Simplifi audio has been the absolute worst audio dealer I've ever dealt with. I bought the $500 power supply for the Dspeaker 2.0 seven months ago - still haven't received it - and he's refused to respond to any calls or emails. Working with paypal to try to get a refund - but he doesn't respond to them either - so taking forever.
I should have known better - had a lousy experience buying the DSpeaker from him as well - took 3 months, but at least I finally got it.
Everyone says what a nice guy Tim is in person - and I'm sure he is - but this is a terrible way to run a business. Stay away from buying from him. Know lots of friends that gave had the same experience.
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.
@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
