I've never tested any of those clones. I have a friend that has 2 BAEs and he loves it.
But, as many people here said, they are all kind of close to the original 1073 and they all have have their peculiarities. So I'm probably getting some AMLs and some Auroras, because they are cheaper, well built and sound awesome. Maybe BAE makes the closest clones, but they are more expensive and I think the difference is negligible. I'm not gonna have the "true" vintage 1073
