EDIT: Looks like we have enough for the minimum order, please commit by Sunday 28 March 2021.
Over on the AD1862 DAC thread there's been some interest in high precision resistors for the I/V section. If there's general interest that yields more than the minimum purchase of $250 I'm willing to put together an order of General Resistance GG102 Squaristors at cost.
Full disclosure: I padded the chip GBs a little to cover fees, have simple worldwide shipping costs and some supply in case things were lost/broken in shipping. The resistors will be all custom, so no backup stock but also lowest possible cost. Unlike the chip GBs, I won't be doing more than one of these.
The resistors are made by General Resistance (actually Prime Technologies) and sold in Europe by Rhopoint, they seem to be better known by that brand.

0.025% accuracy raises these prices by 25%, 0.01% accuracy raises by 50%
There will be some shipping cost from Prime Technologies, TBD based on order but would be spread across each resistor and doesn't apply to the minimum needed to make the order.
Shipping to you can be in a regular letter envelope by first class mail in the US or rest of world, at your risk without tracking or insurance. Priority mail and other services to add tracking and insurance are possible - starts at $7.95 in the US and $14.50 rest of world (including Canada, sadly).

wealas, by my math that's 4 x $17.15 = $68.58. We might be over the line but I need more specifics.

Hello Paddy, may I ask you whether these resistors are 0,5W in spec and whether a custom size (i.e. 133ohm, 0,01% accuracy) would be feasible? Thanks a lot
From the docs I was sent, the GG102 Squaristor is rated 0.30W. Certain items in the Econistor axial-lead family seem to be 0.40W, but no 0.50W.
Custom resistance and accuracy are feasible, but I would have to ask how that affects the whole order (ie, do we all wait for a custom piece? Or can the order be separated?).
A 133R 0.01% resistor would be $24.45 * 1.5x for 0.01% so $36.68 per resistor in quantity 1-9.

You won't be disappointed.
I have them in my DDDAC1794 and they are the best I have tried in I/V position.
Looking at Rhopoint's listed specs, the only difference I can see is that the GG102 is RoHS-compliant and the GR102 is not. Non-RoHS is apparently available as a special order with a 5% premium.
Paddy, pls count me in for 4x120ohm 0,01% accuracy 0,3W Rhopoint GG102 to Italy, will remain waiting for your contact via PM, thanks a lot
I'd like to know, too. Aside from the packaging differences there may be little difference between the 8E16 Miniohm line and the GG102, since they're virtually the same price.
The 5G10 Econistor is substantially less expensive in the lowest resistance range (9.97 vs 18.41) but less so in the upper ranges. Specs show less stability over time than the other lines.
We can order any mix of products, I'll add the pricing if so.

With geoturbo's interest we're definitely over the line. So how about an ordering deadline of Sunday, March 28?
Thank you Paddy for putting yet another GB together 😉
I’m definitely in for one pair, maybe two. I’ve got to dig into their offerings and see what will work for my needs.

I’m going for:
luchoh 2100R 0.1% 18.41= $36.82
I’m still researching for another pair, but if time doesn’t permit me to finish my research by 3/28 - this is my choice.

Hi Paddy,

Hi,
...if this groupbuy is still possible and payment by Paypal is viable
I would like to add myself to the list:
4 x 1k0 0,1 % a 7.16 $ each = 28.64 $
2 x 100R 0,1% a 9.97 $ each = 19.94 $
2 x 1k5 0,1% a 7.16 $ each = 14.32 $
2 x 10k 0,1% a 7.16 $ each = 14.32 $
Total before Paypal fees ,p&p and handling : 77.22 $
(Post to Germany)
Thanks in advance
