@richtruss,
the EMO filters RFI/EMI as well as ground level noise from long ethernet runs, whether you call or not call that a filter is your personal choice. As to your stated fact that one of these is also built into the streamer: there is plenty of evidence that multiples in series are beneficial and in my case the insertion of the EMO filter was significant for SQ
You will also note that I listed an additional Acoustic Revive filter higher up the list, this has passive characteristics as does your ENO filter.
Btw: you should make people aware that your post promotes your own product.
