AliExpress. I don't think he's going to help me in any way.

You don't have clipping when listening to a piece of music on the word "trouble" ?
No clipping. Just tested.

OK, Macbook should be free of distortion.
Have you though tried to set the right default devices in both system settings /sound as well as audio-midi-setup?

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 unbalanced out measured by L7audio for the W2

That is impressive indeed.

Hi folks,

I was fallowing this thread when it was only 20 pages long and you got so far ahead...Now when the hype is gone a bit can someone give me an update if L&P W2 has EMI noise using it with iphone ? Most importantly how does it compares to dongle king S1 ?
Cannot comment about iPhone induced EMI noise as I am an Android kinda guy, but I have not experienced any EMI with my W2 and LG v30. With the LG v30 and S1 I experienced quite a bit of EMI noise.

I do like both of these dongles, and appreciate that the S1 supports MQA (I have my asbestos suit on, folks, so don’t bother roasting me!). But the S1 makes portable use less appealing and I find I am using the W2 more.

I only get EMI when I try to use the OTG adapter that places the W2 on the back of the phone like pictured below. When I use the stock cable, I never have EMI issues.

Well, since the picture "above" is from my setup (good-old Galaxy S9, Android 10, mostly streaming Amazon Music HD, and using UAG hybrid metal/plastic/leather case) with W2 and that 180deg usb adapter from ali while streaming - zero EMI interface. And I often have it on my desk while working at home right next to my laptop and some other DAPs, and still never experienced any EMI interference.

Yeah, I needed to borrow that for illustrative purposes :wink: It could possibly be that I have a defective unit if you're not getting the same interference or noise I get from that otg cable.

You mean that 180deg otg adapter? That is one possibility, but another, what case are you using on your phone? The case of the phone itself is another layer to either provide better isolation or the opposite - a path to pick up more interference. Plus, the phone model itself can make a difference, depending on where they place antennas and how close they are to the body of W1/W2.

Yes, the 180 degree otg cable was what I was referencing and I use the LG V60 phone with a Ghostek silicone case.
