This is not at all my experience with these pickups. I don't find them to be dark, at all.
I don't find them to be a Pure Jazz pickup at all either; they seem to be more like a 51 Precision single coil....bigger broader frequency response all up and down, but, very even.
I don't think they get very close to a Split-P Precision tone iether, at least not without some substantive eq: they don't have that slight low-mid hump P's are known for.
My 5501 has DC5's with taps for single coil, dual parallel (which does an ok P tone) and dual series-which is much fatter and darker than any J sound. It has a Lakland LH3 preamp, and it's very snappy overall. The DR High-Beams contribute to that, no doubt.
The Valenti Geddy Vee has Big Singles, and a Nord 3 band preamp. I can't say enough about this combination. The preamp is very pure and usable throughout it's entire range. This bass really is closer to a trad J sound than the DC5's, but that should be no big surprise as they really are single coil all the way.
I'll pit either of these basses against axes that cost twice as much or more. Nordstrand rules
I would have put the Nord pre in the Lakland, had it been available at the time. The Lakland LH3 is a nice unit and not very colored, the Nord is less colored and not surprisingly a very excellent match with their pickups.
As a reference point on preamps for me, I find the Aguilar stuff fairly un-natural sounding, and that not very much of it's range is usable before it gets ''pillowy or glassy." Sounds nice enough before it does that....Hated the audere, and really couldn't get why people liked that.

If you want P tone, Nord do that very well:
They turned my 55-01 into a low end beast. I literally have to turn the highs all the way up or drop the lows to get any clarity out of it. And the mids are outrageous. I think it has something to do with pairing it up with an Aguilar OBP-3 but where this bass shines is when I pull the passive switch. Roll back the blend knob a little and I have bridge grind and growl for days.
