    I'd guess setting the Oppo to max output from min output gives an increase in dynamic range aka 'bit depth' - higher signal to noise ratio, hence more audible detail and so forth.

    But he said he's using the volume so it's not max output. Could be full volume was overloading the pre and it sounds better this way. Have heard about that with a few DACs.

    We don't know what volume the Oppo was set to before though. If it was set at full output previously and clipping the pre-amp, which as you say can happen, it would have sounded pretty poor.

    Assuming it doesn't clip the pre-amp the optimal thing to do is have the Oppo at full output and adjust volume on the pre-amp. That way you know you are getting the full dynamic range. But then that means no remote control of volume.

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

    You've got it Lawrence. Croft Pre fixed at 7 O'Clock, and Oppo CD volume anywhere between 15 and 75, which rocked the Kasbah

    To clarify, I didn't know about this function before yesterday so wasn't aware but the Oppo output volume was fixed at 100%.
    Don't get me wrong, it was sounding fine before. I just wanted to be able to control volume by remote. I wasn't chasing improvement.
