Try googling RA-1 ever? It's a joke. Probably the biggest joke in Audio history, period. I can't think of any audio equipment more ripoff, more BS snake oil ever in all the time I've been reading about audio equipment. It ranks at the absolute #1.
#1, RA-1 for BS snake oil would be like a satellite in space.
#2, the #2 spot would go to some random snake oil on Mount Everest. That's how massively ridiculously dumb the RA-1 is.
You can build a RA-1 for less than $30 without any prior experience in DIY projects.
