My opinion: The Aurender unit should have adequate power conditioning built in to it to deal with any typical home AC power noise. If it needs an external power conditioner it should come with it or at least specify what is required.
Don’t over power condition!
Recently I bought the Aurender W20SE. Sounded incredible first day, just everything you’d expect from a 22k streamer, jaw dropping. But then I started getting dropping and smearing, sounded like CD skipping. Frustrated I lost the original bliss of the finest sound I’ve ever heard, I began having regrets of dropping the cash on the piece. I worked with the excellent Aurender customer service through their great app, they wanted to download some new software into the W20SE after sending them an audio clip of the dropping and smears that were irregular, maybe one every other song.
But do you know what the actual problem was? Over power conditioning! I had the Puritan PSM 156 hooked into the Audiowise RF Stop, and as soon as I got rid of the RF Stop and plugged it in directly into the Puritan problem solved. One of the wildest lessons I’ve learned thus far in my young HiFi journey, over power conditioning can destroy your sound.
