I agree DACs will not sound the same, but I wonder if I'm splitting hairs at the price point of the gear I'm talking about? The Oppo does, however, make a point of mentioning that the analog stereo output uses a different DAC chip than the multi channel output DAC via your pick of digitals (optical, coax, HDMI) This is what prompted me to come up with a solution to using the analog stereo output of the Oppo and still get low end info to my sub without using the bass management of the AVR, keeping the signal analog from the source. This is what I'm trying to figure out.
