Dave Elledge sent me populated boards and told me I had to build these out and listen to them. I've learned from experience if Dave says to listen to something then there is something special going on. I've learned a lot form Dave and one of those things is to trust him when he likes something.
I built a pair of amps as mono-blocks a few years ago using these same chips and the results were exceptional. I like the off the grid systems for the zero noise floor and for the fact that they will sound the same no matter where I take them (Audio shows...). Here is a link to that thread: http://www.audiocircle.com/index.php?topic=124981.msg1317309#msg1317309
I think that the Folsom version takes them up several levels by design of the boards much better and with support of assembly. It will be interesting to compare this version to the pair that I made. The power supply is really nice, but I have an expensive power cables on it, plus a balanced power supply from Dodd Audio, and an Uber Buss from Dave Elledge. So three of four thousand dollars worth of conditioning verse a $200 100 amp hour Power Sonic battery. Which will I like better? I don't know.
I mounted the amp part in an Aluminum chassis that Gary Dodd designed before he passed away. I have a lot of them.
Somewhere I have a box of on/off switches that fit the front baffle of the chassis. The on/off switch lights up when turned on too. At some point I'll find them and replace what I used with what belongs there.
I used a Neutrik connector for the DC power in. I used Caradas RCA inputs, and tube connectors of coarse. There was no way I'd ruin it with binding posts.
The input wire is Vampire's continuous caste Copper. The input coupling caps are Sonicap Platinum's. The speaker wire is our internal wire that is solid core Copper in polyethylene. The power wire is OFC Copper in 12 gauge.
I have interconnects from High Fidelity Cables. http://www.highfidelitycables.com/
It's there entry level $1,600 a meter pair version. And the speaker cables are from Electra Cable, B6 model. http://www.electracable.com/speakercables.htm
I made the DC cable using a braided 6 wire configuration of Silver Coated Copper.
I put the power supply in a separate chassis.
I put the power input on one side and the DC output on the other side. And I put a power switch on the input side.
Dave populated the boards before sending them to me and there is no telling what extra's he did to them.
I turned them on a little bit ago and they are up and playing with no issues. They sound great immediately. Now to let them burn in for a while. Those Sonicap Platinum's are going to take a while....
So more on this after some play time.
