    The S/PDIF cable took 13 days to get here and it works with no problems. I have not done extensive testing but it looks well build, does the job, and it comes at an attractive price.

    Thanks for all the suggestions. Given there is no guarantee and returns are a hassle, I give this budget option a try.

    Cool thank you. So they state THD+N@1kHz@-.5dbFS BW 22-22kHz .00014%, SINAD 117db typical for 24b/44.1kHz@no-load on an unbalanced out vs. the THD+N@1Khz 0dbFS 10Hz-20kHz 0.000116% -119db on balanced out measured by L7audio for the W2. THD+N@1Khz 0dbFS 10Hz-20kHz 0.000303% -110db on...

    Most people seem to agree Mobile Market share by OS :beyersmile: However, the 22% of users who can afford an Iphone probably also represent a good share of the people who could spend $299 on a dongle.

    I wonder whether L&P could explain in technical terms what the difference is between the Tune choices of 01 and 02. Is there a passthrough mode?

    Okay, here are the findings. It is a bad news/bad news result for the Iphone 12 Pro Max and good news/good news for the S20 Ultra. With the Iphone the voltage provided to the W2 is a low 3.76V at 0.24A and Volume at 93 is the last setting at which it is stable for me with the HE1000se (32 Ohm...

    I managed to get hold of my wife's IPhone again but then I realized my USB power meter only has male input connectors, so I need a USB-C female-female coupler to connect the L&P lightening cable. I will order that piece and report back.

    If I am not mistaken then the HE1000se has an impedance of 35 Ohms. I did my test on the balanced output? I will repeat the experiment with a USB power meter in the chain. Then I can try the W2 direct ly connected to the IPhone or with a power bank/hub in the middle to see whether that makes...

    You are connecting the W2 to an IPhone and when you raise the volume on the W2 over 85 it starts distorting due to lack of power via the USB port? Which IPhone model and what headphones are you using? I just tried this with my wife's IPhone 12 Pro Max and an HE1000se. I don't have Neutron on...
