Pros and cons there, the V10 does run a balance shaft which is literally designed to tackle balance factors - both primary and secondary balance factors.
The flywheel/crank pulley keeps inertia in the engine as its spinning. A very popular mods for motorcycle racers is to remove crank flywheel COMPLETELY. I have done this and then gone down the CARVE kilos off cranks also. We took a 25lb crank and flywheel assembly to around a 10lb assembly. The change was night and day - the willingness for the engine to rev was incredible. Down side is its weaker (crank was as we carved soo much off) and it was far harder to use the power. Hears the kicker…dyno results are 0…naaaddddaaa, you get essentially zero hp from it, its simply a response change. It also made it far hard to get off the line (bikes cant be auto and wheelie pretty easily compared to cars …)
That triple filled damper would defo make slower engine speed vibes lower, it would possible help with the super low end torque that the V10 makes - audi can probably run a more raunchy low RPM cam setting/profiling with this style of damper. If you use your S6 to tow etc the lower end will be better with the stock damper… The higher end rpms are where the balance shaft does the work. I.e my bike with the super light crank had more vibes at 4,000rpm than at 10,000rpm.
Everything is always a compromise - brakes and tyres are the perfect examples, better ones last less, they have to to work better at the higher level your asking of them.
