This plugin is dope. I find it great to put in between my plugins in Reaper. As you know, Reaper puts all of the plugins in a vertical stack and since heat rises you sometimes get some unwanted distortion in the upper plugins. If I put a rack spacer between each of them this issue tends to be minimized.
I do find that the additional airflow provided by the hipster spacer seems to work better than the other spacers. I'm not trying to judge here, just saying, the other spacers help as well but the hipster spacer allows air to flow in from the front of my monitor. Granted the thug spacer has some airflow, but, it's just not quite enough and I'm not convinced that the same care and attention to detail clearly present in the hipster vents was put into those holes in the thug spacer.
Maybe if you do hip hop, the additional heat with just the right amount of flow is just the ticket. Since I mostly do ambient and experimental music that nobody listens to, I prefer the extra air.
