Don't know but I would guess yes

When was this? I don't recall him ever comparing it to XMOS. He would have to be deaf not to hear the superiority of even the reference design XMOS over the TE8802.

when did you make such a comparison?

We have got the demo and sign the NDA in Nov. 2011.

They have some lot chips model but this is the best one of them.

The demo have I2S output pins and SPDIF which is easy for the test.

Somestranger26 have you listened to the USB32? I think it is great. What makes you think the Xmos is better than the usb32?

My Master 7 sounds better via the USB32 input than my Audiophilleo 1 with external PSU or my M2Tech EVO with external clock and battery PSU.

I am hoping there will be a Master series Digital Interface based on the usb32 with I2S and AES/EBU outputs

Was the TE8802 better?

Also, will you release a USB-32 upgrade module for those who have troubles with TE8802 Digital Interface?

Yes, USB32 seems pretty good (based on initial USB32 vs. audiophilleo2 comparisons on NFB-11.32).

 

+1 for Master Digital Interface

Wow, you have the Master-7. Can you describe the sound of it? How does it compare with other DAC, e.g., Ref7.1? Great to know USB-32 is better than AP1, that's a really BIG statement.

Damn that sounds pretty impressive - so thats better than AP1 with AQVOX and no galvanic isolation (I don't like galvanic isolation before the USB input)?  

 

That would put it ahead of XMOS reference designs such as in W4S DAC2 etc. as with some of those designs people seem to prefer using external USB transports.  Sounds promising, USB transports are good but the SPDIF-I2S conversion is only so accurate in terms of jitter performance if you check the specs, so there are potentially scenarios where built in USB-I2S like in the Master 7 etc. could bet better.

I own both and have compared. There's no point really, since my V-Link 192 is in another league.

No, but the advantage the USB32 has is likely due to it having a direct USB-to-I2S connection internally. I'm a bit surprised that you say there's such a difference, but eliminating SPDIF from the equation is a huge advantage. Just a hunch that it's better than USB32 if you had them both connected the same way, so enjoy.

Interesting!!! looking at the picture of the PCB, it has two XO (means separated 44.1KHz and 48KHz sample rate multiplier) and also has I2S connection holes for direct I2S out...

well, imho, the only reason to get DI is its DSP.

as i see, you you've got a DI without it, so it's not a fair comparison.

I feel the DI-DSP is at least as good as the AP2 I had, then again both were only subtly better than optical out from my computer card (I have the DSP-1 in my Ref-8 though).

confused.gif How is that the only reason to get it? The original DI had DSP and I never used it. Kingwa himself said it makes hardly any difference unless upsampling which is down to preference.

This would be MUCH better if you want to go the DIY route like attaching an I2S cable: http://www.diyaudio.com/forums/digital-source/188902-xmos-based-asynchronous-usb-i2s-interface.html

That is what I am waiting for.
