I noticed in the Dec. issue of BBC Magazine an ad for GG recordings on CBC Records of Canada. I have only the recordings by GG on Sony Classical. Some of the recordings are of the same music. I wonder if there is any difference in the quality of the recordings. Has anyone compared for instance a copy of the Goldberg Variations on CBC Records with the Goldberg Variations on Sony Classical? I should probably purchase a GG on CBC to make the comparison. Would I have to get it from Canada, where and how?Fred StubbingsRun virus scan weekly
