The schema had some typo, here is the correct.       What's different between these popular chips 　 　 Dual WM8741 ES9018 AD1955 AD1852 WM8740 SNR 128 DB (Mono) 120 DB 120DB 114DB 117DB DYNAMIC RANGE 128 DB (Mono) 129 DB 120DB 114DB 117DB

Quote: The problems is on the ES9018 , while it accpet the I2S, it had very rigorous request the I2S signal because its I2S input pots are without the master clock input. I asked an engineer work for  another manufacturer, he said in their gears , the I2S input will change to SPDIF then...

The web not down, maybe some reasons block oversea link to it. We will change to an USA serve today, hopefully can keep the communicate without block.

Quote:  I think you can catch it before 10th Nov, dual WM8741.

Quote: I don't know if I this reply is proper at here. Before the end of last year we can through agents application a factory price low than the standard quote if we got enough amount, like more than 2000 pcs, so why the audio-gd 1704 built in gears so cheapest . But now we can't, it...

Yes the NFB-7 must the last dedicated DAC of 2010 . In whole month I was watch very lot stateside filmes every days cause I can't working for design. Like the Star War even though I had watch more than 10 times but I rewatch again recently. Any new products must design at least 2-3 months...

  Quote:  The Cables were  upgraded. Inside still Shark cables. But fit in a black netting for reduce the librate effect of the signal .

Quote:  At 120V , The RE7 is 39.5W. Same with 240V station.

  Quote:  The RE7 power draws 38W at 230V is correct. The RE1 is 45W at same voltage. The HE version is 95W for both models.

Quote: The ACSS to XLR made the DAC output impedance at around 1.8K ohm, this is a quite large output impedance in now . The sound easy effect by the caps of the cables , and the amp input usually has a low pass filter which is built by a resistor and a cap, the 1.8K ohm output...

  Quote: I must say your thread is enough funny. Even the cheapest Sparrow, the input signal select by very near logic switch, the selector on the front just control the logic switch.

  Quote: I don't think this "gentleman" is me. But today (Sunday) our office only me is a gentleman and a technician on duty. Maybe that was a lady? The transformers can't flow out any smell unless it near burn die.  

Quote: TI was advice the PCM1704 power supply with the analog parts. At first I misdoubt and  I  built the separate digital and analog power supply for PCM1704 but that is a degrade obvious.  

  Quote: I think you had mistake of my Chinese words. I interpret our Email to English as follow:   The NFB1 sound quality is quite near or maybe equal to RE5, But I don't think the NFB1 can over the RE5. Both have pretty equal in the soundstage and detail. But slight different...

A skilled designer as a kitchener. Kitchener can cooking the foods slight mild, or dense. There hadn't a rule must cooking the fish to only  flavor. Just different amount sugars and salts. If people think the Reference 5 flavor is better, the designer can easy adjust the NFB-1 to quite near...
