I may going to China with local Audio-GD selling agent to meet Kingwa and his staff on April 17th.  There are many opinions on i2S compare to others.  But what I can say one thing is, for RE-7 and other Audio-gd DAC, i2S can give far best sound than other input methods.   I am from Seoul...

Quote: I have a couple of high-end digital cable from Siltech and it is still could not compare with i2S.   CD7FV is CDT which is same as DDC for Audio.  CD7FV may can mod to install i2S sending board to connect to DAC.  DDC is for PC-Audio and CD7FV is for CD listern.  From...

  Quote: Yes, I am working on NFB-7HE which is two pieces version of NFB-7.  It seems working fine.  (Update: it is not possible because of ESS dac IC)  For selection, you can choose any input to make i2S input.  My case I use USB selection to be i2S selection.  One interesting part...

  Quote: To maximize sound quality of Audio-GD Referecnce Series DACs, I think we may seek to invest some $$ on source area.  For PC-Audio base, I think DDC and to use i2S protocal between DDC and DAC is one inverstment to maximize sound quality.  ^^*    

Quote: I use Neutron Star on master clock in ProFire 610 and D-Clock for JetPLL chipset.  ProFire 610 is 1394 firewire unit and it is Async.  For RE-7 or RE-7HE, you do not not need clcock because 1704UK is Signmagnitude DAC chip.  

  Quote: Now, I am trying to modify NFB7.  I can have more detail modification point by one or two weeks.   For Profire 610, I can provide detail of modification or even i2S transmitter board with instrunction.   Please just wait 2 ~3 weeks for more detail plan.   Thank...

  Quote: The i2S sounds much better.  The biggest point will be staging.  To switch between Coax and i2S, there is big differences.  I can bet if someone hear i2S sound, he/she will also choose i2S instead of other methods.   For TC electonics Imapct Twin, there is problem to...

  Quote: At this time, I need discuss with Kingwa.  Currently, I have built several Audio-gd product upgrade kits.  Let's see.  ^^*  

  Quote: I am very close friend with Audio-gd selling agency in Seoul, Korea.  He and I will discuss Kingwa about this modification idea.     For FUN, I have built a board to use WM8741 dac chip instead of FUN original WM8740.  After my modification, Kingwa has changed his chip...

Quote:   Yes, I listern with ACSS.   For RE-7HE, in my opinion, the internal power wiring is too long for the best possible quality sound which RE-7HE can do.  After I have put DC-DC converter, the sound improve much better.  I have compare with many other top DAC, but not even...

This is my i2S receiver board.  I have design for FUN and it works fine with RE-5 and RE-7 also.  I use Toshiba Logic i2S chipset.   I have printed Audio-GD name on all of my modification boards as you also can see my DC-DC converter board.  ^^*     These are sender boards for i2S. ...

My new RE-7HE Modification.   This is origonal inside pictures of RE-7HE.     You can see there is empty area on upper area of DAC part unit. (Left Unit)   I have build a DC-DC Converter and put inside that empty area.       I also put i2S input module and change...

I am currently using RE-7DSp with PS Audio PPP and there are definetly improvement from normal wall plug-in.   I will re-design my multi-plexer PCB to improve my i2S input sound quality on RE-7DSP.   This is my configuration of my PC-Audio setting and I can say this configuration can...

ccschua,   JET PLL 1394 DDC - There are some pro-recording equpiments with JET PLL DiceII chipset.   About JET PLL   http://www.tctechnologies.tc/index.php?option=com_content&view=article&id=10&Itemid=14   M-Audio Profire 610 Weiss INT 202 Impact Twin etc...   I have...

Compare between i2S and Coaxial...   The i2S is far better sound than Coaxial or Optical.   I laso have modi JET PLL 1394 DDC for i2S output.   At this time I am still modifying i2S output.  I am using Motorola chipset now and will try Toshiba new chipset to improve i2S output...

This is little(?) modi of my RE7-DSP.   The sound qulaity iis "the best sound quality from any other DDC + DAC by far!!!"   - CMC Super CU Silver Plated RCA Sockets - HGA Single Core 4N Pure Silver wire - i2S input Modification - Capaciter Shielding & Anti-Vibration Modification...

RE-7DSP with i2S input.   Connect with JET PLL 1394 DDC function.  The sound quality is that "no other DAC can meet sound quality by far."   - CMC Super Cu Silver plated RCA Sockets - HGA Single core pure silver 4N wire - Main condencer shielding & Anti-Vibration modi.
