Weiliang/BRZHiFi Linear USB power supply questions

Hi very interesting and thank you
Have you carried out any specific download speed tests using the linear PS ?
Managed to do a simple A/B between the stock SMPS (1st 3 pics) and the BRZHIFI 12V LPS (next 3 pics).

Each set of 3 tests was run back to back from same location. Quite big variations between each test run. Not sure if this is normal or if the diagnostic app is accurate. I’m using Deco TP-Link mesh system and app diagnostics.

Looks like the stock SMPS gives better upload speed. Download speed looks to be about the same.

Hi thank you for the very kind and valuable testing
On the basis of your results I think I will stick with a smps
I have already swapped the stock one on my modem/router for an Apple smps I had at hand mainly because I have great respect for the brand products in terms of reliability and overall quality
It doesn't heat up much even if left on 24/7
For sure smps are very convenient
Thanks a lot again

How’s your experience so far? I bought a bunch of 5V and 12V LPS from BRZHIFI as well. Very well built And reasonably priced.

I’m not very electrical savvy. So I just play it safe and ensure the voltage and max amperes match the DACs, streamers and routers I’ve plugged them to.

So far so good. After a few weeks of use. My wifi looks to have improved Sound quality improvement could be placebo effect I’ll concede.

I hope some experts here can test BRZHIFI LPS unit and even vs some of the other well known brands that cost way more.
I would say definitely placebo effect... Adding a linear PSU to a piece of networking equipment is going to achieve nothing except probably wasting a few watts compared with the stock switchmode supply.
