i have that IC, yet i doubt if going from usb to coax is the best solution. they are two different things afaik (which isn’t much btw)
No. The coax output is on a spare connection in the usb socket and will only work with that Hiby adapter. It's not USB.

can i assume then this will apply to m300 as well which only has a 3.5 out ?

in other words is every 3.5 out at the same time a coax ?

lastly, any coax to coax cable recommendations ? (as an alternative to hiby usbc>coax)
No, that's a rare feature offering digital out other than USB and therefore only in selected models like all new Ibassos.
If you ask the veterans they might tell you getting custom made silver ICs 😉
I ve got this one for example

i struggle finding a source for my H2.

i hated 2go due to its connectivity bugs.

my use case is portability around the house, so i went on to stack it with a tiny DAP (hiby m300) using an audiophile grade 90ohm usb cable.

hoewever, reading back on the RF noise that keeps popping up here and there, it makes me question how much of what i’m hearing is noise. and yes, it is kind of on the bright side which can cause me some fatigue.

looking into sources that have optical outs, and i see myself way too limited with some older sources, not to mention limitations of optical connection.

besides being prone to rf noise, i don’t like (as @Rob Watts said) that “better” usb cables modulate noise to give you a false sensation of more detail.

so as much as i like my H2, i really struggle to make it right. and that makes me look into daps instead…
Perhaps this small DDC is worth looking at:

Use it with a USB C source, phone etc.

That could be a cheap and simple solution to pc noise. Awesome link

Is the USB white noise issue still apparent with nowadays latest Roon / HQPLAYER?
After finding out that my Eversolo is limiting the max sample rate even over USB I put my Mac Mini M1 Roon Core / HQPLAYER server next to Hugo2 and connected via Cinnemon Micro USB cable.
Absolutely stable without any noise issues plus full bit rate support.
Noticeable tweaking through the filters, currently enjoying Precise Minimum Phase Filter and full upsampling

Any idea about how much could it be to repair a faulty volume wheel?

That Hiby USB-C to 3.5mm coax cable (or maybe this standard) sounds terrible. I have the TempoTec V3D to test. TempoTec V3D's coax-via-USB sounds identical to Hiby R3II's coax-via-USB, but both sound vastly inferior to TempoTec V3D's coax-via-3.5mm. There is an unusual congestion/muddiness in the lower-mids that is very apparent.

I use my H2 with a dx320 via coax and it works brilliantly. Best of all, you can use PEQ settings in neutron player and these are retained even though the H2 is providing the conversion. I usually then link to a tube amp and my hd800 and it sounds pretty end game, at least for me.

First post on this thread so Hi to all........Just upgraded from mojo2 to hugo2 and need to ask you good folk for a recommendation on a lightning to micro usb lead. Needs to be short, about 100/120mm ish ultra reliable and available in the uk. Any help much appreciated.......Thank You.........

I got one in my drawer at work, I don't use an eye phone but it came with it. I'll take a photo for you

Ddhifi might do a micro usb

It will not be a tidy solution, but if you wish to avoid the occasional burst of white noise while playing content, I would suggest you take pains to obtain one of the official Apple CCK.
This is an adapter that communicates with the iPhone for trouble free operation with other devices.
There are two flavours, one is lightning to USB, and the other is lightning to USB with an additional lightning charge socket to supply charge to the phone while simultaneously playing to the external device.
You'll also need a USB A to microUSB interconnect.
