It's taken a bit longer than planned but we're pleased to announce that the LDR3x DIY Preamp Controller Board has been released and pre-release orders are shipping!
The LDR3x allows you to build your own high performance LDR based passive (or active if you include a buffer) preamp that can be controlled remotely and also locally via rotary encoder/switch or discrete pushbutton inputs and a simple potentiometer.
Built around precisely matched digitally controlled LDRs, the LDR3x offers the DIY'er the ability to build preamp that will rival the audio performance of even the best high end preamps.
We'll be posting more pics next week and tweaking the technical manual which has been updated as of today (6.29.13) to reflect the final design/build. We still need to include more detailed artwork describing the board and the interfaces.
You'll notice from the pic that the board isn't fully populated. The board has certain functionality that isn't available to the DIY'er and thus those relavant parts are not included. We also plan on using these boards in future iterations of our own preamp products.
You can find more information and purchase the LDR3x via the website/store at: LDR3x DIY Preamp Controller Board | Tortuga Audio
You can also find a recent review of our LDR6 Passive Preamp at 6moons.com via this link http://www.6moons.com/audioreviews/tortuga/1.html
to get a feel of what to expect by way of sound quality with the LDR3x. Expect quite a lot actually.

Master Board for unbalanced inputs - $295
Matched Master & Slave Boards for balanced inputs - $495
Tortuga Audio IR Remote - $49
