If you own a SACD and/or DVD-A player, and use the 5.1 channel analog outputs, I would appreciate if you might take a minute and comment on your experience with the output of the .1 (LFE channel) when balancing your player.
Some of you perhaps have noted the threads related to LFE channels levels on the Pioneer DV45A and the 47Ai players. That thread can be found here:

Specifically, the .1 channel level, when balanced with test tones is significantly below that of the main channels, such that some users are unable to dial in the bass level properly. In cases where there is enough gain on the 5.1 inputs or sub amp to get the LFE to match the mains, the system may then be imbalanced with regard to other formats (Pro Logic or Stereo decoded by the Pre/Pro or receiver).,
There have been other posts here and elsewhere that mentioned other players (Sony and Denon come to mind) that have the same issue. My purpose with this post is to try to get a handle on which players exhibit this behavior, and which do not.
If you have such a player, please post the model and whether or not the LFE output was below that of the main channels when balanced with Avia, Video Essentials, or other set-up discs.
Given that other players from other vendors have this issue leads me to think that this is "the way it is", although I have yet to here any kind of explanation as to why there should be a difference.
Lastly, to really know if the problem exists would require that the analog outputs of the player be measured with a voltmeter. This is very easy to do (assuming you have a voltmeter!), and will remove the rest of the system from the equation.
Even if you can not take such measurements, I would still be interested in your experience.
Thanks!
Brian
