Saw a video on this thing.

It's a simple and neat idea (one of those 'why didn't I think of that').
Using the Octogam hammond enclosure is a really good idea too.
This would be easy to DIY (it's all passive), but for the cost (inc. cables) is not a bad deal IMO.
A friend of mine picked one of those up to use with some synth stuff. Really nice idea, and it's a great design. It was also not expensive at all. Didn't get a chance to play with it though.
Just to save time googlin'
