General:
This special Jadis JS1 came to us from a large collection that was meant for use in a reference system, but unfortunately it never materialized.

It was unboxed and fully tested here at SkyFi, but was never actually installed or used.

Handmade in France around the year 2000 with a list price of $18,000, equaling about $27K in today's dollars.

This early version of the formidable redbook DAC utilizes tubes in the audio section AND the power supply.

Later versions used solid state power supplies.

If you intend on using this just for CD's, don't bother with the later versions that are meant for streaming. This is the *TOP* of the top for achieving the best performance possible with standard CD's.

A perfect match for our Jadis JD1 Transport that is also available for a killer combination.

This JS1 comes to you complete with all of its original packaging and accessories as if it just left the factory.

Testing Process:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect resistors and other passive components for signs of overheating. 

After the visual inspection we connect the DAC’s RCA outputs to our Sencore PA81 Power Analyzer which simulates a real world input impedance and allows us to monitor the output on an oscilloscope. We are equipped to test optical, coaxial, and USB inputs at Redbook CD Quality. We start with a test signal to verify signal lock and proper output on both channels. If the DAC has balanced outputs these are also tested at this time. If the DAC has multiple Optical and Coaxial inputs they are all checked for proper lock. USB inputs are tested with a Macbook Pro. 

After proper function is verified, we set the DAC up for a listening test to evaluate general audio reproduction quality and monitor for clicks, pops, or any other audible signs of issues related to dropped signal lock or failing audio output stages. We often connect DACs under evaluation to our long term test rig for a long test stint to verify stability under real world operating conditions.
