I have tried a no brand RCA switch, not the same one as you listed. I bought it for $29 from Target or RS, I forgot. The one I tried was not good, it blurred the sound, makes $1000 DAC sounds like computer sound card, and worse than my mobile phone's output. Returned immediately. You can first try to compare the sound with vs without the RCA switch. If can't spot any difference, then the switch is good enough, go ahead with A/B test.Hope this RS brand switch is good.
