@anzaanimalclinic . I read your post with interest. I've just invested in the Sotm 7u, based on many positive reviews and comments of the Sotm cable family. I'm hoping it will be my primary ethernet cable that feeds my Zenith Mk3. I realise there are many others I could A/B. However, the ones which interested me (FTA, Laboga) are not easily available or returnable.
I also have the Sotm ISOCAT 7. I did seek the advice from Sotm before buying the 7u. Naturally, they stated that the 7u cable is significantly better than the cheaper 7. They also advised that the ISOCAT go before the 7u. They're actually pretty good with comms. May Park was very responsive to my questions.
So, I'll have my very non-audiophile Netgear Orbi satellite feeding the ISOCAT. I noted you have a number of switches, including the EE. Can I ask if you tried the EtherRegen, or a decent Fibre bridge? I have my eye on the ADOT fibre package at FutureShop.
