I haven't thrown away the originals. The CDs are in boxes on steel shelving in my garage. I can compare them any time I want. But there isn't any point because I already did extensive controlled comparison tests and I determined that AAC 256 VBR is audibly transparent (which to me means no audible difference between lossless and lossy)... Earlier in the thread you conceded that high data rate AAC was indistinguishable from lossless, and I asked you what audible benefit there was in lossless... and you went back to tangents about definitions of words and abstract theories about numbers that were unrelated to audibility. That is what keeps sending us in circles. You never address my question. What is the audible benefit of lossless when lossy sounds exactly the same?
