NOt that you arent busy
Could not see a pdf in their site yet. Interesting for capacitance when I read the green promo stand, and I like the metal can. Noise is not spectacular, but we can parallel. Do they give out design samples?

Any particular brands for the caps you would recommend? Something that doesn't break the bank but provides good performance.

Vishay MKP1837 1% will sort you out very decently and are small. Get some polysterene 100pF too to add on the 15n one up to the recommended value or to play by ear to your taste.

Can you see the datasheet in their website?

I know this is highly subjective, but would capacitors like multicap rtx or sonicap be a substantial improvement over the vishay 1837? For output cap I will be using an obligato gold.

Also, are carbon resistors really that better in the circuit? I could go with those Takman ones suggested in the PDF article as they are about the same price as the vishay dale 1%' but I would have to get some more for matching.

-Never directly compared those types, don't know.

-Prefer Dale to know you where you stand. They are good in all areas.

What capacitors do you usually use in your simplistic?

Depends on budget. From 5% industrial MKP sorted out in the LCR to matched NOS American Teflon I had used. Even C0G once and they did fine. Usually trimming the HF 15n base cap with polysterene or silvered mica. Most influential is the interstage coupling cap IMHO. But the RIAA caps must be good for value and not lossy types before thinking coupling caps.

Nice jig circuit for characterizing many JFETS faster this one looks like by the way:
