Thanks hdm for the dc cable upgrade option...I always wondered why up grade PS and power cable to it and leave the flimsy pos dc cable. The cable form Kam Audio sounds/looks like a good option at a good price.
Reasonably-Priced Linear Power Supply for WIMM Pro Plus Streamer
I just received my WIIM Pro Plus streamer for my second system, which is most often played at a low or moderate volume level.. Set up was prompt and simple, using my iPad zero for set-up and operation. It feeds music to my Rega Brio integrated amplifier and Paradigm Premiere 200b bookshelf speakers. The sound is excellent, it I wonder if going from ehat appears to be a phone charger wall wart (USB-C) to a linear power supply would make an improvement in the sound quality and what options there might be, not to exceed the roughly $200 price of the Pro Plus. BTW, although both the Pro Plus and the Brio have internal DACs, I am using a Schiit Modi 3+ DAC in the system. I will do a comparison of the three DACs to see if there is a significant difference in sound quality. If not, I can simplify things by using one of the internal DACs.
