For those of you in the USA, the JLI range looks interesting for DIY enthusiasts...

Hi Micolas,
OK,
K67/K87 capsules don't have A and B grades the same way as K47 capsules, because we match the halves for sensitivity before they're put together. That's part of the reason why neumann switched to this design. There will be no B stock k87 capsules in the first place. There will, however, be B stock regular k47s.
I would avoid the use of mic screens, reflexion filters, partial or closed, etc., for use close to the microphone, because they introduce early reflections, comb-filter, distortions of the spectral profile of the microphone.Kaotica EyeBall is no exception. Years ago I built several DIY versions, of different shapes, sizes and combinations of materials, influenced by the hype produced by SE, but they were of no use to me.
Hi Ari,
They don't leave the building if they have these problems because that's what we focus on in our QC. those capsules are disassembled and reassembled, and if they continue to fail the backplates are disposed of as scrap. the issues we have had happened explicitly because they don't cause problems in any of these things. instead it's stuff like spacers deforming over time, come and go shorting issues, etc. these are procedural issues that affect every capsule from a batch and can't really be categorized or sold as b-stock. as an example, this current batch of k87s i have sitting here. the previous batch was unaffected by this issue, but the current batch has vent issues due to the spacers being softer than the previous order i got from that supplier. this resulted in a batch that tested normally at assembly but drifted later. (I have to buy and ship in my own plastic to the die shop and fingerprint it to make sure they're using the right plastic. Lesson learned.)Hi Ari,
I was thinking about k87 capsules that deviate from the class of
tolerance that you have established (FR, capacity, sensitivity, mechanical/ aesthetic imperfections, etc.) and departs from the historical k67/87 sound profile, but they
can be used for different experiments (that can sometimes lead to surprising results)
Many Thanks!
Hi Ari!
i appreciate the kind words. i am... doing my best. making capsules is extremely hard. but things are going much smoother. out of the 200 or so flat k47s i just processed, the only outright rejects (only 1% of units!) were due to shipping damage, and my goal is to make that true in general going forward. these past 8 months have been very punishing, but i am hoping to be out of the tunnel soon. the k47 is relatively easy. it's plastic bolted to metal. when you start adding chambers and isolation, like the k87, things start to get wonky. with each added complexity and different-specified part, the difficulty is multiplied, not added together. that's why the ck12 is such a notorious capsule, you know? when i went into this, i went into it thinking that the k47 was a more difficult capsule than the k67 and k87, because that's what i'd heard from others online, so i felt confident that if we could do a good k47, we could probably do a good k87. i was wrong. the k87 is an unbelievably picky capsule to get sounding truly good under critical listening and working well electrically. it absolutely will not tolerate many things that are totally fine to do to a k47, or even an m7.Hi Ari!
I understand. You are not interested in a certain business model, which unfortunately is more and more common (focused on profit maximization at the expense of quality). Excellent! Nowadays you rarely find transparency, honesty, trust, stability, predictability, respect for customers.
You really want to maintain the highest quality standard, to offer without exception top products, to equal (and why not, to surpass brands with established reputations).
I think, and I'm not the only one, that Arienne Audio is already a big name.
You have our full appreciation for all of this.
Thank you!
yeah, but our machining is already pretty tight so we never really ran into those sorts of issues to begin with
Yes, you have an amazing pedagogical talent, you explain the essence of things very well
I understand perfectly, (I think even those who do not necessarily have a technical education understand the details), in conclusion, let's hope that you will produce the historical K47 in series as soon as possible and even Arienne M7 !
Forwarder is still counting and sorting
Appreciated thank you
