Mikelll, Dev also is leading me down the path of the Sistrum Platforms.
They are expensive , but so are the speakers. Dev said they are easy to install. Did you find that true?
These speakers are extremly heavy, how did you get the platforms underneath ?
On power cords it depends on your Amp.
I started out using the VD Master on my Pass Labs Amp.
I liked it so much I went for the higher model the Rev 2.
I have also used Purist Anniversary, Dominus, and a few others on the Amp.
Most Amps with high power like low gauge copper wire.
