Dear Mr. Keetekawee Punpeng! There is happiness! The “Fidelizer” program is installed and does its job. The sound of the audio system has been taken up a notch. The sound image is more extensive, more defined, more lifelike and more musical. Thanks again for that!

The system: HP Elitebook, Gustard A-26 DAC, Audiolab 8300A integrated amplifier and Canton loudspeaker. Music comes from Tidal.

Best regards: János Király from Hungary
