Sure @DenverW, I'm waiting for it to be delivered. Might be able to get to hear it in next couple of weeks 
Can't wait to compare the RR1 against my STAX Lambda series and 009BK

Just wondering if anybody knows , can these or any Stax pro bias can be used with the older 230v non pro bias amp or adapters If so how bad is the sound going this route.

I have a Koss 95x so if you’ve heard one in the past or have one that’s the comparison I’m dying to hear. Especially since they’re both priced at 500.

Yes a comparison would be nice. Just remmeber the Koss comes with an energizer, the Kaldas does not. You will need to factor in an amp.
So true! Luckily I’ve packed away the Koss energizer and I’ve been using a woo audio wee with a Koss to Stax adapter cable.
It works really well...but this is new!

Wanted to share this, here's a one-off RR1 we made for a Customer through our Bespoke program.
Some more updates -
1) Our Production is coming along, we will be taking orders through our website in a couple of months, again no date yet.
As mentioned before, it's hard to Manufacture the RR1 so orders on the website will be variable with stock. We will only take your order if we have it in our Inventory.
2) Next month I'm flying to Bangkok to meet with a very special person, a personal Hero of mine and a very important figure in the DIY community. He's an Electrostatic Maestro and he'll be getting his RR1's soon.
Beautiful! They remind me of something out of a James Bond Movie! The Man with the Golden Ears!!!

The common agreement in the Head-Fi community is that in order to fully enjoy the Koss - you need a good eStat amp... so I would say: factor in an amp either way

Yep, not gonna do you any good to have a great headphone with no amplification or subpar amplification.
Electrostatics is the highest technolegy in headphones world!,So true! Luckily I’ve packed away the Koss energizer and I’ve been using a woo audio wee with a Koss to Stax adapter cable.

But it have the most expensive price in headphones world.
Koss seccessfolly made a good amp+headphones for cheap price,
but with cheaper materials that made it still good for usage and really fair product.
but much cheaper feeling then any Stax headphones,
and some dissadvantage on sound quality and much cheaper build quality then any Stax amp(energizer)
So, for better sounding you have to spend more money on good amp.
*woo audio wee is a transformare energizer that having the same quality as your speaker amp. not difficulty build (but transformers cost lots of money), but still not worth for independent amp for electrostatic-headphones for price of $ 600.
Compare to RR1, Koss have cheaper features as:
- cheaper headband.
- build in cable.
- short cable (with too long extend cable).
- plasticy light feel.
- ear pads fair quality but not overwhelmed, most prefer to replace them.
- most prefer to buy some Stax or other amp with koss from the begining, better build quality + beter sound quality
I sure that RR1 having less plastic feeling then Stax l300 (most metel parts), and better headband and pads then Koss (like Stax)
and beter design then most of them.
after saw this pictore on DIY forum here I start to understand the dissadvantage of plastic thin headband

In fairness to STAX, the premature failure of that Headband might have been due to improper handling by the user.
Plastic or not is irrelevant when it comes to Stress/Strain, the Headband was definitely torqued beyond it's Tensile Modulus.
The thing to worry about any Thermoplastic is Polymer degradation more than anything else.
Although, the RR1 is Spring Steel and billet Aluminium, there is one part which is ABS. It's a bushing to aid the articulation between the Yoke and Main assembly of the Headband and like any Thermoplastic, it will never last a lifetime. Thermoplastics were originally and still are Engineering materials supposed to work in a time frame and replaced after a certain time.
Given that looks like an L300, it's definitely premature failure. I have old Sigmas and Lambdas with original Headbands that haven't cracked.

Is there a possibility to 'book' the next pair or somehow get into the queue? I'd love to have these headphones and compare them with my systems (modded Stax L300, HE560 and some closed back ones).
Think we’re all in the same boat with that request.
Personally, I was tired of waiting and did not want to wait more than 6 months, I bought a Stax L-300 Lt and I'm happy with it.
