50 pcbs (non populated) cost Nothing and there are few things on it ! So + 1/3 is a lot...
I find the cheapest buffer version non reflet the good price you keeped low with your first version ! 1/3 more expensive has no sense with 4562 oap (I don't talk about the discrete one ! margin from your side is normal !)!
I believe it's well done for the < 1000 first model, but less for the others IMHO !
Was the NC500 not thicker than the NC400 (at ears) ?

You may try maybe an offer or at least try if not made already this cheap oaps as well:
the famous OPA2604 for a reason !
And the latesT TI/BB but here you will need a soic to dip adaptator.

I remember your work with the UCD modules 🙂 !
You use a very linear tubes ? or one made for its "thicker" sound signature ? JJ, certainly not choosed by luck

Wel done too for the Obligato (and it's cheap) . You sold a populated pcb, a cheap non populated one, or nothing ?
Maybe also a luck for the ones whom can only afford the first version of Boggit ( a good idea btw!).
Do you like more the NC500 instead the NC400 ? Or same sound but just ability to drive the more complicated loads !

When using opamp inputbuffer i prefer the LM4562. Combined with SMPS you need good voltage regulator like HXR or TPS. If not you mesh up the good sound. With linear supply LM317/337 is good enough.
You mean you tried the 2604 already for its smoother signature ? LM4562 is neutral if I remember.
I like the idea of the tube : less stages than an oap... I talked also about this one above : OPA1602 | Precision Amplifier | Operational Amplifier (Op Amp) | Description & parametrics !

Your post does not make particular sense.
I would suggest you try it for yourself its called reality.

I have build/tried a lot of input buffers for hypex UCD oem. Lm4562 is just right for me. The difference between opamps is very small. Therefore i build the opamp input buffer with a dip8 socket so customers can try out several opamps(AD827, LM4563, NE5532, TL072).Difference between tubes and opamps is bigger.
Personal i use unbufferd Hypex module. My sources all have 9Vrms output voltage . In between i have passive volume control/ input select. I have good experience with less parts is more sound.
Driving complicated loads the UCD700lz oem is the best for less money as ncore.

I've heard it's pretty good though its more expensive than the NC500 by around 200 euros for a pair. I've built UcD 180 400 and they are also extremely good though there does not seem to be any call for them. I can do a UcD180 for £499 and sounds amazing I've not had one enquiry! They would easily outperform a Arcam FMJ19 Rega Brio R! Mad.
I lot of people do not know the Ucd700lz, i use them if the nc400 or ucd400 does not perform good in bass control of demanding loudspeakers.
Price wise the Ucd700lz oem must be cheaper then the nc500.

It makes sense ! Thank you for this answer.
So any significant différences at ears on a same load between the NC400 & NC500 ? All the Nc has the same sonic signature ?
What is the factor to choose one of the two ?
My complicated load would be a Kef 104/2 : simple on the paper bu the speaker is in reality a vacum cleaner of current due to its complicate filter and number of drivers. Some says it needs more than a Quad 909 and gave it a Bryston 5B (the 4 being not enough for the plain capacity of the speaker).

plus we can add our own improvement in my case discrete Burson V5 and Sparkos Labs Op Amps along with Hypex HxR regualotors the difference is dramatic.
.
I believe this was your first post here. And we don't glue anything! And its Nord not north, Norwegian for North.
