Gustard U12 USB Interface 8 Core XMOS chip

  It's really a new topic for me. 'tanly_tech' of tanlyAudio claims if you connect 'tanly usb interface' to your DAC via XLR, then you don't need to hook up the external clock.

Very cool!  It can send the master clock signal to the DAC by AES spdif

Rb2013 would I gain any benefits moving away from the peach tree audio X1 to spdif converert other then it being in the way, to a unmounted Gustard U12 or that other one that was mentioned?

I think certainly yes - see the earlier pages - I believe some tried the U12 with the X1 and had good results.  For $150 the U12 is screaming bargain.  PM and I can sell you one of mine with better caps.  For $230 the MXU8 is better.  Your money your call.
 
  I wonder whether Tanly Audio usb converter I2S is compatible with W4S or PS Audio dacs. It's LVDS. But if the channel is swapped like the Gustard U12 and W4S.

I think the MXU8 is like the U12 - maybe a XMOS issue?

Oh no you didn't!

  It's an embarrassment of riches. Like I said we are living in an audio golden age.

I believe the channel will swap like U12 and W4S cause almost chinese i2s to hdmi module are all the same.

Just wondering why no one try to convince them to make it with PS Audio standard.

I will give Tanley a try if they can change their i2s pin like PS Audio.

Almost forgot to report the polarity tested with U12. Well, I failed the blinded test even when use spdif(coax) output. So, you need some one else to do the polarity test.

As posted previously, pin 1/3 and 7/9 are in inverted phase in U12. Nothing to do with XMOS. From Gustard's viewpoint, PS Audio assignment is inverted. Ask Tanly about their pin assingnment.

It has no I2S connection which the most important connection since it's DIRECT connection to DAC-CHIP, without interference of any transformer (Pulse / Murata) and clocksignal wil be derived from I2S signal.

I2S does ALWAYS, it's native within the spec, thats why I2S is most preferred signal transfer between source and DAC.
 
QUOTE:
The most important advantage of this connection is to avoid the double conversion from I2S to S/PDIF or AES/EBU inside the CD-Transport and vice-versa inside the DAC;
with the I2S connection the Master Clock is generated inside the CD-Transport and all the signals are synchronized with this and sent directly to the DAC.

QUOTE:
The main advantage of I2S is the separation of the word clock from the rest of the digital signal. Theoretically, this will allow for lower transmission jitter, same as the separate word clock connection on some pro gear offers.
Of course, this facility must exist at both ends of the connection.
