Query: Great Amplifier Switch

This amplifier switch enables multiplexing of two amplifiers to a single pair of speakers, and I suppose that it could be connected as well to switch one amplifier to two pairs of speakers. I have opened the enclosure to verify that it consists of merely a four-pole double-throw switch on a circuit board. Given the simplicity of the contained switch and circuit board, this device appears to be over priced. However, it would not be possible to build such a device oneself at much lower cost, and the end result would not be as compact and nicely finished. A minor complaint is that this device accepts up to 14-gauge wire, but not 12-gauge wire, which is why I rated it 4 stars instead of 5. In reality, however, this amplifier switch does what it claims to do, and does it well.
