The new hybrid from Whizzer might be an interesting contender too, not to speak about the, so far quite elusive, Simgot hybrids.

As for the Secret Garden, I take it from recent posts that it's more v-shaped than the King Pro which I think rules it out for me.
Maybe it's more U shaped than V? Nabillion_786 brought up a good point about this. The male vocals wouldn't be so forward if it didn't have some decent mids. It just has some high peaks and lows. I guess you'd have to try it. I know there are some others here with SGs. They recommended it to me lol! My some more prospective would help those on the fence about the Secret Gardens. Hopefully, they chime in sometime soon. Btw, the Whizzer looks pretty cool. Seems like a good deal for a Knowles BA set. From my experience, they really live up to their name.
