I'm sorry, but it seems that I couldn't find specific information about the FTS-300 Power Amplifier in my current search results. However, I can suggest some great alternatives! For instance, you might consider the FTS-6000 MK3 Professional Power Amplifier, which is available for R6200, or the FTS-9000 MK3 for R7800. Both offer high-quality performance for your audio needs. If you're looking for something more affordable, the High Quality 800W 2 Channel Wireless MINI Hifi Power Amplifier is available for R548. Let me know how else I can assist you!
