kind of. granted, the HSK are out of his price range. The Hertz ESK-165 are in the $200 range. But side-by-side, I think the HAT Imagine are better than the Hertz ESK-165. (i know i've been saying that a lot lately, i'm not pushing HAT product, I just think that they are a better product).
The type of music shouldn't influence the type of speaker, but the listening habits do. People assume if you listen to rap music, you don't want SQ, and you listen to distorted music from too much volume and too much bass. Which isn't fair. Rap music on an SQ system can be quite enjoyable - when you hear all of the detailed background riffs and samples the artists and producer put in there. The key, I think, is to run a sub when you mostly listen to rap - so you take the strain off your speakers. Same with electronic music, and anything else with synthesized bass lines and tones.
I don't like the tweeters on the ESK and HSK. I think they are way to bright and harsh, even when driven cleanly from an Audison LRx amp. If you like bright tweeters, you may really like the ESK.
