I bought this alongside the new 5C mix cubes, and I'm pretty happy with the result - it does what it says on the tin. I tried the 5C's with a Pioneer A-400 and they didn't seem anywhere near as punchy or precise in the transients. This did feel a little pricey for such a small amp and considering the nature of the 5C's, but I took a leap of faith and don't regret it. Seems like a happy medium to go with the manufacturers recommendation rather than spending a fortune on something that might not make a lot of sense for this kind of monitor, or getting something cheap that isn't as 'true' sounding. Sits nicely in the rack, but then the power switch is impossible to get to, which is a bit annoying if you want to turn off when in use.
