I absolutely LOVE the Nordstrand Pickup. As Rich said, Hifi is quite a good way of describing it, yes. Just really crisp and the clarity is awesome It really helped bring my G string back from the dead (couldn't hear it live whatsoever!) If you are going for one in your 5 string, make sure it's the 5.3, as then it has the proper switching options, the 5.2 in mine has a really dubby sound in the middle position as it couldn't be wired up properly without the additional dummy coil in the 5.3. It makes for a really cool sound though so I never bothered changing it out!
And thanks Nick for the comment on my fashion sense...Haha...
