XMOS XU208 USB BRIDGES - THE LATEST GEN HAS ARRIVED!
Mar 26, 2018 at 9:25 AM Post #3,826 of 3,865
I'm using the original breeze duu8, not sure if my drivers will work with your new breeze....
I have the breeze U8 which is the older version of the U208

Here are my thoughts on these units....

Singer SU-01:
XU208 XMOS
Considered great unit.

FUN1:
XU208 XMOS USB
XU208 is the second generation XMOS chip memory is 2 time ofU8.
computing speed arrived1000MIPS,
(U8 is 500MIPS.)
Considered to have not as good clocks as SU-1 unit.

2017 Breeze Audio DU-U8:
2017 have Better clocks?

Original Using XMOS-U8 core workingin500MHz..

Since 1st, November 2017,
XMOS master chip has been upgraded to the second generation U208,
and the installation of EMI power filter, the details better and more pure...

DXIO Pro3Z:
The XU216-512 XMOS is used in this pcb...
It is a XU216 at 2000MIPS and it contains two tile..(!)
It is equal to two XU208 combined in one silicon chip..
One dedicated tile is used for the USB data and the other tile is dedicated to process the audio data to the DAC.

XU216-512 includes 4x more ram than xu208-128 (!),
And 8x more ram than U8/U6.

This is a great unit,
But only a USB to SPDIF unit.

IMO...
All these units are already old and need upgrading.
Its been over a year and half already when F-1 unit came out.
They should all be implementing XU216-512 or whatever else newer out.

I am currently using the Pro3Z with a Uptone Audio ISORegen feeding it power thru USB,
as I found that was better than using it's optional power input with my ifi PSU,
as it is then using the XU216-512 isolation to it's full potentiaI.

I do not know if this spdiff route is equal or better or worse than AES, or HDMI, both which are generally regarded best way to go,
but this spdif certainly way better than any USB.

I have bought a Xu208 card for my new DAC.
I have installed the drivers but it isn't accepting DSD with ASIO support. While that DAC is capable.

This one:

With the TUSb audio drivers everything works fine. But it's an evaluation version.
What's the catch? Those chinese boards won't pay a license fee to get it properly working.?

V.3.4.3 on driver deliverd with card TUSb audio is 4.11.

So youve compared the PRO3z to the Su-01 and proffered the Pro3Z?
what PSU do you use with the Pro3z. ill order the pro3z and would really like to know the LPSU you use!
thanks max!

No i did not.
Only on paper comparison.

The reason to get the su-1 is to use the other outputs.

I am currently only using Spdif thru coax.

I use an ifi PSU into the Regen, into the Pro3Z then out to coax input.

Many prefer going AES with the SU-01 unit,
but for Spdif, not many have tried the pro3z over the F-1.
I have not owned the SU unit,
But I have owned the F-1 and did notice Improvement with the latest pro3Z(not pro3a).

Has anyone used this ? 768k

Plan to upgrade R2R7 Amanero. Pins outs are correct, do I need different software too ? LPSU on the R2R7

I always laugh when I go to the DIYinHK website - these guys don't even know how to read a log scale!

http://www.diyinhk.com/shop/audio-kits/107-xmos-dsd-dxd-768khz-high-quality-usb-to-i2sdsd-pcb.html
They post this quote and the chart below:




As you can see the jagged blue line (Crystek CCHD-975) drops below the solid red line (NDK SD) at 2.5kHz not 25kHz!
Are these guys morons?

Everything these guys claim I take with a very small grain of salt (like ultra low noise regulators).

Wow, thanks for this post. Kinda late that I bought this Xmos and is shipped out already. I was reading into the isolated version, so I couldn’t see the chart comparisons....so, I hope this is still better than Amanero 384

Hi Maxx,

Deciding between the usd216 pro3z and usd379 matrix spdif which is quite a bit id difference in $.

I just need usb-spdif from my car android head unit to play dsd to my car dated but excellent alpine pxa-900 processor with BB 1704-k dac.

I have the hifime U1 (no dac) and smsl x-usb and the pro3z is clearly better with more details, extension etc. aka much less veiled and I am sold on getting best usb-spdif bridge.

Speculation is fine as I dun find any direct comparison of such bridge:

- would matrix spdif2 be better than pro3z
- can mucholder hiface evo 2 with added hiface clock be betta than pro3x and matrix spdif-2

TIA and cheers.

Richard

I believe the correct model is USB2G4LEXT2.. there is a currently active thread at US Audiomart forums which has a lot of cool information.. (I think an older one here also..) this could get somewhat expensive as it seems best performance requires upgrading the power supplies at both ends. This seems a good idea if you need a longer distance USB extension.

I got one of these and works great.. https://www.shenzhenaudio.com/singxer-uip-1-isolate-processor-usb2-0-usb-interface.html
This probably benefits from the cleanest power you could afford also..

You should be able to pick up a used Intona pretty cheap I think... they work well, but may benefit from some sort of additional reclocking after the isolation.

I think the best current value is the Uptone Audio ISORegen as it includes isolation and decent USB reclocking... Uptone is pretty good handling international shipments also, from my experience I would advise their cheapest option, but you can ask Uptone for their experience to your country... again can probably get a used one at a good price as folks sometimes change to SOtM stuff..

Hi Motberg,

Was to pick up the uptone iso regen on abovementioned application but read the audioscience thread and held back as Amir concluded that it does nothing.

Moreover, I am do not know if these usb gadgetries on usb power will stick make any difference for my use case with already car's 12v car application and none of repeatedly mention noises from smps that I think does not affect or with minimal effort.

Comments and advice most appreciated .. I just start on these digital stuff but still have garrard 301, 401 and michell gyrodec with various rb300, sme iv, sme vi.vi, 3012r tonearms.

Cheers.

Richard
