Well, it's a pity people are taking this personally, it's really a technology and business decision.
So first: if we make a new connector there will be two-way interoperability with all existing headphones and amps via a simple adaptor.
Second, it seems people are making some big and wholly erroneous, assumptions about WHY we are doing this. I'll address the "sacred cow" question first; just because something has been in use for decades does not mean it is ideal.
- Stax has made 'stats in volume and presumably their plugs work for them and are reliable so they have no motivation to change. "Unchanged" and "reliable" is not the same as "ideal."
- There is no supplier of quality, volume parts we can find (This is an engineering project, not a religion! We're human, maybe we missed a great resource for affordable quality parts, if so help us out here!)
- The plug has a large diameter, bigger than an XLR. We believe more electrostatic headphones will create demand for portable gear and a lower profile connector will be needed at some point anyhow.
- The current Stax plugs expose live voltage when inserted or removed from an amp that is on. Obviously turn off the amp for safety, but that is not foolproof (I've zapped myself, so maybe I'm a klutz)
- The current plug assumes the modern Stax voltage, 580V. It is conceivable other voltage standards may arise if more vendors join the market. If everyone agrees to stay at 580 this is a non-issue, but it does limit options and imposes design constraints.
I don't think we are taking it personally, and of course it's your product and you can do whatever you want. But to be fair the only reason you gave until now was to make a connector that is "more modern, stylish, and obtainable" because making Stax connectors is "silly, time consuming and expensive." None of which really implies that there would be any technical advantages to such a connector. I think our criticisms were fair given the information we had to work with. That being said, now that you have elaborated on your reasons I can understand where you are coming from.
I still don't agree that a new connector is necessary, and I still think that you would do a lot more to help the E-stat community and amp builders by ramping up production of a high quality and affordable Stax compatible plug and socket for both your headphones and any other vendor or individual who was interested.
If you or anyone else intend to sell adapters then the issue of obtaining Stax plugs and jacks is still present no? How will you make adapters if there is still no source for Stax plugs and sockets? These are serious questions that I think deserve some thought.
So what we are trying to do:
- Lower profile to enable slimmer portable amps while provide robust build quality for desktop amps
- Additional "free" pins for future bias voltage standards
- Easier insertion and removal
- Hopefully a locking design
- Available in volume to anyone from neutral parties who make the parts (we'd not be getting royalties nor would we be in the supply chain so as to ensure a level and fair playing field, we do not believe anything about this should be proprietary or bias towards one vendor)
This could be a good thing, but it also concerns me to a certain degree. If this new socket is to become the standard for a new generation of electrostatic headphones, who will determine which pins are used for which bias voltage. Will there be a governing body who makes these decisions? Will future headphone and amp makers decide this on an individual basis? How will it be ensured that every amp that has this socket will have all of the potential bias voltages wired to the same pinout for this new wave of electrostatic headphones?
For differing bias voltages I'm actually more in favor of incompatible sockets, because that at least ensures that you cant plug your headphones directly into something that could fry them.
As for the last bullet point, I think that's wonderful, and I commend you for wanting to stay out of the supply chain to avoid conflicts of interest. However I can't help but wonder, If there are neutral parties who see a viable market for something as niche as a connector for electrostatic headphones, wouldn't it be lower risk and more profitable for them to produce connectors that interface with an existing standard that has near ubiquity in that market?
I mean no offense, this is just one electrostatic headphone enthusiast and potential future customer's opinion.
P.S. I actually don't consider a proprietary connector to be a deal breaker. I happily owned a pair of Koss ESP-950s for over a year and used an adapter to listen to them on my SRM-1 MK2. I just don't prefer adapters when they are unnecessary because I find them inelegant.
