What's the cleanest possible way to transfer a standard-IPS four-track cassette master?
I recently picked up a mighty fine Nakamichi DR-1
tape deck to transfer all my old two-track, direct-to-tape cassette masters. I am extremely pleased with the signal/noise ratio and the adjustable azimuth control in particular. What a life-saver!
However, that only accounts for about half my early musical output. The other half was recorded on a Fostex X-28
four-track. (This is the early, standard-speed X-28, not the later, high-speed X-28H.)
I've had a bear of a time finding a used X-28 anyway, but now that I know what miracles I can work with a higher-end machine, I'm wondering if there's any comparable box for transferring old four-track tapes. I am not at all impressed with the signal/noise ratio on the X-28 in playback mode, so I'd like to do the best possible job on this "archival round" before my life's work completely disintegrates on me.
So, I'm wondering if there's an actual machine designed to do this, or if there's an existing high-end cassette four-track which might serve the same purpose.
(I know I can always transfer the four-track tapes one side at a time in the DR-1, and then reverse/align the stereo tracks on Side B, but I don't trust the variability of playback speeds and I don't want each side to drift slowly and painfully out of sync over the course of 30-45 minutes.)
