The only planar magnetic headphone I've tried with the Essence III is the Audeze LCD-X. It sounded great, but it's an easier to drive headphone than the LCD-4, so probably not all that helpful of a reference. I looked at the specs for the LCD-4 and Susvara, and it looks to me like the Susvara is way more demanding than the LCD-4. The Susvara has 14db lower sensitivity. So I think the Essence III will have enough power for the LCD-4, but not enough for the Susvara. For higher-end headphones, I don't think the power output will be the ultimate limiting factor. I still use the Essence III every day, but I bought a SPL Phonitor X to use as headphone amplifier & pre-amp for my speakers. With the HD 800 the Essence III amplifier sounds congested and dynamically compressed compared to the Phonitor X. So if you're interested in the Susvara, getting a separate headphone amplifier might be a good idea. It wouldn't just give you the power to drive the headphones, but you'd also get the most out of the Essence III since the amplifiers on the dac don't show you everything the dac is capable of.
@TheManko, to be honest I didn't own HD800 when I was writing it. BUT I was about to pick it up (right now I actually own it) and I was on a demostration like 3 years ago. Your impressions in this thread and when I listened to it made me pull the trigger to finally buy it. Thank you for that!! BTW, I'm also from Sweden. So possibly we bought it at the same place? "Reference Audio" in Stockholm. As far as I know the only store that activly promoted this specific setup. And I'm their "stamkund" since I been their more or less active customer for about 10 years. Last month I bought a Naim Mu-So QB to my GF for her kitchen for instance.
I got the HD800 and Essence III connected to my media server now. It runs PLEX and Roon with decent hardware and 1x4 TB + 4x10 TB NAS Drives from Western Digital. It's packed with with mainly FLAC and MKV files. I got a Van den Hul Optocoupler Mk2 toslink cable. I use Foobar2000 with WASAPI. I noticed the sound gets a lot better (about any track/genre) using a Foobar2000 preset called "Punch & Sparkle".
I think it's this one:

(I found it somewhere else on Google)
Except using it as a media server I use it as a workstation when I'm working websites. I noticed I don't want to have it in front of the computer while I working. Since I'm so focused on the process I do not fully enjoy the music. I rather like to have a "listening corner" so I plan to get the Rega Aria RIAA with a Rega P3 or P6. I also think this setup (and using E3 as a power amp for HD800) could be a "step up" sound-wise. Both because I acutally pay a lot more and also because I really (personally) love the vinyl sound. I THINK the warm vinyl sound might be a good fit for HD800 and it's detailed/clinical sound.
Since it takes time for me getting those thing, I will update this thread later in maybe 3-4 years or so lol.
However, I also plan to get a Mini XLR cable instead of the Stock cable.
I might order this one in a few months or so if I not going for Aria first:

I am not the kind of a "cable dude" that believes in differences in nice cables. I had a lot of cables both expensive one in more expensive setups and really cheap ones. I never experience any difference at all. However I'm a furnishing dude and I'm a gadget snob. So I like anything that is expensive (and where I getting a value for it) so exlusive details, long lasting built quality, a the "wonderfull feeling" is what I like to pay for nomatter if it's much money. But in this case maybe I believe there is a sounding difference.
Have I understood it correctly? Do the different outputs (Mini XLR) using different op-amps than the ordinary tele output? So I will just be able to enjoy MUSE op-amps if I will be using the Mini XLR output? Or am out with my bicycle now? (Swedish expression!)
