Simplifi Audio - DSpeaker 2.0 ultra power supply

In past threads I have made excuses for Tim only because the Dual Core 2.0 was a big hit and production was low. Dspeaker should be able to handle demand by now, but to not have an accessory that is exclusive to Simplifi is inexcusable!
Contact Dspeaker with your complaint and perhaps add links to other complaint threads.
When PP gets your money back to you order an Astron SL 11A linear power supply for about a 75% discount to the cost of Simplifi's linear PS. You'll be very satisfied with one.

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.

@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,

Yes it does have a large transformer!
I recently took over my daughters bedroom as my listening room, with no dedicated outlet in that room yet.. When I would dim the lights on the ceiling fan there would be a buzzing through the speakers. After I hooked up the 11A the buzzing stopped.
Fantastic for 12vdc gear!
Do tell what you hear.

Ozzy,
Give it a little time and put the wall wort back in and do a comparison. For sub only there might not be all that much difference. I use mine as a dac, room correction, equalizer, and preamp. Adding the Astron made a big difference across the board. As always YMMV.

Tim helped me extensively back in the fall of 2012. At that time he was learning about the many different and amazing things that the Dual Core can do, and passed on what he found out to me. I use my Dual Core as a full on dac,preamp, and room correction device. At first I thought it sounded hard with the wall wort ps, so I put it on a battery ps and the improvement was very noticeable. A couple of months ago I purchased an Astron SL 11A and it took the Dual Core into another league! It ran me $114.00 delivered to NJ, and all you have to do is make a simple DC power cord.

Tim has been talking for some time about Youtube tutorials for the Dual Core, I guess we'll have to wait and see....

I leave mine on 24/7...IMHO digital sounds better powered on all the time.

@Islandman2000-I had a conversation a while back with a guy who repairs Astrons and he told me to look at 7A or higher, apparently the build quality is better and the transformer is beefier.

@Ozzy-The Astron is analog, that powers a digital device, Dual Core 2.0
