Maybe someone with more Experience with various gourmet headphones and gear like @pataburd would be kind enough to share his impressions of the Mikros 90s and the K340's. He has very good writing skills and impeccable taste.

my dear friend,

The only difference between my K340 and yours and my sextett and yours is the way i modified them....

First : soundstage of the sextett is inside the head for sure as all headphones i listened to.... But the soundstasge is way bigger...

Second : imaging of the sextett is way more detailed and differentiated....Not even any comparison...

third: Timbre sound quality is more natural with the sextett... Why : because of his set of tuned resonators inside the shell the bass depth and extension and his mass is way more important...

Then the difference between us is reduced two two possibilities : i am deaf .... Or your sextett are not drived as mine with which are improved by my internal addition of two damping materials externally and internally to suppress resonance...

i remember that you claimed in the past that the sextett was on par with the K340 and thank to you i even bought the sextett to TEST and VERIFY your claim...

i am glad to have bought the sextett thanks to your recommendation ... i optimized them and modify them my own way and i am glad to have a secodary pair of very good headphone NOT FOR MUSIC but for my late evening movie ( my wife hear noting then ) ...

The sextett contrary to your claim which i test by buying them do not compare at all , so good they are to the K340 hybrid with a bass depth and extension way better and better high frequencies and more than that an "out of the head natural speaker-like soundstage" wnhen the recording is in great hall and church and well done.... No other headphone i know touch them....Certainly not even the sextett which are my second best headphone ever ...

But you can think i am deaf..... Why not ?

Acoustic parameters are not about "taste" by the way..... For example if you had read the Dr, Gorike patent you will know why these tuned resonators makes the sound impression of the sextett and especially of the K340 so realistic...

I read it and as you know though my 35 pages review of the K340 i takes 6 months to figure it out the way to use them right...

I dont think i am deaf .....

Anyway i thank you sincerely from my heart because without you i will never had bought the sextett ..,. I did not needed them after the K340 but i would had never experimented the acoustic effect of these passive resonators on a singular dynamic membrane if you had not push me to buy them to falsify your claim ...

I sincerely thank you to for the Mikros recommendation also .... It will be my son birthday and it will be his gift, they are very well stable on the head and isolated well . They are not bad headphone. if they were i will sell them. They are not in the league of the sextett well optimized thats all .... They are so far away from the K340 i did not even understand why you like them so much.... but without you i would had no way to know that and how much efficient were my six K340 modifications compared to yours ...



i hope we will stay friends.... I am very direct person ...

Richard,
I stand by my Experience and opinion of the Mikros90s. IMO, They are a very detailed, engaging and balanced headphone. I will state again, " IMO, The Sextett are not even close to being in the same tier as The Mikros and K340's" To each is own. Our preferences for certain attributes of and musical tastes are obviously very different from one another.
I think I've had a bit more experience with a variety of headphones than you may of had, so I'm not talking from the inexperience, as you may have been implying to.

You haven't even had them for a day. Have a little patience and don't be so quick to judge something you haven't really had a chance to experiment with.

P.S

Have you had your hearing tested recently?

 

[richard51]

The K340 cannot be used without some modifications...

Remember that when i bought them it takes me few modifications to even like them...

Then it takes me 6 months to learn how to use them...

Reading your comment with non modified K340 which you use as they are "right out of the box" with different gear pieces it seems yours are not at all like mine.... I opened mine cut the plastic grill, put damping sorbothane , FoQ T32 tape, i use a specific amplification, a specific EQ , i use very specific vented holes pad, etc ....

Maybe someone with more Experience with various gourmet headphones and gear like @pataburd would be kind enough to share his impressions of the Mikros 90s and the K340's. He has very good writing skills and impeccable taste.

@pataburd WHO is that???

 

[richard51]

My son has already bought his headphones.... Said my wife....

I will sell the Mikros 90 in mint condition with original pouch box + manual + 6.5 mm adapter , for the price i paid : 70 dollars +postal fees ...

my friend Davidzak64 would have the first choice...

 

[richard51]

I made a miscalculation sorry :

I will sell the Mikros 90 in mint condition with original box +original pouch protective bag + manual + 6.5 mm adapter , for the price i paid : 73 dollars and the postal fees are INCLUDED with a tracking in this price ... Exact cost i paid for ....

my friend Davidzak64 would have the first choice... I only wait for his answer before official selling advertisement ....

 

[pataburd]

Give him a few days. He has been busy lately.

 

[richard51]

For sure ... I will not sell them before he decide in a way or in another...

 

[Davidzak64]

For sure ... I will not sell them before he decide in a way or in another...

Thank you for the first offer. How would you like to barter your Mikros90 for a mint pair of Sextett LP version? If not, I would gladly buy them from you, but it will have to be in the later half of April.

I prefer to sell it because i had already the sextett for my computer system dedicated to movie.... For sure i will wait for you to be ready ... No problem for me they wait for you in a drawer i will not use them anymore ... Just send me a note when you will be ready ... take the time necessary you need to adjust for your budget my friend...They are reserved for you ...

The best for you in this Easter week-end ...

 

[Davidzak64]

@richard51 do you use EQ APO? FYI, the Mikros 90 are the most head placement dependent Headphones I've ever used. For me to get a very consistent fit for the best possible experience, I put them on backwards and reverse the channels in the EQ APO effects tab. You may want to give it a try, since you like to experiment with mods.

The Mikros is a good headphone in my book ...
it is very well balanced...
Isolate very well and is stable on the head...
For the price it beat many headphones...

But i bought it because you said it rival the sextett and the K340...

mine are heavily modified and optimized...

There is no comparison ... The position on my head or EQ cannot change that ...

The two AKG the K240 and the K340 secret is their shell acoustic resonators devices ... it gives to the sound a realism that makes all my other headphone a place in a drawer...
I did not sold my other headphones because they are all modified...

I sell the Mikros to you because i listen to it less than an hour ... I will not modify it and touch it more, it is a mint pair...
...Even if i did it it will not beat my K340 which is the only headphone i used for music with my modified speakers... I bought it only to verify the difference between your sextett and yoour K340 and my modified one.... The diference is huge if i trust your appreciation of the Mikros which so good it is cannot rival even the sextett modified with resonance elimination and well driven ...

It's kind of bizarre how great those relics sound.

 

[richard51]

it is not bizarre the K240 is made with a set of passive tuned resonators inside, it help for the bass but more for perceiving spatial qualities as in imaging. And the timbre is more natural...
It is why i prefer my K240 to all my other headphones ...
But i inserted on it and outside materials to damp it and attenuate any resonance of the shell chamber ..

The K340 is on another level completely for me... I modified it more to make it work optimal... Inside too there is a set of tuned passive resonators but the shell here is a dual chamber and act as in a room the reflected waves so necessary to recreate spatial qualities from speakers...
the K340 crush the K240 in timbre naturalness, deep bass, and a stuninng "out of the head" perception when the acoustic recorded album is done in a well control hall or church in particular...it is better than most speakers...

I only use the K240 so good it is for documentary and movie... For music i use the K340 ...There is no comparison between the two in spite of the same tuned resonators technology... Two working cells instead on one made a huge difference.

But BEWARE there is no comparison between the K340 non optimized right out of the box and mine ...It takes me 6 months to reach this level.... It is the more complex designed headphones . An hybrid with 5 tuned resonators, two cells one dynamic and one electrostat, and one crossover all that distributed on a line which create a dual chamber . Creating this headphone costed time and money and a genius , Dr. Gorike a physicist and an acoustician founder of AKG . It is certainly the best headphone they created ...I dont even need to hear all the others...

I asked a person working for Kennerton the Russiam creators of many TOP headphones why they do not make an hybrid like the AKG K340. he said to me they tried but abandonned it because it is too costlier in research if we want to create a TOP product of this type , too costlier to assemble and not enough profit at the end process .

Then i learned why AKG K340 is and was the only hybrid on the market ...

The Dharma do not compare because it is a dynamic cell with a supertweeter working way over 10,000 hertz if i remember it is not really two cells working together around 4,000 hertz one over and the other under 4,000 hertz.. And there is no complex dual shell chamber with 5 passive tuned resonators to make possible a perfect separation between the mids and the bass ...And the K340 goes very deep ... I felt the bassier note of an organ with my feet and body by bones resonance ..

I disliked all headphones...

The only one i can like is my K340...

By the way i tried to upgrade my top Sansui Au 607i from the alpha series and bought one of the best tube amplifier for headphone on the marketto drive it. i lost much money with the cost of the return fees. The K340 ask for a powerful but very synergetical amplification.. This is all the reasons why there is few negative reviews of it by people who tried this old 40 years old product without understanding how it work with the wrong conditions. But the positive reviews are way more numerous for sure.

i think only perhaps the RAAL could beat it ... but i paid the K340 100 bucks and i am not sure at all that the RAAL will beat it on all aqcoustic factors : deep bass , natural timbre, "out of the head" soundstage... Then i will die with it ....

It's kind of bizarre how great those relics sound.
