DC cable here:

I only paid about half of that price for the DC cable though! So you might have to watch for a sale price on that one or something similar. 

I am also considering buying one of the wiim devices to use as a streamer to connect to my Grimm MU2. While I will be using Roon/Tidal to connect to the MU2 directly, I wanted something my family could use to connect easily (AirPlay, Chromecast). An interesting point to note is that the Wiim Ultra doesn’t support AirPlay, AFAIK.

I think to spend almost as much or slightly more on a decent LPS, power cord and DC cable as the streamer itself but I've found it to be very worthwhile. YMMV, just basking in the mediocrity here. 

“Basking in the mediocrity” 😂

I suppose I belong to the mediocrity basking club too. I sold all my external DACs after comparing them to the WiiM Ultra’s. Some of those DACs retailed for many times the Ultra’s price. 
 

Anyhow, there is no way to bypass the onboard power supplies in the WiiM devices without opening up the units. Not sure how an LPS improves streaming, especially when an external DAC is involved. Seems much more likely it’s a placebo effect. 

I am using the linked power supply from Aliexpress, which is a very high value item IMO, along with a Preffair D503 power cable with all copper male & iec connectors  and a silver DC cable (you will want a GX 16 2 Pin, Pin 1+, Pin 2- to USB C connector on that for the Wiim-I went with an all silver cable for that), both also from Aliexpress.

So how on earth is this bypassing the internal SMPS? 😂
