defective pre-amp

Bought a new C47 McIntosh and hooked it up to my Sony UPD800X DVD player.
I have a new set of headphones that are 103db sensitivity. I used a new Pangea Coax cable.
When listening thru the headphone Jack I get lower volume than normal and lots of hiss. I tried 2 DVD player and same thing. Any ideas? bad headphone amp inside or bad DAC? I am next going to try a different cable....

Are you listening to CDs, DVDs or SACDs? Might want to go into the setup menu of the DVD player and try changing the digital audio output to PCM. Worth a shot.....

Thanx guys!  I tried the both adjustments and nothing worked! Baffle now! Any other adjustments. I tried 2 different cables now, nothing! I tried headphones on my computer and TV, they worked great!

I doubt its a bad dac. If its an open box item its best to reset to factory settings and try again. And have you tried another source or output through speakers?

No got it for headphones and to use with my DVD player to play CD's. Only play CD's presently. Might add turntable later and maybe an amp.
