Yes, I have had very similiar problems in debating if some of TSP's releases are lossy or lossless. You have to keep in mind that since TSP is a silver CD selling comapany (or at least used to be), they are known to process their released material. This processing may also include the deadly noise reduction which can lead to some trouble, like I said in my prior post, when observing the FA and SA of a wave form and determining source origin.

At first glance, this doesn't look like FM either. It sounds it, but doesn't look it, because I don't see the usual spike at 15k.
