I started from this post. I am in the process of stripping down the assembled AK4396 board and assembling an AK4393 kit.

If you haven't purchased, buy the kit!! I already lifted a few pads due to the crazy amount solder used The AK4396 will be used for direct out, and the AK4393 will be with opamp. Still waiting for the parts to come.

Direct out might be the wrong terminology.
What I meant was to take the signal directly from the dac and feed that
into either a cap, or transformer, or nothing at all into the preamp.

There were some discussions in previous posts of various approaches. This is
just to satisfy my curiosity of how each approach will work out.

Certainly try things for yourself as its the only way to learn, but I have a strong suspicion that this output stage from this earlier post is the way to go...DAC 2496 (AK4393) DAC KIT With CS8416+AK4393+5532

WM8805 is the only receiver worth "upgrading" to. IMO not worth mucking around with a DIR9001, although the DIR9001 is better than CS8414.

When this output stage is running correctly ,this solution is not so bad !!
Actually I have some problems , i have checked different power supply values ( +/- 15v , +/- 20v ) .......... and the stage is not stable

This output stage is followed by an Headphone amp ( WOO6 ) ,when the potentiometer of the WOO6 is on the left ( No sound ) the power supply values are very strange .I have not the good values less than the settings .

When the potentiometer of the WOO6 is on the right ( max sound ) the power supply values are good !!


Thanks for your advices

Serge

Try putting a 1K resistor in series before the 1M gate stopper. Perhaps also try a 300 ohm on the output. Perhaps you are getting oscillation?

eg. DAC > 1K > Gate stopper > FET > FET > 300R > headphone amp

Thanks for your advices .With a 300 Ohm on the output it's stable .But no sound

The AK4396 is dead

The 5v on the AK =0 v .The power supply is good when i disconnect the 5v wire from the AK .I have 5v on the power supply .
.......I am a big STUPIDO

Check for a shorted capacitor or solder bridge in that 5volt line.
