I do have to think on this some more. I will configure the player for all large + sub and connect the sub. I am not sure how to test the presence of LFE. Can this be done audibly?
Yes, a slab floor would be reflective, even though there is carpet, etc. But of course wood flooring will transmit bass more effectively (for better or worse).
Well, overall I am quite pleased with the performance, but want to learn more.
I would also like to experiment with 2 channels, as that is how I enjoy personal or more critical listening of CDs.
If just listening casually, when there's company, etc., I usually leave it in the PLII-M mode.
I sincerely appreciate the comments and suggsstions.
