Big fan of TA Cables as an owner for 15 years consecutively. In fact, currently listening to TA Headphone cable now. If you are focusing on TA alone, I have not heard it and cannot help. If you are interested in reference level ethernet, I have investigated because the Zanden 4-box uses an RJ45 terminated digital i2s cable, and after many years of using the Zanden cable, I can say the Z:Axis i2s Reference digital i2s is the very first of a few that has delivered an unequivocal and substantial improvement over the Zanden.
I like the TA ethernet cable it was an immediate noticeable improvement over standard cables. It seems to have a much lower noise floor than standard cable which allows the music to flow. I still use TA downstream in my system but now use the WireWorld Starlight Platinum Cat 8 upstream as it is a bit more life like and dynamic than the TA, but not night and day.
