Have you heard both?
I haven't personally heard it, but I have friends with them who also have the W2. Also, you can compare their measurements on audiosciencereview

Looking for a little help. I’m trying to connect the spdif out of the W2 to the coax in of the FiiO BTA30. I have a cable from my dx300, but it doesn’t seem to work for the W2. It works with the dx300. So, is it a ring issue on the 3.5mm plug? What cable do I need?

Thanks!

Here is the iBasso one:

It's not gonna work because iBasso daps have a dedicated SPDIF coax output, not combined with phone output, thus they are using 2pole cable you have in your picture. W2 combines coax and phone outputs, 2pole not gonna work; the cable I'm using is 4pole and it works OK.

Great, thank you.

Was hoping I didn’t need a new cable. It’s never-ending with this darn hobby!

Got this cable long time ago, don't even think the company is around anymore. I just did a quick search on amazon under "coax to 3.5mm 4pole audio cable" and see a few results like this one which should work. If you have original R6 or R6 Pro daps, they come with a similar coax to 4pole 3.5mm cable. And the amazon listing link also mentions in comments that someone used it successfully with R6 dap where you have LO/Coax combined, thus need to use 4pole 3.5mm plug.

Just to add more info, is It has less to do with how many poles there are but how it was internally wired. It would seem L&P is using the FiiO standard (TRRS -> Left/right/ground/SPDIF) but even FiiO has used different standard in the past for its hybrid 3.5mm+SPDIF output. There is no common standard that every manufacturer follows, so you can't assume every cable will work though FiiO standard is probably the most popular as it is the easiest to implemented.

Yes, exactly! I mentioned 2pole vs 4pole since it is visually easy to ID, and former one is used with dedicated coax ports vs the latter one with multi-function ports thus more wiring contacts. But then, I also saw a few listings with SPDIF coax to 3pole 3.5mm which could confuse people, though one actually mentioned that only 2 rings were connected (assuming GND and SPDIF).

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