I would suggest the Tara Labs RSC Reference Generation 2 although that may top the $200 a bit, like $215-220 I think. Or if you want to stay strictly under $200, then the AudioQuest Viper at $195 (1M). Both of those are close in performance - neutral, revealing, good tight bass on the low end. I auditioned both recently and went with the Tara Labs. If you go used, then you can maybe even find the next step up for both, the Tara Labs Master Gen 2 I have seen used for $195, or the AudioQuest Python should be in the $200 range used.
