Win10 drivers or ones it comes with are not good at all. FYI

Windows 10 probably just loads a generic Usb audio class 2 driver, and it doesn't mean that F1 driver will work.

My Windows 10 loaded xCore drivers automatically once I told it to automatically find them. From what I can tell xCore are not generic drivers and are specifically for XMOS products. I believe this is one of the recent updates to Windows 10 Fall Creators update (4022716) that came out in November. It now recognizes USB audio devices and will load drivers if they are available in the Windows library. Apparently the xCore drivers are in the library and probably many others? I know this has always been a problem with Windows but apparently no more with this Fall Creators update for Windows 10? I guess it also has some new headphone spacial effect options?

My breeze sounds really good with these xCore WASAPI drivers.

Hi,
What's your feedback about the Matrix X-SPDIF 2 ? It replaces which DDC ?
I've read that it sounds slightly better than the SU-1.

It sounds good but I have nothing to compare it to, my first DDC, only bought it to feed SPDIF to a vintage DAC which doesn't have USB, hoping to find other uses in the future (IIS). Oh yeah, it is small but I would advice against swimming with it, so heavy you'd drown :).

Hi,
I've a DDC (Breeze DU-U8 modded) with an i2s output, besides RCA/AES/toslink outputs.
I use spdif outputs.
Does i2s sound better or not ?

I tried i2s in the past using another drive (UPNP streamer), but I got no SQ difference between i2s vs spdif, so I'm wondering if it worths another try.
Thanks
Rgds

If you using spdif, Some Dac might need receiver chip to convert spdif signal to i2s signal before feed the signal to Dac chip. Some receiver ICs have high jitter (CS841x series are 200ps or greater), some doesn't (AK411x, DIR9001, WM8805 are about 50ps or less). I'm using Leaf Audio Amanero as usb-to-i2s and ESI-Juli@ for spdif with Weiliang's ES9038. I hear no significant different between spdif and usb-2-i2s

The breeze audio Xmos U8 USB to SPDIF/COAX finally arrived. Have hooked it up to the ifi iOne using coax and iDSD BL using optical. Both outputs working at the same time. Feeding the unit using usb from PC/ MusicBee [WASAPI] For sonic differences, Ihear none so far apart from the placebo in my head but i think the low end could be a bit more pronounced than before. I need more time with this setup. Nifty, tiny little device which is powered by the usb input inputting the audio signal.

Here is a question. I'm using a vintage Parasound D/AC-1000 and it can only do 16-bit and it'll drop any extra LSB it receives right on the floor. Unlike in some earlier XMOS drivers I've seen I can't seem to be able to force my Matrix DDC to 16-bit mode and as it is seen as a 24-bit device in the OS any WASAPI-aware app that doesn't allow explicit output bit-depth selection, e.g. Tidal, is free to decide to dither to full 24-bits from 16 and that can't be good. Am I missing something?

I spoke too soon about the Breeze Audio XMOS U8. It's giving me problems with frequent disconnections. Could someone please help me with a proper driver.
