Class D is entirely the wrong topology for mid/high range frequency reproduction. I know you can make it work, but there are other topologies that are essentially guaranteed to provide a higher quality experience and the efficiency sacrifice isn't a huge deal when you are working in this frequency range. For LFE playback (I.e. subwoofers), absolutely. Use it aggressively. I prefer class G/H topology for my LFE though. I run class AB for my mids & highs.
