Tae,
The xu208 module does not have the same clocks as the Singxer su1. I’m not sure where you are getting that info from.
And yes to clarify, I have never said that the xmos u8 or xmos xu208 module is better than the Hdmi i2s input. I want to be sure facts are straight and nobody is confused with your posts you have made. I’m very happy for you that you are enjoying your dad along with the xu208 module.
But the short of it, the only thing the Singxer su1 and he holoaudio xu208 usb module share alike is the xmos chip. That’s it!
Singxer su1 has femto crystek clocks, and depending if you have 2018 version or previous version, they are different freq sets of crystek clocks. Also 2018 model now has new 4way circuit (no more lvds) for i2s and improved Hdmi connector. Improved firmware for fpga, improved Spdif, more official support for dacs.
The clocks in the new holoaudio xu208 module are quite good but not the same as in the su1. I need to clarify that as when I read Tae’s post it reads to me that it’s claimed to be the same. I am trying to clarify so no one is confused with that post. Maybe you borrowed an su1 to make these claims, but last we talked you were not interested to try the su1 for some particular reasons you had. And that’s ok, I think the xu208 module was a good small step in the right direction.
Also, the older xmos u8 module was never a bad usb module. People criticized it yet the measurements would show its much better than majority of usb implementations. It’s just that our i2s input has been the best or most desirable especially if you enjoy dsd native.
I’m not sure what extra boxes or cables you may speak of Tae. But if you may be talking about an isolator, then neither our usb module or the su1 have the same isolation that is capable from the box I think you might be referring to.
On a side note, we have been shipping spring dacs with the new xu208 module for a while now. And will update you with when that change happened. But some of you likely already have the module in your dac and not knowing it. But you could tell by seeing what the driver tells you. Whether it’s an xmos u8 or xu208 in the control panel of the Asio driver under info. But I could be wrong, I will double check tonight to verify. And also give some dates on which dacs May have this module installed. If you are using an su1 I personally would stick to what you have. But for some who want a better usb module and are not using an su1 or kte su1 than yes, it’s a good alternative that is a natable improvement compared to the standard xmos u8 module.
Hope this clarifies things. And if I have to edit any of this I will. I am rarely ever to post on Headfi except for when one asks if I quoted something. And I did not say this module is better than i2s.
Thank you to everyone who chooses our products! We are so blessed to have such enthusiastic customers.
Best,
