The EP350 and EP500 have a lot of differences. They look the same because they share the same cabinet but the EP500 has almost double the amp power, a longer x-max woofer, and a way more sophisticated control of the frequency response and max output limiting. This means it plays a lot louder, a lot lower, and never gives you a hint of straining. I think you would find it a nice upgrade.
