Incredibly rare and difficult to find FIDELITY RESEARCH AS-1 passive line stage for those who appreciate the purest signal paths in their system. It allows you to feed a pure source signal to the power amps resulting in a refreshingly clean sound unmatched by active preamplifier circuitry.
This simplicity does not sound sterile but rather rich and lush.

The gold plated selector switch has a low contact resistance of <5mΩ and high purity LC-OFC is employed in the internal wiring. Robust RCA jacks ensure a secure connection and the substantial enclosure offers excellent vibration handling characteristics.

The resulting sound is exceptionally clean and free of sonic artifacts often imposed by power supplies and complex circuit assemblies.

The AS-1 remains to be one of the finest passive line stages ever produced. Copy and paste these links in your browser:

This unit is in 100% working condition. I am using it into a McShaned Citation II and it sounds great.

Both attenuators function without any noise whatsoever. The mechanical operations are silky smooth. The knobs feel great to operate.

Gold plated RCA connectors on the rear are in nice condition. 

Some signs of wear, notably on the front top edge, but overall in fair cosmetic condition. Please refer to the photos for a good idea of condition.

Anyone is welcome to hear it in Brooklyn, NY, where it is still in my system. No returns.
