Simplifi Audio - DSpeaker 2.0 ultra power supply

Is that a drop in replacement? In other words does it have the correct input that goes into the DSPeaker?
Where do you recommend to purchase it from?

The Astron SL 11A is a 13.8vdc linear power supply. The Dual Core can handle up to a 15vdc input. I know this because I emailed Dspeaker and asked what the max input was.

On the back of the SL 11A there are a pair of binding posts one red(+) and one black(-).

You will need to take wall wort to Radio Shack and match up the plug size (can't remember the size at the moment), buy some 18g wire, crimp connectors, and a digital multimeter, all together about $30.00.

On the plug there will be 2 wire leads.

Strip the wire ends and crimp them to the plug wire leads.

Connect the opposite ends to the binding posts on the SL 11A.

DO NOT plug the cable into the Dual Core yet!

Plug the SL 11A into the wall, turn on the multimeter, take the red probe and put it in the center hole of the plug, take the black probe and touch it to the side of the plug.

If the meter reads 13.8vdc then you are in business.

If the meter reads -13.8vdc or 0 then swap the wires on the binding posts.

You should get a positive reading.

Put the plug into the Dual Core and enjoy a huge improvement in sound quality.

Search for Astron and call their customer service, they will give you a number for the dealer in your area or try Ebay.

Rodge827,

IIRC you also tried battery power to your Dual Core. Do you prefer the Astron? How do they differ in their impact on the Dual Core sound?

@Ozzy, yes $100.00 new is a good price, I was including shipping in my estimate price.

@Roscoeiii, Yes I was using the battery supply you mentioned. I bought an Astron for a TBI MG3 amp and the improvement over the battery was substantial, so I thought to try one on my Dual Core. IIRC you are using your Dual Core as a preamp also? The improvement was substantial on the D/C with a wider and deeper sound stage, more detail, blacker background, crazy good dynamics, and much better decay of the notes. The difference is night and day!
As always the standard disclaimer YMMV.
If these things had "Audiophile" stamped on them they would be $500.00.
The SL 11A is designed to be used for Ham Radios, but can power anything within their vdc range.
Hope this helps,
