"Line Magnetic Audio is a highly respected Chinese audio company. It’s not your typical “China Come Lately HiFi Company.” They have a well known history for repairing and restoring classic Western Electric gear. The fact that the owner of LMA is an ardent collector of historical audio components is part of the reason these replicas are so faithful to the original; the attention to detail is stunning. They produce amazing reproductions of Western Electric’s electronics, horns and speakers; some of the latter have been adapted like these to use field coils." -- from another website
