"I have never installed or removed PCI or PCI-E cards from a computer. I simply followed the instructions that came with the Magma expansion chassis, along with some additional visual help from YouTube. After completing the installation of the cards and making all of the necessary connections to my computer, I hit the power switch and booted my computer. I then opened up a Pro Tools session and was able to play back a session without any issues. Magma is the way to go!! I am astonished at how easy it was to get it up and running."


-Aaron King, Audio & Music Production




"The new chassis is a winner. Plug and Play! Had it up and running with 10 minutes to spare. I can't say enough good things about these guys. They saved the day! Thank you all so much for your time and help."


- Chris Shepard, American Mobile Studio
