Hello to all.

Will the Kennerton Rögnir, Kennerton's premium closed-back planar headphones, become, one day, a Kennerton's iconic headphones?

In any case, the poster in the background of this picture of the Rögnir taken in the office of Kennerton's CEO, Valentin Kazanzhi, is already, for sure.

"We Can Do It!" is written on that poster.

So, did they do it? (the guys from Kennerton) to come out a really nice and really good top-of-the-line closed-back planar headphones?

I, for one, would say; Yes, you have done it!

Well done guys.

Great!! I waiting the review.

Thanks Eric.

How do people find the upper midrange/treble on the Rognir? I enjoy the tonal smoothness of the Thekk; but it would be nice to have a little more impact and richness, or "tonal density" as people used to say early on in this thread.

Hello Andrew.

We will know soon, because the first buyers of the Rögnir should soon receive their Rögnir headphone including our friend Dave (@ithilienrp).

I pretty much agree that it's very difficult to tell how a headphone will sound just by looking an FR curve, especially if it's not compared to a headphone you already know.

As already said, I think that the Rögnir will sound very good in the low frequencies (bass and sub-bass), without roll-off under 50 Hz (unlike the Thekk for the sub-bass), because the FR measurement curves allow to say, without too much ambiguity, unlike the high frequencies.

So how the Rögnir will sound in the high frequencies, well we don't know anything about it, except for this one notable comment made by Igor Boitsov who had the chance to listen to the Kennerton Rögnir (unfinished prototype) in the Kennerton offices.

Bog Oak – The Rarest Wood in the World​

ABOUT BOG OAK (Quoted from external source): "The bog oak is unique material and has no analogues (unique in time that can not be reproduced in the future because of the climate conditions at that time unique in time and environment)... Bog Oak timber has been preserved from decay because of the anaerobic + acidic conditions within the bog. Bog oak was preserved in the ground in a period roughly between 3000 to 7000 years ago. ... The bog lands of Kildare and the Bog of Allen are vast living treasure troves for this precious and most coveted material."
Most bog oak comes from the British Isles, Northern Europe or Russia. But the most famous deposits are the peat bogs of Ireland and the fens of East Anglia, in the southeast of England. While bog oak can form over as little as 1,000 years, it can also be almost unbelievably ancient. Specimens are regularly radiocarbon dated to between 2,000 and 5,000 BC. This means some trees were alive during the building of the Egyptian pyramids or Stonehenge, at the very dawn of human history!
The fact that Valentin is so modest estimating the age and rarity is a testament to his modest and honest personality I think

BOG OAK IS SO SOUGHT AFTER THAT PEOPLE MAKE JEWELRY FROM IT

The bog oak is unique material and has no analogues (no comparable descendants today/ environmental conditions will never be recreated due to time line global climate conditions). Its formation takes place over thousands of years, and the result is amazing. The bog oak is strength, hardness and nobility. In addition, it is more dense than normal oak (15-20%), which provides phenomenal durability. And it is beautiful, its natural pattern, like a fingerprint, is unique. The color of the bog oak is not only black, it varies from ashy and reddish-brown to mottled "leopard" options.
Using bog oak- the features include:
- unique characteristics of the wood; - the elegance and nobility; material, trees for which grew during the time: from the middle ages of Stonehenge to the era of the Egyptian pyramids.

THE WOOD KENNERTON CHOOSES IS NEVER USED WITHOUT REASON
MAKING EACH EKNNERTON SERIOUS COLLECTORS ITEMS BUILT WITH NO EXPENSE SPARED FOR PERFECTION

BURN IN ROOM FOR DAYS AND NIGHTS AS THEY SAY IN THE VIDEO

INSANE AMOUNT OF DEDICATION TO DETAIL- I WILL NEVER FORGET THE DAY I "DISCOVERED" KENNERTON BRAND AND I ORDERED THE MAGNI AND GH50 FOR THE FIRST TIME- IT WAS LIKE AN EXOTIC TREASURE THAT I JUST UNCOVERED- AND I STILL FEEL THIS WAY TODAY-FOR ME- KENNERTON IS ONE OF THE BEST HIDDEN SECRETS FEW KNOW ABUT BUT ONCE THEY DO THE ALLURE IS OBVIOUS AND I WOULD THINK CREATE A LIFETIME OF ENJOYMENT + PRIDE OF OWNERSHIP

Hi all.

There has been a lot of talk lately about the planar diaphragms of orthodynamics headphones (thicknesses and possible reinforcements), and a little less about the magnetic circuit used to make them work.

Well, it seems that the Russians have found something interesting and new concerning the magnetic circuits of isodynamic headphones, and Kennerton will not be far behind ...

So, at Kennerton, in the future, a new planar headphones equipped with a brand new type of ortho/isodynamic driver which would be called "non-meander Isodynamic Emitter"?

A bit off topic but does anyone have a graph of the LSA HP1? I want to see what's the Kennerton planar with less subass roll off, but cannot find that one
Thanks!

Unfortunately that's a bit of outdated info...originally a known modder in Russia goes by the name Snorry researched and patented the meanderless emitter and was supposed to collaborate with Kennerton in releasing a model under the Kennerton name. That partnership did not come to fruition and the companies parted ways. Snorry released his own headphones w/ his flagship model NM-1, which you can read up here if you want to know more about that technology.

OK. Thank you for the clarification ; it is true that the above info dated back to 1 year ago.

Yes.

Thank you very much Eric! Didn't expect the LSA to have less subbass roll off than the Thekk. Using the ECL should add a few dbs in that area tho.

Thanks for the detailed info as always Eric! I have the Vali 2019 and love the sound signature and the organic timbre that they have.

I own the Magni V3 and the Gjallahorn JM as well, so I know how good those graphene coated driver can sound, so Im really interested in how will they sound in an open back desing.

Anyways, looking forward to read some reviews.

Hi Tano.

I've been thinking about picking up either the Magni or Gjhallarhorn JM fairly soon and wondered if you had a preference for one or the other. I'm having trouble deciding and have read multiple reviews.

Hi! I really have no preference, it depends of my mood and the musical genres .

The Magni has amazing dynamics, impressive slam while maintining the clarity, Id recommend them if you are into modern genres, specially EDM or you are a basshead (althought they work great with everything).

The JMs also shares those abilites but they are technically superior and sound like an open back (they got less ressonance than the Magni) with bigger soundstage and better imaging. They can slam pretty hard as well but they aren't as powerful as the Magnis in that department.
They are also very versatile and Id take them over the Magni if you listen mostly to rock, jazz, folk, metal...

Whatever you decide, I think you won't be dissapointed.

The Thekks driven by the RSA Apache with the Sparkos Labs SS2590s with an Exogal Comet Plus sound awesome tonight

Appreciate your thoughts! I'm pretty much a prog rock and metalhead. Sounds like Gjhallarhorn is a better choice for me.

Hi All.

A big thank you for my compatriot Philippe (@Hartford) on the French forum who found me links (in Russian, but very easily translatable into English or French via google translate or better still DeepL Translator) of the famous Russian DIYer Snorry revealing us all that there is to know about isodynamic drivers of planar headphones, as the necessary thickness of the membranes, the optimal shape of the magnets and the magnetic circuits used.

https://www.homecinema-fr.com/forum...ues-kennerton-voir-post-1-t30059943-9810.html

A must read to get a solid technical opinion of planar headphones (and their drivers) that goes beyond a simple marketing.

Thanks Philippe for these links (copied below), which I read with pleasure.

Then Im sure that the clarity and soundstage of the Gjallahorn JM will suit your better.

Please share your thoughts if you decide to get one.
