I think the salesfolk at Woodbridge are a bit biased towards the NAK.
Many quality manufacturers use HX-Pro, generally in their high-end units.
(based on the manufacturer's specs in the Oct '85 issue of Audio magazine).

Having just gone through the job of finding a new tape deck, I checked
just what HX-Pro does (or is supposed to do).  In short, it changes bias
levels depending on the high frequency content of the program material.
This is supposed to overcome at least some of the deficiences of the tape.

If HX-Pro is a subterfuge, then don't bother getting noise reduction
either, since the noise in a tape is obviously because of the heads only,
and never the tape. (:-)) I'm not sure what kind of distortion HX-Pro
introduces, if any, but the MEASURABLE distortion on HX-Pro equipment seem
to be as low as on any other deck.
