The popping noise play/pause may be down to the cable you use. The included one is not of high quality get a better if you can.Just got my W4 and love it, but had a couple of questions.
Does anyone notice a popping noise when pressing play/pause with Tidal? It's not a big deal but a little annoying.
Also I noticed there's a NOS filter. Is this a delta sigma DAC? A bit confused since NOS is usually an R2R thing.
And finally, is it worth updating firmware? Any new features?
Thanks
This is a sigma delta dac indeed, and the NOS filter is to give you a closer sound to a 2r2 dac. Updating the firmware it's a must imwill say. Very easy to do and latest firmware bring other iem profiles such as IE900 and the ability to play/decode native DSD512. And the changes are on the first page.
