oppo's volume control

Let me add that, if you connect the Oppo directly to power amps and you use the Oppo's settings for individual distance/delay settings, you must install the newest beta firmware. Earlier versions have a bug which will actually implement the inverse of what you want (e.g., a longer distance when you set it for a shorter one) and this will have a significant impact on stability and imaging.

From what I've read from the main Oppo experts on AVSForums is that the Oppo always sounds better with a pre-amp.

"Always" is a dangerous qualification or lack thereof. For example, any preamp vs direct into any power amp via any cables of any length?

The "official" word has been that none of the 10X series are recommended for use as a preamp although Oppo recognizes that many will want to do it.

FWIW, I have yet to hear any clicks or pops from any of the Oppos but I never use them without a preamp.
