Hi everyone, First of all thanks to @ChaChaRealSmooth for giving the go-ahead to post here! Most may already know- I’m Jupiter, and I’m the guy currently making the HD650 and HD600 mods that are known as the JAR650 and JAR600. JAR is for Jupiter Audio Research, and honestly it’s more of an in-house name than anything else. Half serious, half frivolous! (Honestly I think I’m still far from Industry.) I started making the prototypes around 2017 and along the way so many people have pitched in and helped me out that I wouldn’t want to call the headphones my own work/creation. Definitely it would have not been possible without the kind souls I’ve met in this community, and also the incisive criticism from those much skilled than me. (You know who you are!) When the design got finalized there was a loaner tour and I was really happy that people recognized the hard work everyone put into this. It was really great, until starting in 2020 I’ve not been able to make practically any because of the COVID situation and on top of that, mandatory military service. Now though, it looks like the situation has gotten better (in where I am, anyway) so I can now make a few pairs (albeit in a much lower capacity than before). It’s moreso that I just think it would be great if people who want to hear this thing can hear it, instead of me trying to sell more pairs. (Despite how much fun making each pair is, it’s really exhaustive and it’s not something I want to be doing all the time! Last year I was doing this on top of a ton of exams and that honestly had made me really stressed about having to make these.) So depending on the interest Chacha has kindly said a loaner tour can be made. And also I just wanted to take this time to write this thread so that I can stop being a mystery man and help out if anyone has questions for me. Thanks!
