Cable Goop Review George is going to freak!!

The only practical way to do this if you have a system driven by 2 mono block amps. Treat the left channel with NPS 1260 and the right with another product. You will be able to compare two mono audio signals with one another by switching off one power Amp at a time. Maybe not a perfect scenario but definitely the easiest and most accurate way to actually ab the product. Both my systems have been treated and there is no way I am going to wipe that magic stuff off but I am willing to visit someone on the area to do or demo or maybe a/b the product. I am not affiliated with the company so this offer is purely to help some of you in the decision process. 

Or if you have the same untreated audio cables as I do..both AC and single ended..I wont be doing that swap because I know my system well enough that I won't waste my time on what I already know.
Will instead apply to the internal connections of my amp next week.

Come on people, I can certainly tell when my system sound has improved.

Sure @ozzy you can on your system.But not having a baseline to compare someone coming to your house for demo is not the same. That is the context here as a member was kind enough to offer coming over to hear his gear. Needs to be an A/B test to be valid.
