I would certainly recommend true-sine wave because you need as your AC-DC conversion to be clean and linear and since the power supplies in them are designed with that in mind, it's good practice and ensures a clean sound. This is the reason why you still see more phat transformers as opposed to switchmode power supplies in the AC-DC conversion process.
General rule of thumb is if the power supply in the device is linear, your UPS should be a true-sine wave. And for the record, our massive UPS systems used in the IBC at the Olympics are all true-sine wave as well. You could still use any UPS you like, but the sound and image will reflect just how good the UPS really is.
