Well I am a "Noob" here but I have tried and kept the SOtM sNH-10G and it made a huge difference in my system. Yes I could hear the difference. There have been many things I have tried over the years and returned as it made little or no difference in my system.
I simply am not that arrogant to say what you hear in your system is false, or you are under the influence of marketing, hyperbole, or a placebo effect.
There are far to many that speak, write and youtube of the positive effect these switches, cables and tweaks have made in their systems and only really one Linus (than God). Believe what you believe but do not call out the majority.
Be careful Humpty you will have a great fall.
