I forgot....I DO have the distances set on the 47ai. By the way, my manual says the the distances do NOT apply to SACD playback. Is the 45a the same? This implies we STILL don't have complete bass management in a "universal" player yet. Also, the bass output from the LFE is week. I have to turn the level to max, and the main channels to minimun to get them to match. At first I thought is was a problem with the 47ai's tone generator. But then I saw a post on the HTF with the same problem. I checked the levels with the Chesky DVD-A disc, and yep the LFE channel output is weak.
