What is A.R.T? I have to say this is a little too much for me.

I'm not necessarily a denier but I am by nature, a sceptic.

My B/S meter was fluttering but I wouldn't call B/S on it without more info.

The five layers are:

1. Open wallet

2. Fork over cash

3.  Install into system

4.  Listen for demonstrable difference

5.  Wait for confirmation bias 

im joking really cause I have no idea what this is supposed to do and I’ve made some investments in cables and fuses myself.  It seems a bit like stacking crystals onto components though.
