I have the vanatoo transparent 0s with a subwoofer. Great sound. They're bit pricey ($600 CAD) but great for desk use as they're small. The additional subwoofer wasn't really needed.

My unit's amp stopped working properly after a few years and after some emails and troubleshooting they shipped me a replacement amp for free, so that was nice of them. I heard the newer vanatoo models are even better too so I'd check those out.
