We have had great success with both Magma 1 and 2 slot PCI expansion chassis and Lynx Studio sound cards, both Lynx 2B (2in-6 out) for stereo and surround playback and Lynx 2A (4 in-4 out) for 4 track recording and playback. We really like the sound of the Lynx converters and the ability to add 2 hard drives for storage in the 2 slot chassis. We have used Lynx 1 cards in single slot chassis to run SpectraPro FFT analysis software. All have been rock-solid and have been used with both PCI and ExpressCard interface notebook computers, thus enjoying a long useful life over several computer updates. We use Sager notebooks exclusively and are extremely happy with the Magma-Lynx-Sager platform. Magma, Lynx, and Sager Support have all been especially quick and helpful with the few minor hardware issues we have encountered.
