Reasonably-Priced Linear Power Supply for WIMM Pro Plus Streamer

@ted_b

Yes, I have extolled the virtues of these R-core power supplies here before (I have 3 of them, all 50W versions here, so a few more dollars (maybe $20-$25) than the one you linked to. Overkill for a Wiim Pro + or a Fiio K11 R2R which is what I'm using 2 of them on? Perhaps, but the proof is in the listening. 

They are grossly superior in terms of build quality and sound quality to something like the LHY LPS15VA, which is a toy by comparison. Yes, that will give you some improvement in sound quality but nothing like the LPS that Gabster tested and you linked to and I also own. 

You will not regret going overkill on a power supply like this and, as you say, it does not need to be a costly exercise. 

Good quality power cords are also important here (Preffair 503 with copper connectors on Aliexpress is outstanding) as well as a quality DC cable from the LPS to the DAC or streamer. $25-$35 will get you a very good silver plated copper or even all silver DC cable (USB C to fit the Wiim if you like) from someone like KAM Audio in HK that will also be a marked improvement over the giveaways that generally come with these power supplies. 

So pretty easy to come in with something very, very good all in for around $200 U.S. 

The immediately apparent difference between linear and switching power supplies is the absence of background noise. Any of the aforementioned Aliexpress units that cost roughly $50 delivered will do that.

Tales of power supply-related sonic improvements above and beyond noise suppression are... another matter, let's say. In any event, it should be obvious to everyone that spending $500 on a teddy prado or sbooster supply for a $200 wiim makes no sense. But spending $50 does, and will result in a noticeable improvement.

i can attest to that...

Linear tube Audio without a 2nd thought  build quality

And sonics best under $1200 $750!a bargain

I tried one linear power supply from Linear  tube audio...

Nothing cheap could compare... Dead silent noise floor level i even remember it after 2 years now...

My system value being 1000 bucks it made no sense to buy one though...

i have tried one with their microzotl tube amplifier  which could not beat my Sansui alpha for a very demanding headphone on many front (  K340)... Then i returned it...

It is the best linear power supply i ever tried, linear Tube audio service is flawless ... I am no expert in power supply  for sure ...  But a noise floor level  almost zero noise you dont forget it...You hear it...
