Perfect if you have a keyboard/sampler set-up that requires several DIs as it's compact and rack-mountable. It isn't a cure-all for ground loops and faulty wiring but providing everything else is working OK, the Palmer does the job. Note, it comes with a hard-wired euro plug so you'll need an adaptor for UK supplies.
I use the Palmer PAN 03 mostly for synths. It is a very convenient way of accessing my mixers inputs, as the unit is rack located near my synth outputs. I much prefer the sound of DI'd synth as it seems to make the sound more vibrant. The input jack are smooth to use and the pad and ground lift buttons feel solid and reliable. The over all build of the unit is solid. The only thing I don't like is the having to use an external power supply to power the DI rack, as it does not operate using phantom power from your mixer.
