Makes sense to me! Don't worry this thread is derailed many times over, but is great because it's still going!
Your TT>phono cable looks good to me. They are shielded which is important with super low level signals. I heard Signal's Silver SCs and they were excellent, just a little bass shy. The website blurb about these ICs says awesome bass, so as long as you're happy with them and they're quiet that's all that matters!
I don't have a lot of experience with ICs for line level signals, limited to Anticable copper, DHLAbs, Belden 1505, Grover and JPS. I happily use all Grover S now, but I will get some JPS SC3 when I can swing it, they are about 8x more $.
