Any copyright lawyers lurking?

This is a question regarding the personal recording of vinyl to digital. I believe it was tested in the courts and upheld whereby an individual could record vinyl (at the time to tape). What is the consensus on the legality to record vinyl to digital. Ok, that question is likely a simple yes, it is ok. Here's the real question I'm getting to: let's say I record a perfect vinyl album (some of these could include super high quality 45 rpm remasters) to DSD at the highest quality possible, may I share it legally with a friend whom I am absolutely certain owns a legal copy (whether CD or Vinyl) of the material?

Thanks in advance for the discussion.
