Keep the Ref-D near enough to it and do #4. Its a specific piece of hardware, you will only know if it matters to you after listening between #3 and #4. If the on board PSUs don't draw constant current then there is still play on the connection runs to their mother PSU (wiring + traces). How insensitive the on board ones are to that remains an open tiny itchy question.A question about the best way to hook up a Reflektor supply if I may...
I'll be using a Reflektor to power an Acko SO3 digital clock/isolator board, which has three power supply connectors (for separate onboard power supplies).
I could;
Does it matter that much with the SO3's onboard power supplies anyway?
- run separate wires (including sensing) between the Reflektor and each of the SO3 power supply connectors.
- run wires (including sensing) to one of the SO3 power supply connectors and then daisy chain just the power supply wires to the other SO3 connectors.
- run separate wires (including sensing) to a point close to the SO3 and then split out power supply wires to the SO3 connectors.
- connect the sensing at the Reflector and run power supply wires to each SO3 connector.
Thanks

Hello all!
I have DAC LKS Dual ES9018 MH-DA-002. It has the analog output section with specially designed all-discrete parallel power (150mAX2 full discrete Class A parallel power circuit, the current source + amplifier + Wallman mirror circuit Billiton frequency). What shunt regulator will be better for this:
1) BIB SSLV1.1 IRF+
2) Reflektor-D
?
Salas wrote on previous pages that BIB has more dynamic on analogue http://www.diyaudio.com/forums/power-supplies/261031-reflektor-d-builds-17.html#post4093703 . So what regulator will be better for output stage?

BIB for its analogue section, Ref-D for its digital section.
so for output the BIB regulator will be the best. But how about AVCC lines of digital chip ES9018. There was one test between:
1) LT1086-5 considered a very good series regulator for audio
2) A very low noise shunt with no op-amp similar to Salas design (1.0 version)
3) Tent Labs shunt
Choice 3 was the best (dual opamp shunt). So what will be best for analog lines of ES9018 chip - BIB or Reflektor-D?

I like to use Reflektor D to power +V and -V UGS v3 preamp boards
what would you recommend to use for negative shunt
two positive boards stacked like http://www.diyaudio.com/forums/powe...-voltage-shunt-regulator-652.html#post3972490
or negative board like http://www.diyaudio.com/forums/powe...-voltage-shunt-regulator-429.html#post2724088

Hi Nautibuoy,
I'm trying to figure out how to get around 5.25Vout, 350MA CCS current for my Buffalo II DAC. Which configuration did you go for? Could you share a photo of the board, please?
Kind regards,
Sonnyboy
Hi Sonnyboy, the values I used are detailed here;

I don't have any pictures to hand but I'll see what I can do, though you shouldn't need them to build the regulators as Salas's build guide is comprehensive.
Ray
Thanks Ray. I was wondering where you put the 56 Ohm resistor. Is guess you put it in the RX/J/D slot?
Orson (AKA Sonnyboy)
Yes, across RX/J/D - you can see this position with a wire link in the picture on page 1 of the build guide, just substitute the resistor for the link.
I suggest that, before finalising your Reflektor build, you install the resistor temporarily and test/measure using a dummy load (as per the build guide) to ensure correct operation and output voltage.
