Do you have a transport or other device you can try running into the Pontus? If you tried the Lumin through it's Dac then you tried its analog outputs and not it's digital output.
Pontus 2 not working.
Went to play a song and nothing happened. I am using my Lumin D2 as a streamer. Noticed that the lights which indicate number of KHZ and multiplier were not lighting up. After checking all my cables etc. I removed the Dac from The signal chain and hooked up to the Lumin D2 which has it's own Dac and it worked. Any ideas whats wrong with the dac. The lights for my options, phase, and oversampling all iluminate. Thxs Art
