    Wachara, Total area is 80 x 70mm, well...79.90 x 69.90mm to be exact. Diaphragm is a in-house sub-2 Micron PET. We tried 600Nm but due to the poor Young's Modulus, it was almost impossible to tension and/or get any decent bass. To successfully use a Nanometer film, I personally think the Matrix requires better filler geometry to improve the Young's Modulus but, with current Polymer technology it is difficult to produce such filler based thin-films at such thicknesses. Diaphragms are manufactured by our other family owned Polymer company.

    Hi Aumkar, Wow, 0.45 mm D/S distance is nice. How big is your diaphragm? Wachara C.

    We will be exhibiting at a certain Headphone show in SoCal this June. I think by then I will start taking orders. I didn't do any pre-orders because I don't like holding my customer's money like a lot of other companies. I will only take orders when I have enough inventory to sustain a ship within a day or 48 hours policy. Currently, production is my main issue as all our Stators are Aluminium and require strict dimension accuracy while drilling. Aluminium unlike FR4 can be easily bent and cause several non-linearity issues. There are better ways to machine a Stator other than on a CNC but it understandably increases the production cost and complexity. Our D/S gap is 0.45mm and our spacers have a maximum tolerance of 0.005mm measured across 250-200 points which is as good or even better than STAX. STAX uses brass to combat machining challenges, we use Aluminium with more methodical operations. I am trying my best to increase my production output but there's only so much I can do without comprising QC. If I was here to make a quick buck, I would take taken pre-orders already. Regards, Aumkar

    I want to make a cunningly linguistic snark about this, but I am tongue tied.

    Listerine was initially marketed as a disinfectant floor cleaner. Then as a cure for gonhorrea. And finally - pow - as a mouthwash! But I'd sure like to try the Jack Daniels flavour version! And I certainly wouldn't dip my old man in it

    The two AK end links I ordered were delivered today for use with my Rolex Oyster Perpetual 39mm, so just waiting for the strap which should take a week or two.

    I'm interested at the intro price, hopefully there are no snags in their launch

    Hi Jpleg, I don't think that should be a concern. I don't see myself jacking up the price. Let me give you a quick background about me and my Company. My company is "Kaldas Research"- as the name suggests, we are a Research company. Our main Business is contract R&D and Manufacturing. "Kaldas" is named after my Grandfather Mr. Gokaldas Chandan who was a big inspiration for me as he started with absolutely nothing. Making my own Headphone was a very old dream. I started as an enthusiast with my HD650 around 8 years ago, what rekindled my dream was when I visited Beyerdynamic in Heilbronn back in 2015. The factory and family owned spirit of Beyerdynamic was a big moment for me to consider making my own Headphone. I have been lucky enough to visit G.R.A.S. in Denmark as well as Klippel GmbH, all of them had an impact on me in one way or another. As to your concern, why am I selling at $500? Is the Headphone cheaply made? Does it sound like Garbage? For me, it's simple. I am personally sick and tired of the over-inflation in prices of recent Headphones. Most people are trying to get into the Headphone industry to make money. I am not. I think there are better ways to make money than to get into an overly crowded industry. At the end of the day, I'm just a kid with a passion. The skepticism people have is beyond my control. Regards,Aumkar
