Oppo BDP-105 Volume Control?

I suggest you review the web site named "Unofficial OPPO BDP-103 Frequently Asked Questions". See:

http://watershade.net/wmcclain/BDP-103-faq.html

It contains some very useful infuriation about the Oppo 105. For example, see sections named Are there any hidden features?, Is the player a Digital Media Rederer? and What are the recommended settings for the OPPO BDP-103?

I found it very useful.

The 105 works fine as a preamp. I have mine hooked up via XLR directly to a pair of W4S Mamp monoblocks. How well it sounds in this configuration will in part depend on the impendence match between the 105 and your amp. And yes per Albertporter's comments, please be careful with the default volume setting as the are at 100. I forgot about that after the last firmware update and nearly fried my speakers. Its beyond me why the default is not 25 or less.

How is the sound with the oppo direct to amps?

I have a bop-105 that I purchased (very lightly) used.
It sounds great. It's volume up control maxes out at 89.
Is it supposed to go to 100? Is there a setting somewhere that is causing it to go to 89 and not fully to 100?
