Will RS-20A work with the tpa3116 based amps?
. . . . <snippage> This 7a went for $19.99 plus $3.94 for shipping. <snippage>
I have the Ten Tec 937 on a TBI Millenia and an Astron 11A on a Dspeaker Dual core 2.0. Tomorrow I'm putting in an order for an Astron 11A modded to 9vdc for use on an iFi iTube, and hope to have it by weeks end. Before the 937/11A ps's I was using a custom battery ps with what I thought were very good results. OzarkTom had mentioned that he uses the 937 so I gave it a try and I'm glad I did. Immediately I noticed a huge difference in sound quality that is so substantial I had to get another one for the Dual Core.Rodge, could you go into a little more detail about the sound difference of the Dual Core 2.0 with the Astron? I am trying to improve my Dual Cores transparency that I am not happy with. I am trying to spend as little money as possible to see if I can improve it. So far my FAT DAC (Firestone Audio Tobby) is superior as a DAC, especially in the area of transparency. If I could improve that then I would just use the Dual Core as an all-in-one solution. Even when I switch the Dual Core to "by pass" and run my FAT DAC through it there is a noticeable diminishing of transparency. Taking the Dual Core out of the chain altogether makes a big difference. So I mostly wanted to know if you noticed a difference in transparency using the Astron? Thanks!
I have had my Itube hooked up the Astron SL11A, modded by the company for 9v, for a few weeks now. Before, I was getting some decent sound with the Itube, but I was not ready to hear what it sounds now.Itt is much larger soundstage, more holograohic, and much more natural sounding. I feel the Itube has actually improved 100% or better. Of all the tweeks I have ever done in my life, this is the most improved that I have ever heard and it cost me $114 to do it. I could have bought a thousand dollar speaker cables or power cable and the improvement would never have been this great. I strongly feel this Itube-Astron combo would improve any system regardless of price.
Tom, have you tried the Astron 11A with your modified TBI amp yet, I picked up an 11A that you posted about to try but haven't had a change to connect it the two amps I have.Thanks,Greg

Thanks!Hi islandman,To better answer your question could you please post the other power supplies you are using?As noted in the other half of my post that wasn't quoted, details/transparency (to me they are the same thing) were also clearer. The Astron linear power supplies are inexpensive to purchase new and are even a better deal used. You could purchase one on Ebay, and if it doesn't sound better resell it.
To conserve shelf space I'm considering attaching a TPA3116 in a case on top of an Astron RS-12A. Thinking I would run new internal leads through the top of the Astron to the TPA so as to avoid the external screw down connections. How does this sound?Am I correct to assume Astrons store lethal voltage even after being unplugged?
I can get another Astron for $5 bucks at a elec recycling placeIts an Astron RS-7AIs the Astron RS-7A enough power to drive "both" TPA 3116 and the Magic Sound Buffer 6N3 x 2 + 6Z4 Tube Preamp AMP?

I have no idea what you're talking about, but yes a 7a unit will drive two 2a units and one .25-1a unit just fine. What may or may not go over well is possible loops.
