After buying 2 more cables it seems that Trifield works fine with other sources. The problem I had was resolved by using a different DSP preset (music I think) with that source.

Thanks again for your advice, I will be tweaking it soon, but I’m just enjoying having things working again for now! It Sounds great already and will be awesome when calibrated.

I want to replace the centre with 5000HC/5200HC or even 5500HC if I can get one locally šŸ™‚

The sub is also working.
