This is an Abacus Music LDR using the latest hardware and firmware from Tortuga Audio. This is a fantastic passive preamp that has beat out costly active devices in my system as well as several TVCs (transformer volume conrol). It comes with the Apple remote and walwart, but also included is an outboard linear power supply that improves the performance of this already great pre. It has one output and three inputs and dual digital display. The firmware allows for many adjustments including the ability to change the input impedence to tailor the preamp to your sources.
Asking 450.00 which includes the upgraded power supply.
