Question, If I want to wire in parallel do I just duplicate the cables to the IEC (obv. from the other side) and do the same for the switch. e.g. as if I was to run a single SMPS and Switch and double the wiring ?

Hi,

To answer you, pay attention for the correct wiring (you reversed the phase and neutral !)

Now if you want to add a switch Led, please follow this diagram (from Stand By connector)

And my opinion for simpler assembly (make it easy ))):

Lock Standby connector like this and use a 220V / 110V LED instead with an IEC Switch ON/OFF )
EMI* : is optional

I’m close to finishing up my stereo sample build, while I wait for my micro audio smps1ks with Mundorf caps for the 4 channel version.
Had this spare 400w 48v 8.3a power supply kicking around.
Using the same EMI filter that Jeff Rowland uses in all of his $15000-$20000 amps lol.
Here is the final layout. Just got to solder the inputs and clean up the wiring.

Hi - this looks like a great project - your build looks great!

Do you know if I could drive this from a Topping E50?

thanks!

Get the SMSL D6S instead
XLR outs can be set @5Vrms or 4Vrms >If you have other projects in the future, it will therefore remain more flexible
@5Vrms this DAC performs about 124db SINAD ! awesome )
