My experience with re-clockers (non professional) is just Audio-GD and its been a jolly ride. Im not the guy to compare brands but I know what good sounds like.
My upgrade path has been this:
1. NFB3: nice
2. NFB3 + V2: a mild improvement, probably more mental self reassurance than actual
3. NFB3 + V2 + PSU: that first significant improvement that I wasnt expecting and piqued my interest
4. NFB3 + V3 (#4) + PSU: kinda disappointed - had me reaching for the EQ to tame the highs which is something I dont like to do
5. NFB3 + #5 + PSU: amazing. faultless. I never thought my dear old NFB3 could sound this good. Bravo Kingwa.
6. NFB3 + #5 + li-ion battery: about the same as above - honestly could not report a noticable difference. If anything a smidgen more "analogue" but dont go out of your way to find a battery over the PSU.
Thrown into the mix was the new HE-500 to go with/replace the old K702s but I kept referring back to the 1964q on the daily commute to reset my audio memory.
Also FYI - the PSU ran worryingly hot until I applied the resistor tweak to get it to work with the V3.
So yeah - I know the NFB3 aint the be all of DACs but to illustrate the worth of the DI series its been perfect. Pairing it with the C2.2 via ACSS was a good move too.
