Test WIIM pro+ with different power supplies

And who says that the ripple noise level is the only thing which matters?

Dear cc_rider,

I know this must be quite hard for you:

You quoted Benchmark, and YES, right now do live with that, what they said: ...."can be....".

Apart from being noisy to the device they are powering, switch modes also saturate the surrounding area with em radiation. Try holding a non-contact voltage tester near one (for testing for live wires in walls). It will start responding in quite a wide area. This is EM radiation that other non connected components will also pick up.

I vouch for an iPhone 5V usb supply. Clean.

I use an apple charger with a 3 pin extension cord for grounding.

I have a 5V linear power supply for my external DAC. There are 2 outputs, so I connected my Wiim Pro to try. At first, I thought I felt more silence and a deeper bass. After 2 days, I reconnected the original power supply and ... I found a dynamic that I had lost. With headphones, it is even more obvious.

I have the same experience

I don't find anything wrong with the kit that the WiiM provides out of the box, it's "good enough" to start using the WiiM and that's better than what you get with a lot of other companies.

What brand and amperage spec. on your LPS ?

 

[Dom56]

What brand and amperage spec. on your LPS ?

Audiophonics 5V - 2.0 A - maxi 3.5 A

 

[amix]

For example?

For example?

I bought a CD player a few years back that came with no cables, not even the power cable.

I ended up returning it since my 80s units were better, but yes disappointed was how I felt when I opened the box.

Amps also famously come with nothing, I bought a Cambridge audio amp that came with a lovely cloth that I'm not sure what it's for, but no RCA cables, no optical cables, and the remote had no batteries out of the box.

WiiM provides a cable for every input the device has.

But also, no batteries.

I don't really use the HDMI input of my WiiM amp, but I sure appreciate having a spare HDMI cable!

I sort of understand why they don't.

Most people who spend more on hifi separates will probably use aftermarket cables with them.

I would never use the very cheap cables that a lot of stuff comes with but typically spend about £10 on something a bit more solid, it's not really about the sound, I just prefer the more robust connection.

Saying that, I'm perfectly happy to use the RCA that came with the Ultra.

Wiim don't supply a coaxial digital cable, so I bought one for about £12.


It's a bit like more expensive bicycles don't come with pedals, as there a few different options and everyone has their personal preference.

I understand it too, however my point was more that you can use the WiiM straight out of the box, even if you've never had an audio system before.

People who are new to the hobby can use the WiiM cables, then try alternatives later, you can't do that if you don't get any to start with.

I had the same result with an Allo Nirvana linear power supply on my Wiim Pro Plus. Dynamics became compressed… I have a Geshelli J3 Dac and it ‘sings’ with a Jade Audio Fiio PL50 linear power supply ordered from Aliexpress…

I just discovered a new device, and there are many, a capacitor filter for DC voltage. I bought this unit on AliExpress, "5V-25V 8A Suitable for Switching Power Supply and Linear Power Supply Sound Card DAC Raspberry Pi Amplifier". Just go to AliExpress, copy and paste, and it will take you to the product. It was $60, I bought three, and they work. I can see using these with something like the ifi $69 power supplies sold on Amazon. I have one in between a $600 Farad Super 3 LPS, and my Volumio Rivo streamer, and the sound improved, more clarity if that was even possible. Not just my ears, but others in the house heard the difference.

Allo Nirvana is a switching mode power supply (SMPS), NOT a linear power supply.
I am using an Allo Shanti supercapasitor linear power supply powering my Wiim Pro. Huge uptick in SQ compared to a SMPS or a cheap LPS.

If you really think that the power supply matter for the analog part of the WiiM, then you should use a powerbank. But I guess that doesn't look as fancy.

For the digital path, the kind of power supply don't matter. Either it works or not.
