Being a true passive preamp it is unity gain with no amplification or buffering. The LDR3.V25 is an updated version of our popular LDR3.V2 model which The Absolute Sound awarded its Golden Ear Award in 2016. The updated LDR3 incorporates our new and improved V25 preamp controller that uses LDRs (Light Dependent photoResistors) for exceptional audio performance. Enthusiasts who value a dead quiet preamp with a deep dark background between the notes, exceptional transparency, and pleasing dynamics, will find the LDR3.V25 to be a very satisfying preamp rivaling many high end peamps at a fraction of the cost. And it comes with a simple remote control so you can relax and enjoy your music in comfort from your favorite listening spot.
