The version B update replaces the original power board on the V3 Max power board with a more robust, quieter and …
What if, after 180+ years of mechanical pots and stepped attenuators, there was another way to approach high performance audio volume control?

Tortuga Audio plans to release its new LDR300.V25 Buffered Preamp on August 28. The LDR300 is a remote controlled, singled-ended, active preamplifier that combines Tortuga Audio’s popular LDR (photoresistor) attenuation technology together with a powerful JFET output buffer to deliver robust sonics that will satisfy the most discerning audio enthusiast.
In this article we take a closer look at what’s going on behind the active vs passive preamp debate and hopefully develop a better understanding so we can all make wiser choices.
