One owner, flawless Eva 2 LDR passive preamp...technically it's not preamplifier because the signal is only attenuated via light dependent devices, also known as photoresistors. It has three sets of inputs and one set of outputs and comes with an Apple remote that controls volume (23 steps), mute and input selection.What is LDR technology, you ask? Inside the chassis, a small light shines on the photoresistor. The intensity of the light varies the resistance, which concurrently adjusts the volume. It is the most modern way of controlling volume in the analog domain and is far superior to volume pots and fixed resistor volume controls, primarily because it contains no moving parts or switch contacts which degrade the sound. In short, it is a passive attenuator with no mechanical switching whatsoever. If complete neutrality (no sonic coloration, editorializing, etc) between your source and its amplification is what you seek, there is nothing better. I will include the Apple remote and the power supply, insured ground shipping to any US street address and will also absorb all PayPal fees. Thanks for looking.
