Simplifi Audio - DSpeaker 2.0 ultra power supply

Just wanted to say I just bought the Dual Core from Underwood HiFi but Tim has been helping me with advanced calibrations and performing room response readings , numerous emails and phone calls. I believe he is now or soon to be offering free consulting. You send him your results and he gives recommendations. He knows everything there is to know about the dual core. Things the average person, at least me would never figure out through the directions. He is going to try and have Dspeaker put out a video on advanced operation of the dual core it is really capable of so much. The new power supply is only coming out possibly this week. I know he is going to Munich this week. Anyway , I certainly believe your problems but I have only positive things to say and very happy with the dual core's performance for room correction and preamp.

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....

Guys, I just bought the Astron power supply. I was wondering if you are leaving it powered up or shutting it down after listening.
Thanks

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

I read the posts above about using the Astron SL-11A with a Dual Core 2.0 and decided to order an Astron power supply. However, because the Dual Core 2.0 is powered at 500ma I decided to order a Astron RS-4A which is 4 amps. They can be found online less expensive that the SL-11A. Just a heads up.
