Haven't gone there yet. I own a JB-3, but not a DVD burner, so I sit here and burn 16/44.1 wav then transfer to flac on CD-R from all my DAT masters. Then I store them in a metal filing cabinet and don't ever plan to get rid of them.
Then there's the over 1,000 cassette masters.........................still have them too! Only have about 100 of them converted so far! Of course my wife wonders why I have to keep them all.
