Free Shipping (Contiguous U.S. Only)

General:
The Jolida JD100S is a very interesting and highly regarded CD player, first one to arrive in our shop.  Key features include a precision Philips transport and a warm yet detailed vacuum tube output stage. We have had its sister player the JD100A and have always liked them and the JD100S is no different. 

This particular example is loaded with a strong set of vintage Amperex and Sylvania tubes. The tube output stage helps deliver a smooth, detailed, and natural listening experience that sets the JD100S apart from many conventional CD players. In testing we really enjoyed it.

Additionally, a brand-new drawer belt has been installed, so the disc tray opens and closes quickly and smoothly as intended. Functionally the unit is ready to be enjoyed for years to come.

Included is a reprinted copy of the owner's manual on heavyweight paper for durability and ease of use.

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. When the unit is first powered on we check the drawer mechanism function.

After the visual inspection we connect the CD Player 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 start with a test CD with precision test signals to verify proper output on both channels. If the CD player has balanced outputs these are also tested at this time.

If this check passes, we move onto evaluation with actual music CDs. We listen for clicks, skips, and drops during playback. At this time we also check the transport functions including Play, Pause, Stop, Repeat Track, Next Track, Previous Track, Fast Forward, Rewind, and programming if applicable. If the unit has a remote control, all remote control functions are verified.

If the CD player is capable of SACD playback we test its ability to read SACD layers on multiple discs including standard and hybrid SACD's. At this time we also check the unit’s digital outputs where applicable. If SACD layers are being properly read we should see the digital outputs mute during playback. On redbook CD playback we verify that each digital output maintains proper lock on our bench DAC.

After bench testing is completed, CD players are set up for testing on our long term test rig. During extended testing we make sure that unit can play through several different discs from beginning to end with no skips or lockups.
