It reminds me of the Apogee EQ reviews.
I think it's important to figure out how we enjoy Audio. Some do so by endlessly buying and tinkering. Some by falling asleep to Chopin. There's nothing wrong with all of it.
In general though, I think that adding an EQ should be done with purpose, if not measurements in mind. I don't know if this brand of EQ would degrade your experience or not, but I do think that EQ's are best implemented with at least some idea of a goal. If you just want to have it to play with it, get it! :) Or consider a miniDSP as a cheap playground.
