About users with hidden agendas

I thought dealers, designers and manufacturers are expected to identify themselves...not sure if it is an actual "rule"...

you can also very politely state whoever you know is a manufacturer or dealer, so all can know...whoever you are referring to likely knows the "rules"

I believe everything matters. It often comes to what you have the time, interest, inclination and money to do. Though I always consider resale value an important part of the decision. many cables and isolation devises lose almost no value over a few years.. I have experienced significant improvements from cords, cables, isolation...have never tried fuses, they would probably help, and I’m tired of trying different cables, just can’t get on floor anymore...and it was the Synergistic Master Coupler that got me started on power cords, sold it for no loss 10 years later...
