I've gone so far as to record the tapes straight into flac and listen to those on my ipod instead.
I know every warble, wow, and flutter from those old tapes, I even have a rough chronology in my mind of when the tapes developed their defects. The too hot car stereo in my friends camero that summer day... that lousy walkman that tried to eat it.
I can play the modern digital copies in the right order till the cows come home and be unmoved but even a whisper of the noise between tracks on one of those old tapes and its '94 again and I'm back on the beach at sunset with that girl in my arms...
