Matt,

I'm not so sure there is a "correct" placement standard. If there is, the mixing engineers and producers are not in agreement. I think the Chesky Records' format reassigns the classical 5.1 center and subwoofer channels to left side/front and right side/front, respectively. By side/front I mean 55 deg from center. The rears/surrounds are supposed to be at angles between 135 and 145 deg. Still, other "specs" reassign the 5.1 subwoofer channel as a center height speaker where the speaker is over the center channel, up near the ceiling. I don't remember where that one came from. For the recordings I've sampled, all the channels are full range.

In many, if not most, cases, we're playing these discs on a system that does duty as a home theater system. The producers of these discs apparently think that we're going to have a dedicated system for multichannel music listening and all the speakers are full range and that we're going to go through the trouble of moving the speakers around based upon where the producers expect them to go.

I don't have full range speakers and the 950's bass management on the 6 Channel direct works perfectly for me. I don't have any of the Chesky discs but in order for them to work properly on my system, I'd have to disconnect the center and subwoofer inputs from my DVD player and listen to them as 4.0 with the bass redirected to the sub.

there is a standard for mixing and playback of multichannel music discs. sacd recommends it. chesky has good points in his argument, but his suggestions are only that and not a standard. the ITU standard is found here, if anyone is interested.
http://timefordvd.com/ref/itu.shtml

this is the set up i chose to use. i had to install a small powered sub (hidden), connected to the center channel to make it "large". the other 4 speakers are identical, and i have the room to conform to this standard. of course, the rear surrounds are moot in sacd playback. i have a new sub that eliminates double bass.

i've hardly watched a movie since receiving my 950 and completing this set up. IT SOUNDS TOO GOOD FOR WORDS. as i've posted before, if there is a better sounding preamp for this format, i haven't heard it. (sorry for using every opportunity to sing the 950's praises, but i really am THAT impressed with it).

this set up, i've found, is also very good for HT. the thx specs don't work as well, to me, and i find the itu standard more flexible and a must for multichannel music.

BTW, I think that the negative patman may be the mod on another forum who previously had problems with the 950 due to user error?
Then again... haven't we all?

Bosso,

Thanks for the info. Does the ITU discuss full range vs. sat/sub anywhere? While the placement info is helpful, I'm still at a loss to explain why the producers and engineers put high frequency stuff in the subwoofer channel if this is the standard they are following.

Regardless of my affiliation with any forum or not, I'm simply pointing issues that new users need to be aware of.

We're dealing with semantics of what "processing" is when it comes to the bass management of 6-channel input. If you have bass management for these inputs, then there is "processing" whether it be analog or digital to filter out and funnel the low end bass information to the LFE output from the 950. If you think "processing" is only reserved for "digital" filtering, you may have a point. I prefer to see "processing" as altering the input signal on its output.

Plus, my issue with the 6-channel input has shown that there is a problem going from 2-channel bypass to the 6-channel input mode on the 950.

If you are in 2-channel bypass mode, and then choose 6-channel input mode, you will only get the 2 front channels plus the LFE channel. My expectations when I hit the 6-channel input button on the remote is to get all 6 channels to be active when playing a DVD-A or SACD.

This is a bug, not just a misunderstanding on my behalf. It's a bug I can live with, but it exists nonetheless.

My Sony processor (and probably others) do it in a way I consider the best: they use a 6 pole relay to do a 'hard bypass' of the preamp, except for the volume control and output stages.

I have to agree on this one - if you can't do it right, leave it alone. The current state of the 6 channel input is pretty lame IMO. Fortunately Merc found a slick workaround for it.

Here's to relays!
