Fosi LC30 amp/speaker switcher experience?


Ran across the Fosi Audio LC30 Selector for amplifiers and speakers. For about $130 it sounds like a great way to AB speakers or components to compare performance at the flip of a switch rather than unplugging and reconnecting audio/speaker cables. However, wouldn't it be adding another component to the audio stream, potentially impacting the comparison? Does anybody have any experience with the LC30 and its impact on the audio signal?

My concern would be with disconnecting and reconnecting speakers hot, when power amplifier is running, potentially with signal passing. 

So you would want to see the switches break (the previous connection) before make (-ing the new connection)? Would that satisfy your concerns?
