I know very little about what changes when using different DSP's, and would love to hear some opinions on what people like to use.

I personally have always used Yamaha receivers, and have been a big fan of 7CH Stereo or 7CH Enhancer. To me it sounds like this clones the audio in every speaker, and is great for listening to music or watching an event on TV that is not made to be heard in a surround setting.

I don't like most of the effects that other DSPs put off that try to mimic things like "Roxy Theater" or "Chamber". I don't like my sound being processed more than it was intended to be.

Is "straight" just passing audio based on the source?

Would love some opinions and different scenarios. Thanks!

Yes, 7 channel stereo duplicates L/R to the matching pairs of surround speakers. While that's fine for background music at parties, it seems odd to hear voices that belong in the center coming out of all the speakers.

Those other DSPs with names like stadium and jazz hall are useless in my opinion.

Try PLII or DTS Neo:6. They intelligently expand stereo to 5.1. The music modes of those DSPs give the user control over the width and depth of the sound expansion. I use PLII Music for all stereo sources.

I'll occaisionally have fun with some of the sound programs, mostly Cellar Club; but for music I almost always come back to 7 channel stereo. I like the room filling effect. Pure Direct is nice too, but lacks the punch of 7ch stereo, so I usually go back. Also, sometimes I use the sound programs to make up for poor recordings, dead mixed can be livened up a bit.

That's for music, for movies I always stick with Standard.

True -- however, the way my main zone is set up, I am not always facing towards my center speaker. I have a computer set up directly below my SideLeft speaker, facing the direction of SideRight. So even if it was just me and I was using my computer, in that instance I would only hear voice coming from the right side. I know there are other problems with this setup however.

Agreed.

I saw the Neo ones on my new receiver. Meant to check them out. So basically this would be like how PLII takes sound meant for 5.1 and intelligently expands it to 7.1? Except with music? Does it only support 5.1 or is there a Neo 7.1? PLII Music sounds like a good idea too -- that must keep all vocals in the front and expand the L&R channels to the sides and rears?

Thanks!

Haven't tried Pure Direct.. does that mean it only plays what it was recorded in?

Also, does anyone have experience on what "Enhancer" does? My old Yamaha used to say 7CH Music Enhancer, now it just says 7CH Stereo, and Enhancer is another optional altogether.

PLII expands to 5.1. PLIIx expands to 7.1. DTS Neo:6 does both, although the rear expansion is mono fed to both rear speakers while PLIIx does stereo rears. These modes work with all sources. The DSP doesn't know you are listening to a movie or to music.

Pure Direct bypasses all digital processing, including bass management and room correction.

There is no right or wrong with these modes. Use whatever sounds good to you.

Ah I see. Thank you for the very helpful information.

And out of curiosity -- does BIslander stand for Block Islander by chance?

You're the first to comment on it. My favorite by them, followed by The Seventh House, or maybe their newest.
