Absolute sound review: http://www.theabsolutesound.com/articles/tortuga-ldr3v2k-passive-preamplifier/
The unit has: 1. upgraded Neotech UP-OCC 26AWG wiring all-throughout 2. Has custom firmware to have INPUT-1 behave as HOME-THEATER by-pass (ie fixed at 1.0 gain). I paid additional $ to get this done and of course it can be reverted at the buyer's expense.
My impressions: - Given that most DACs and sources can output very large volumes (if directly connected to a power-amp directly), most people dont need gains larger than 1.0. This is the best preamp that is as close to a plan wire as possible.
- This has the most holographic imaging of all pre-amps that I've used. - This is some cutting-edge technology that uses light-dependent resistors that results in high-precision and utmost clarity in the signal.
