I've been toying around with an op-amp based head amp that I've put together and hooked it up to my Oppo player. I measured 16 mV DC offset at full volume from the analog audio outputs...yow...and followed it upstream to the Oppo player. On one channel I have 12.5 mV DC and on the other, 12.8 mV DC. Doesn't this seem awfully high for a modern disc player???
Anyone else with an Oppo have the same amount of offset?

Are you using "Mixed L and R" ?
I normally don't use Analogue Out from mine, as after sound deadening material combined with replacement of the SMPS bridge rectifier diodes with BYV26C, and a 100nF 630V across the main electro , it sounds noticeably better via SPDIF. In fact, even Video via HDMI to a friend's 1280 projector was then also markedly improved. (glossier looking picture)
My friend then did the same with his 981HD.
I just tried mine, and although it started off at several mV, it dropped to
0mV after several seconds, indicating that it is via electrolytic capacitors.
