Not to argue Jon, but I find the QSI Q3 Emulator comparable to the LokSound in both running characteristics and sound sets. It may require some CV adjustment to achieve perfection, but I've handled that with ease.
My only concern with QSI is the time it will take QS Industries to get up to speed replacing QSI Solutions for customer service.
I also own several units with LokSound. They are stellar performers, and I will use more of them.
