Current price tag of 430EUR is just OK in my opinion.
 
PS: Currently I'm finishing DIY clone of MAD Ear+ HD Super II tube amp so I'm looking forward to the happy marriage with HD700 :)
 
Thanks for reading my mess...

Thanks all for reading! Yes, black album is mastered almost perfectly IMO. But as I wrote, I was really impressed how good HD700 sounds when playing metal. They have some special ability to make older tracks (especially tracks from 1980 to 1990) sounded very good and same time reveal all micro details on recording. K701 is just like opposite kind of animal - they really hate to play my metal/rock oldies collection...
 
Today I listened to the Tool - Stinkfist,  and Vicarious. Both sounded amazing with HD700 to my ears, especially the overall realism and sound of guitar.
 
I will update my impressions here when I will finish building of DIY clone of MAD Ear+ Super HD II tube amp...
 
PS: Anyway I think that new AKG K701 for today's 200EUR is pretty damn good buy!

The difference though is the new k701s are from China, where the originals were from Austria. Maybe the quality is the same? I like the k701s for soundtracks and classical. But yes, I could see how you love your new headphones, seems like they have pace for your favorite songs and a sound that makes some of the older and maybe duller metal dynamic! Enjoy! Every once in a while I do find the k701s wake up. Today was Duran Duran and maybe due to the vocals, they worked? I have two pairs, lol

LOL you seems to be addicted to K701 same way as I was :)
 
Yes, the "Made in Austria" label on cups is missing on current K701 production. Also you can see on images i.e. at AKG homepage that there are no bumps on headband anymore. It is good news for a lot of people I think, including me.
 
Regarding quality I think/hope that acoustically they should be 99% same as older production from Austria. I assume that AKG have set very high quality standards for their products and they will not risk their credit by using of cheap materials or assembly quality, even if product is produced in China.
 
As I told - I think that at 200EUR price tag one will not be able to find today a better headphones than AKG K701 - in terms of transparency, layering, detail and sound stage. The best bang for buck especially for piano/orchestra and vocals IMO.
 
Mine K701 are 6 years old and they were made in Austria. I had a plan to sold them but today I decided to keep them. :)
 
Keep it play!

New Head-Fier
Pros: very good sound due to Wolfson DAC and good circuit around, neutral/slightly warm sound signature, replacable OPAMPS, 7.1ch is handy
Cons: bad quality of Win7,8 drivers, low voltage on analog outputs, not able to drive power hungry headphones (such as AKG K701)
I'm using this sound card for 5 years. It replaced that time my previous card M-Audio Audiophile 2496. As far as I know at present (2014/2015) it is not possible to buy this card as new in Europe. Today ESI Audio is offering Prodigy X-Fi NRG in similar price range which is completely different card (AKM DACs, Creative DSP chip etc.). On actual Audiotrak webpage I found AudioTrak Prodigy 7.1 LTM which would be currently available for 70$. It is based on same VIA Envy24 chip and equipped with similar Wolfson 8770 8channel DAC as old Prodigy HiFi. LTM uses SMD Opamps so easy tweaking is not possible...
 
Stock Audiotrak (formerly ESI Audio) Prodigy 7.1 Hi-Fi had very good sound signature for price around 100$. Wolfson 8776 DAC is producing detailed sound with slightly warm signature which is typical I think for all Wolfson's DACs. I had no chance to compare this card head-to-head with my previous M-Audio Audiophile but as far as I remember Prodigy offered at least the same level of sound quality on analog outputs. Ability of driving headphones on Prodigy was significantly better than on M-Audio Audiophile in terms of details and overall volume as well. Please note that Audiophile has no headphone output so I connected headphones to the analog outs. I had no problems to feed my good old 32-ohm Sennheiser HD 212 Pro with Prodigy. But when I switched to AKG K701 the lack of power and resultion on bass was noticable. So I decided to try different OPAMPS...
 
After several setups (OPA2111,OPA2227,LME49720...) I ended with 2xLME49710  with Browndog adapters on both headphone and analog outputs. Sound was less warm, more crisp and even more detailed. Same time there was less bass attack present with K701 but significantly better bass resolution and instrument separation. Also soundstage was improved to my ears.
 
It would be nice if drivers were in the same league as sound. Unfortunatelly they were not. Under Windows XP it was fine, when I moved to Win 7 some bluescreens occured during playback in Foobar and there was no sound at all when I woke up PC from sleeping mode. Also when I moved with Windows volume slider the sound stopped and restart of PC was necessary to bring sound back...
Currently I'm using Win 8.1, I tried latest driver's version but it was horrible at first - no sound at all and lot of bluescreens. I switched back to old 1.08 version and it worked but annoying cracking to sound sometimes appeared. I tried to configure card, change buffer size, reinstalling but without success. Then I reinstall Win8.1, disabled on-board Realtek codec sound and installed back latest drivers for Win8 - no bluescreens, everything was fine same way as with 1.08 drivers but annoying crackling remained. Then I tried something different and found solution...
 
I have Prodigy installed in PC with i3 4330 and ASUS mainboard. In ASUS PCSuite software there was Auto performance mode set up which kept CPU strongly underclocked (approx. 700MHz). Prodigy is using really old VIA chipset which is very CPU power hungry during playback. When I realized this I set High performance profile in ASUS Suite and cracking was gone! In case that you have similar sound crackling experience with relatively old sound card try this! 
 
All in all crackling was not a driver issue but my idiocy was a problem. But as I wrote before life with ESI drivers was such a fight on Win7,8 anyway...  
 
Prodigy 7.1 is also suitable for gaming. You can not expect SoundBlaster's boom-boom effects but I was satisfied with sound in games and movies too.
 
In summary this card was very nice purchase that time. If you are able to find this card new or used, you need 7.1, your budget is low and you are using Win XP  - this is very good buy! Using with Win7-8 is not without problems...If you are not tweaker maybe you can try very similar Prodigy 7.1 LTM which is currently available for 70 bucks...
