I have connected my Condor CP498A to my G68; it works fine. Since I have also updated my DSP6k with latest firmware, the sound quality remarkably improved in terms of sound stage and details.
Now, the loud "click" sound upon powering on disappeared; however, intermittent "click" sound in much lower volume still persists. The occurrence frequency is about once every several hours. I am seeking some help locally. If anyone here knows the details, grateful if you could advise. It looks like some capacitors have a problem.
The hottest spot on the CP498A was about 42 deg C while the ambient 18 deg C. The current drawn by G68 was within the specification of CP498A.
After the problem of the intermitent click sound is solved, I will update the progress here.
Nick: Thanks for your advice
