Anything based on XMOS will destroy the DI-V2 in performance due to technical superiority -- largely because it uses discrete clocks for 44.1 and 48kHz multiples (22.050 and 24.576 MHz, respectively iirc) resulting in far less jitter.

 

Has someone posted actual measurements or some kind of genuine technical data to confirm this? Or is this statement just based off things you've read on the web? I have the Calyx DAC here, which uses an XMOS chip and, to be honest, it isn't as good as all the reviews have said it is. If I can find a firmware update, I'll try and see if it improves at all.

Do you think it is appropriate to suggest someone is deaf in this way? I don't. Making a legitimate query, such as "I don't understand why Kingwa doesn't use an XMOS chips over the Tenor." is reasonable. I was actually going to email him the same suggestion about the XMOS chip, but, from experience realised that he has probably already tried it and that he always has good reasons for the choices he makes.

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

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.

 

As macrog is an audio dealer, he isn't permitted to post subjective impressions of products he sells. If you search the forums for the Reference 7, you'll find a thread that includes discussion of the Master 7 at the end, including comparisons.

We may not design the DI with the USB32 + DSP.

But I think do the upgrade for the users in later,  maybe that will need shipping back for the upgrade.

FWIW--   I installed openSUSE 12.2 (kernel 3.4) alongside win7 on my EeePc today. TE8802 was recognized and all I had to do was change the system audio out. Banshee played 16/44 files without a problem cannot say the same for 24/192.

I for one, will have no problem shipping back my DI-DSP (Te8802) for a swap out to USB32. Thanks for considering this Kingwa - let us know if/when you're ready.

Same here, hopefully I won't have to send the PSU back too.

I remember he made such a comment in his forum on his website (The forum is only in Chinese). It seems he deleted the original DI-DSP discussion thread. As a result, I couldn't provide a link to you to justify my statement. Anyway, another Chinese audio designer Yulong also chose TE8802 over XMOS (not sure whether it's due to cost reason or sonic reason).

 

I upgraded my USB input chip from TE7022 to TE8802 on the DAC19-DSP and soon I'll be comparing my DAC with a XMOS based DAC ...

I'd really like to hear your impressions!

*****Feature Request*****

 

 

Could the next DI have an AES \ EBU output as well?  All of Audio-GDs high end DACs has this input.

Looking forward to reading your review about that.

 

I wonder if the DAC19-DSP would do better with direct input into TE8802 rather than using the old DI + PSU, did you try comparing something of the sort BTW?

In theory TE8802 I2S to DAC chip should be superior as it has a shorter signal path. I sold my V-Link a while ago and don't have another USB to SPDIF converter on hand right now. But the XMOS DAC can be used as a USB to Coaxial converter and so I can compare that way as well in a week or two.

I have a question, is anyone using the DI with the Te8802 chip or USB 32 chip with an iMAc?  I am considering getting one but just wanted to get some feedback from mac users.  Thank you

Im using my DI-DSP (TE 8802) with my iMac and have not encountered any problems at all. Everything works flawlessly and no driver installation is required. Just plug and play. smily_headphones1.gif

Hello DK

 

Have you checked the DI-DSP with Audirvana to see if it's Integer Mode Compatible??

To reiterate... The TE8802 used with my Squeeze Box Touch (Linux) with the USB+192 software update has worked great and without error for 3 weeks

post #3330 of 4021

Well I tried the new 1.1 drivers on my PC (stupid me, 1.0 was working fine) but then it gave me issues saying the USB Device failed... so I uninstall, restart, install 1.0, restart and now.. the same thing... so now neither verison works for me anymore

 

GAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

 

What do I do now?
