Post S/PDIF audio cable
What kind of cable is needed to connect the 3,5mm S/PDIF output port to a DAC ?

The standard cable supplied with the fit-pc3 works with a Naim DAC but, for instance, the Oehlbach NF 113 Digital, 75 Ohms HF impedance does not seem work with the same device !

I have done some further tests and my conclusion is that the 3.5mm S/PDIF output of my fit-pc3 works flawlessly with 16 and 24 bit, 44.1, 48, 96, 176.4 and 192 kHz files but NOT with 24 bit 88.2 kHz !

Files in this format (no matter whether FLAC or WAV) exhibit severe aliasing problems when played through the 3.5mm S/PDIF interface of my fit-pc3.

One can easily test the interface with the sample files from section "High Definition Frequency Sweeps" on

http://www.audiocheck.net/testtones_hig ... naudio.php

The first file (88.2 kHz) produces obvious aliasing artefacts, the other three sound as they should. The question is whether this is a software or an hardware problem and whether the problem can be fixed. Any idea or suggestion ?

There is nothing to be done with audio codec about that.
Try to update the SW driver.
