Hi Dan,
What tape would you use to record live sound with good archiving properties? US Recording Media seem to suggest that for the live sound SM900 is the best: "recording live material, we strongly suggest SM900 for the increased dynamic range, headroom, and lowest noise characteristics. SM900 tends to be the most transparent tape with an amazing sound field."
At the same time they do not speak of 468 that highly: "RMGI 468 is designed for more non critical applications, but still has a large following for its sound." I would think the Tape Project is critical enough :-)
You mentioned that 468 is excellent for archiving at the levels you use. Archiving is definitely important. What levels do you use in the TP?
