  1. Here are some photos of a recent Bespoke unit we delivered -
  2. Yes, in that case we have been in production since last year and have crossed over a hundred units in the production mark. It's not a lot but, this is passion not a business. In terms of refinement, refinement to minor fixes have been done. As @JoaMat had pointed out last year regarding the connections, now it is a fully soldered connection from the earlier screw down one. This solved majority of the issues we had in the early units. Then upon Spritzer and Wachara's recommendations since last year, the drivers have 2-stage dust protection and go through vigorous anechoic chamber testing to detect noise/buzz/squeal. We have positively eliminated that as well. Lastly, the overall assembly and Manufacturing has also been refined now that we have been in production since last year. The RR1 is here to stay, it will not be updated as "2.0" or a "2nd Gen" as other Manufacturers do. There will be future products coming out but, that's another story as we are currently busy with other non-headphone related projects as well.
  3. There is an active HF thread if you're interested. I try to limit my postage here on Head-Case as I understand most people here are happy with what they have and are not interested in further marketing posts which nobody cares about.
  4. The re-recorded version by Lalo Schifrin.
  5. Interesting, not sure how the bolt would come loose. Stators are now laser-cut Brass, you can directly solder onto them if you like. The front Stator connection might be challenging due to packaging reasons but it is workable if you want to solder it and not use our bolt method. Furthermore, every part of the Driver is serviceable because it’s all bolted and no glue is used. Spacer is Aluminium though.
  6. Jose, around one more week. @morphsci @JoaMat Not to burst your bubble but DHL is too optimistic, custom clearance causes around 2 days of delay in most cases.
  7. Yes, those imperfections of the Aluminium on Todd's headband is indeed correct. There is a story behind it though, mid-way in our production our Anodizing guy decided to go rogue. The finished parts weren't dark enough and for some reason he was not able to rectify it. We were left with some inventory that was fair but far from perfect and as a small Manufacturer, we couldn't afford to scrap it. Eventually, we did find a reliable Anodizing company and have been working with them since December albeit, they are interesting to deal with as well. This leads me to believe either there is some money to be made in the Anodizing industry or the entire industry has undercut itself beyond sustainability. Furthermore, we made some changes to our tool-paths as well and have added an additional facing operation on all sides to improve the surface finish without needing additional processes like brushing or sand-blasting. This may seem like something to do since the beginning but since we don't have a 5-Axis that we own, it adds more machining time and lowers our output even more. Every single part is made in-house. We also have transitioned from 3D Printed Earcups to full Injection Earcups. Again, to improve our production rates so we can focus on things that are more delicate and intolerant. Anyway, I do take the responsibility but just wanted to share why. With vertical integration although QC is in our hands, it is challenging to be this stringent at this price point especially when you are running out of Capital.
  8. This weekend I flew down to Bangkok to meet the man himself, Wachara. For me the the entire RR1 Project was a dream - to develop a fully in-house Headphone with Bespoke parts specific to the Headphone and to meet my Heroes along the way. RR1 has enabled me to meet some of the greatest people in the Industry worldwide and that's the only success I see in the Headphone. Everything else to me is irrelevant. With Wachara, I've met all the Heroes I wanted to meet and that ends the RR1 chapter for me. Kaldas was named after my Grandfather and our goal with the company has always been quite diverse. We started the Headphone project knowing we would be in financial turmoil by the end of it and that is indeed, the truth. I will be managing our Headphone division not for long now, as we expand our production and settle the Manufacturing, the responsibilities will be handed over to one of my longest serving Engineer who was instrumental in the RR1 development. I will divert my attention to some of my other dreams. Thank you to everyone whom I've met along the way. Those memories will serve me well for a long time. Where it all started for me. Visiting G.R.A.S. in Denmark Meeting Birgir in Iceland At Audeze HQ in Los Angeles Klippel in Dresden And finally.
  9. Not yet but I have been in touch with Wachara from the beginning and will be visiting him in the coming months. He knows! Was going to meet him sooner but a lot of travel came up and now I'm sorting out some production related stuff.
  10. Hi, Yeah, so this is what I had at the booth - So, this was only there as a precautionary measure as the wires on the RR1 are exposed for an aesthetic purpose. Nobody is crazy enough to do it (Stupid design but, did it cause I like it) so I just wanted to make sure nobody accidentally shoved their hands inside. It's all insulated so there's not much to worry about but again, just a precautionary measure and the intended method to properly handle the Headphones. In the end, the classic male mentality won "I know what I'm doing, instructions are for pussies" and hence that leaflet was mostly ignored ? Thanks a lot for stopping by!
  11. Just wanted to post a quick update that I will be in LA for a certain Headphone show this coming weekend. I hate marketing posts and I am very grateful for Head-Case to let me post without asking for Sponsorship or just simply deleting my posts. So, I will respect that and will leave it at that. If anybody is interested and lives in the area, please feel free to test the RR1. I will have the KGSSHV, 252-S and E/90 with a STAX adapter to cover from low-end to high-end.
  12. Are you sure about that Birgir? Last time I heard, a guy name Ralph or Rafe said you need at least a couple of days for "Electron Alignment" , I suggest swimming across the Arctic ocean for 3 days as a final measure as well.
  13. Today was a very special day. They say, never meet your heroes but today I met the man, the myth, the Legend of the Spritzer. I flew down to Reykjavík to deliver the first production RR1 to ever leave Indian shores. It was an honour to meet Birgir, I still remember reading his posts 7-8 years ago when I got into the hobby and owning an Electrostat seemed unfathomable. So, delivering my Headphone to the STAX Mafia is an occasion to celebrate. Had commissioned 2 custom KGSSHVs. Our primary Amp of choice for upcoming shows. Really fortunate to be lucky enough to visit Iceland. Even though it was a short business trip, will be back with the family someday.
  14. Thank you for your kind words!
  15. Not ready for official orders yet. I am currently delivering a couple dozen units to some of our local customers who have placed their orders since last year. Birgir and Wachara will be among the first to get theirs internationally, hopefully by the time their opinion is out we will be ready for international orders. Will be an epic fail if they don't like it.
