Big Ben and Signal path/mixer opinions

[Razor Blade]

I have both Hedd and Rme 8 i/o. I track through the Hedd, mild processing, into rme 9652---> Nuendo 3.0. I have been mixing in the box but, would like to sum down out of nuendo to 8 tracks, out through the RME 8 i/o into a M3 Tube tracker tl audio mixer, and mix/eq in there. The tube tracker mixer has options for a digital card, of which I know very little about, as to quality etc.

would Big Ben be of help to me to improve the clocking of the Hedd and RME converters (and possibly the M3 Tubetracker board digital card)?
Im wondering if Big Ben would be a good addition to my situation?

Im not familiar with how the big ben would connect to these converters? Does it just use work clock outs from the big ben to each of the converter boxes /cards? or?

Im trying to understand if using this digital audio card for the TL audio m3 tube tracker mixer would be an asset to me, and if also, Big Ben would also be a good asset in my situation.

Thanks
