Personally I would use 100-150 load capacitance + interlink capacitance.
Btw, have you tried the NAD with the same VTA/VTF?

Hello Meper,
Ortofon recommends a load capacitance of 150 - 300 pF for your 2M BLACK LVB 250.
If you say, that your phonocable + tonearmcable has together around 40 pF, then subtract that from
the value ORTOFON recommends: 150 pF - 40 pf = 110 pF (min.) and 300 pF - 40 pF = 260 pF.
Try it and believe your ears! There is no 'golden rule' for that value. It will influence the highs a lot.
I also agree with freebee...
With vinylplayers you can try a lot.
Cheers
Dirk 😉

I adjusted the VTA after I took the NAD out and inserted P3.
The arm was lowered a bit so VTA was reduced (VTF the same about 1.65g. I just finetuned it after VTA adjustment).
Using google it seems that less VTA should not enhance "brightness".
I used google again to find specs on NAD riaa:
"Indgangsimpedans: 100 ohm/180pF (MC), 47kOhm/200pF (MM)".
It seems to be born with 200pF at MM settings. Then maybe I could try with 220pF to start with and check if I notice a difference.
I will later pickup new cut RCA cables (0.4m, 0.5m) + power cables (0.5m). Then TT will go from 1m to 0.5m RCA (so even less pF). The much shorter power cables will make less mess behind the rack system and I can better isolate signal cables from power cables.
The P3 has a Zobel filter to dial-in. But I don't experience oscillations or other kind of instability.

Reducing input R can tame down highs. You may try 39 or 33k (or simply bypass the 47k res with e.g. 150k).
BTW which opamps do you use?

I tried switching in 100pF to my Ortofon 2M Bronze MM loaded at 47k. I didn't hear much difference but also didn't listen long.
With an Ortofon MC in a different system, loaded at 50R, we noticed some high end roll-off with 100pF added. People with younger ears than mine preferred the sound without the shunt cap.
I have prepared P3 with 220pF dialed in. I need some food (dinner) first. After that I will listen to the setup with a good glass of red wine.
Also with trimmed IC's (picture). The ground wire not yet trimmed. On P3 I use a speaker post and I use banana plug in that end. It would be much easier if that was the standard for these connections instead of "fiddling" with those tiny ground screws.

I use banana plugs often for bonding/grounding things together. They are quick and easy.
I use different color banana plugs and conductors for connections to bench power supplies.
Just for grins I use barrel connectors for the other end of the power supply conductors to the DUT.

The 220pF made quite a difference. It took away the pronounced S-sounds.
Now I can enjoy the music. Interesting the difference between various records in relation to groove noise.
it seems the record company Epic use really silent Vinyl. I opened up a brand new SRV record and was surprised how "silent" it was.
I like when there is no groove noise "also" between the tracks. I wonder if it is the master or the vinyl that is responsible for this. Probably both.
No doubt the P3 is a very nice riaa.

Big mistake? Not at all! That’s a small, and easy-to-do stuffing error.
Also, easy to fix!
Everything else looks quite good, thanks for posting all the photos!

Like "measure twice (or more), cut once"...
"Share photos first, correct mistakes and attract brilliant advice... then flip the switch" is a good modus operandi. Especially with these good folks.
