Better than cassette? Ya sure, but then that's not hard. "Just below DAT?" no, not so much. With Hi-Fi enhancements yes it could get about 70dB SNR (CD and DAT are 96dB) on a new, unused tape. As with all analogue, it degraded over time and suffered generation loss.

I'm not sure about actual quality, but at least there is an important technical difference between regular and Hifi audio on VHS. One uses a portion of the tape in the same way as audio cassettes, the other encodes audio into the video storage area, where there is more bandwidth.

Incidentally, some early digital audio systems used videotape as their storage medium, again because of the high bandwidth. An encoder/decoder was used along with a regular VCR. DAT uses a similar mechanism with rotating heads to achieve the necessary bandwidth.

Of course there is. This is just something from a personal experience, something that has made life interesting again. I also think that FPGA design has improved my understanding of programming, for example because it forces you to think about parallelism much more. The low-level aspects of doing more with less logic are also intriguing.
