Breaks easily and too bulky, would not recommend it

I've been using this to power my NS-10s. The unit itself is super bulky and heavy, which has been a hassle whenever I needed to transport it. I've also had to get it repaired more than twice now because it stopped working properly (I would lose sound on either one or both speakers).
