For me, I just want a streamer with USB out, dont care that much about the DAC section, since I use my own DAC. If that is the only difference from the Wiim Pro Plus, its not worth a whole lot more over the Wiim Pro plus, and even the lowest price point $349 is too high. I am assuming they will...

I just received a much better/more expensive FNSRI FNB58 USB tester and everything now makes sense. A dumb power supply shows no protocol with D+ lines at 1.8V, using the same supply with a cable with D+ and D- shorted reports as a DCP1.5A, like it should. The stock Wiim supply shows the same...

"I can promise you that Wiim devices do NOT run on the 5v USB supply!" can you enlighten me how the Wiim Pro /Plus utilizes the 5V USB power to drive the digitial board? I noticed the audio board has two 4700µF caps. Thanks

What your measurements suggest/mean is that if one is using the Wiim Pro or Plus as a digital streamer only, a high quality linear supply should make no difference vs the stock SMPS. If so, I should stop trying to improve my Wiim Pro Plus with a better power supply! Thanks!

Very impressed by your measurements. Have you compared the bit perfect digital output via coax and toslink using the stock PSU? You indicated that you used a very high quality PS for your measurements. Just curious if the power supply would make a difference for the digital board.

This is a very nice talk by Rob Watts. Thanks for posting. I particularly liked his comment about noise being deliberately injected to make a cable sound better, or more detailed and listening fatigue being an arbiter of that. I completely agree. I have listened to many components that sound...

I have never seen a commercial device (non-DIY) that uses a USB port with 2 wires only and does not negotiate any protocols. That is why I am confused, I did not know these existed. These certainly do not follow the USB-IF standards.

Here is the logic (which could be faulty) - I attached a PD power supply and it connected up as a AAPL 2.4A, 5V supply. How would it know to put out 5V if it wasnt polled to do so? My conclusion was that the Wiim Pro was polling the capability. That was the logic. That said, there was a sure...

According to the USB protocols, if there is no D wires the protocol defaults to 5V .5A. There is no protocol under USB where it acts as a simple 2 wire barrel port. That was the whole point of my exercise, to determine if the Wiim negotiated under USB protocols the voltage and current it...

I never get DCP1.5 except at the beginning before reverting to Samsung.

This makes me confused because if one connects the stock charger with the stock cable to the Wiim Pro, then according to what you say, there are no D wires and therefore it defaults to 5V .5A connected to the Wiim Pro. Why would Wiim have a 1.5A charger but only have it communicated to the Wiim...

Thank you. I got a cheap tester RD TC64 and for all the dumb type supplies it read Samsung, whatever that means. With an appl charger it read Apple 2.4A and with my custom cable where D cables shorted it read QC2.0. I have on order a Finsri tester, which is supposed to be much better.. When I...

Are u sure? I compared several and the D pins are open. I think that is the common situation. How did you determine this? Would be very interested to see if I missed something. I have several barrel to USB adapters and the Dpins are all open. I had to make a custom cable to short the D pins.

Can you point me to documentation that states that? So far all the documentation I have read about USB C protocols with D+ and D- unwired state that 5V .5A is default.

I'll try to simplify. Many people are trying linear power supplies instead of the provided noisy switch mode power supply. But linear power supplies are dumb, whereas Wiim uses a USB C power connector. A USB C power connector negotiates with the power supply the voltage and current available...

One issue I could not find any info online was whether the USB C power input negotiated with the power supply the capability of the supply. I was wondering why the Wiim Pro used USB C for power instead of a typical dumb barrel connector. So I did some tests. First I connected my Apple 12W USB A...

Jumping into this thread after reading most of this and associated threads. I have a Wiim Pro plus and wanted a reasonably priced decent power supply better than the stock switching supply. First, after reading some measurements of switching supplies, I powered it with a true Apple ipad 12W...

I see the issue, which was hard to understand at first. For macs, there are 2 versions of wiim home, a native mac os version, currently at 0.1.5 beta and an IOS version 2.7.4. M1/M2 macs can run either version whereas intel macs can only run the native mac version. But the versions have...

I just got the Wiim Pro plus today and setting up was rather straightforward but playing music on my mac is not. I installed the mac OS app on my M1 mac v2.7.4 by downloading wiim home from the apple app store. When I hit "Browse" and choose "My Music" there is nothing shown for my music files...
