Re 32kHz capture without decoding or resampling - if you don't want to invest in a DDS drive and SCSI-FireWire bridgeboard to do the transfer via standard data buses and software, which is the best way to transfer DATs, there are a few legacy capture devices that support 32kHz that won't break the bank like e.g. the RME device you mentioned would. The optical input on Power Mac G5 towers can, for example, if you have one of those lying around. The Edirol/Roland UA-1EX from the early 2000s can also do this, and works through OS X 10.9, and on Windows 10 (though there is a specific way to get the drivers to work on that OS). I picked up a couple of them on eBay, gifted one of them to my former employer, and kept the other one. They went for between $20-50 US at the time and I wouldn't spend more than that. Checking, there aren't any up now, but they could show up. There are other models of this make from that era that might also work with 32kHz input, but I haven't personally tested this.
I had a couple of threads on this last year about this very question with much more detail (or at least more conversation?) first here:
With an update here:
I don't think I mentioned the UA-1EX in those threads as a possible capture device, though I did rule out a few others (the Mac Mini mini-TOSLINK input, the M-Audio FireWire Solo, and el-cheapo USB devices based on the CM6206 chipset).
Note that when capturing a mixed frequency tape, your capture software may crash on frequency switches. This is what happens e.g. with Audacity. Nice thing is that Audacity reopens straight away with everything lost, at which point you may save and export.
