Cheeg: Gkelly answered your question to me about ethernet connection above: the Wiim will automatically recognize your streaming platform when connected to Ethernet.
I use a Pro Plus with an outboard DAC with this power supply (50W/5V/3.5A) and a good power cord and DC cable and this power supply is probably the equivalent or better than most of the supplies that you’d find in $2K-$4K streamers and performance is outstanding. Plus it’s a simple connection with the Pro or Pro Plus vs a major modification to do the power supply on an Ultra.
I just plugged a Zerozone 30W/2.5A LPS into my Pro Plus a few minutes ago as a friend just bought one and loaned it to me. Also Rcore, but a bit more expensive with possibly better filtering, but only 30W and 2.5A. Will be interesting to see if I can hear any difference between those two supplies. The Sengterbelle is definitely far superior to the less expensive 15W Talema transformer based supplies on Aliexpress for just a bit more money.
This is an interesting read when it comes to adding a better power supply to the Wiim’s (albeit the lowly Wiim Mini lol!) and comparing it/them to some more expensive fare.

Rest of my system is Unison Research Triode 25 with Opera Grand Mezza Speakers & Vera-Fi Caldera 12 Subwoofer. Analog is Michell Gyrodec with a couple of Jelco tonearms & Audio Technica Art 9XA and modified AT 33 Mono with an Aqvox Phono preamp. So remotely acceptable stuff capable of showing off improvements in different parts of the audio chain.
