    Evening,
    I have a 5.1 system in my lounge (Kef 3005's running on a Denon 3803) but am setting up a new system in my old dining room.
    I am considering a 7.1 system but will I really gain much from it - the room is not massive.
    Thoughts appreciated.

    As this is the subwoofer forum, I can categorically state that the sub is a major part of a 7.1 system.

    As someone who had a 3802 (3803 with a few less whistles), unless you have a lot of room behind the seating position, the extra speakers add little and that which they do, is at the expense of the other five.

    they do however come in handy for late night low volume listening in 7 channel stereo.

    You need to use a proper DSP, not 7 channel stereo. Logic 7/Music Logic etc....DVD's aren't 7.1, they're upto 5.1 so you need to expand it.

    Bob, I see what he's saying.

    It's about really low volumes and the spread that 7 speakers can give, that keeps the dialogue intelligable. I'm not sure that 5 speakers would do any worse and as a purist, obviously wouldn't entertain the idea myself, but for the less discerning, it may have some merit.

    Yours, obviously taking the ****,

    Russell

    PS. 7 channel "stereo" allows me to knock the volume back by 6-7dB which is a lot if you're in the room above.

    Just use dynamic compression/range setting.

    That's what I'm saying. I used to use the 7 channel stereo setting before I had the SMS-1 with it's 'Night Mode' for the sub.

    If you want the levels between loudest and quietest to be closer you have to use dynamic compression. 5.1 v 7.1 has no relevence here.

    I run a 7.1 system in a small room, if I use 5.1 or 7.1 it sounds the same from front array. Never use dynamic compression, it's off.

    :thumbsup:My NAd T-163 also supports"night mode". You can select the speakers and I have to say that 7.1 in night mode, with only the rear surround and sub sounds really nice! It makes for a good mood, if you get my drift....
    Oh well, it all comes down to one thing really. Would you be happy with 5.1, knowing there is 7.1? Hehe! That is the question....
    Cheers, Chris
    :lesson:PS. Btw it seems that 7.1 is not enough anymore! I have seen amps with 7.1+2"effects" channels!!!! LOL! Where does this end???:lease:

    Russell's first post is important, rears need room to breathe and it sounds like this may be tricky in your room? I started with 5 and jumped to 7 whlist I could still buy M&K :). Sure you can play with more sexy decoding algorithms on the amp but other than filling the gap between my LS and RS (which does give us more flexible seating arrangements -the LS/LR are 5m apart) I'm not sure the rears add a great deal.

    The only DVD we have that actually mixes a dedicated rear is Pearl Harbour, I'm sure there are others but the vast majority are 5.1, so it comes down to how well the amp's software works. My boys mutter about not getting true 7.1 on the PS3 games (I have to use optical audio) but as far as I am concerned there is way too much racket in the HC as it is :(

    Now I think about it, my 3806 (and my old 3802) both had a 'Night' setting in amongst all the other DSP options, which is much like badbob's DRC. I'll try using it tonight.

    night mode is only usable with DD input. (3806)
    you cant use it on DTS or analogue.
    i did notice that the night mode was activated last night when i was watching law and order svu on hallmark so that must have been broadcast in DD stereo.
    my wifes son must have left it on.

    you notice my sig Russell?

    i personally prefer 6.1 becauase you have the lef and right surrounds and a centre you can place right behind you, in a 7.1 setup it all seems to be coming from the sides in a small room and i dont know about this myself, but wouldnt adding more speakers take more amp power and thus take away from the other speakers slightly, and ive not seen a dvd with 7.1 on it yet, if youve got decent speakers im sure they will project sound into those extra areas anyway, maybe 7.1 is only good with sattelite speakers to fill the room more , i had a mirage centre turned upside down near the ceiling as a 6.1 rear and that worked really well with my aegis evo surrounds, i think 7. only works well if you can have you chair a distance away from the rear speakers

    also it takes more room, more wires, more speakers, more playing around with the amp and the remote, more positioning, and whats wrong with 5.1 anyway, its surround sound, spend more on 5 speakers than on 7

    Kinda agree re 6 or 7. But note the rears should be close together, around 3 ft and not "further back sides". Often the rears are playing the same tune but are useful to fill a hole between the sides if you have a large room and if you can sit well forward of the rears. Otherwise forget it.

    You think sats struggle to fill a room?

    I recently switched from 5.1 to 7.1 and despite having the rears basically above my listening position (recessed in a shelf) they do make an improvement to rear effects, especially in 7.1 soundtracks, although I admit even on HD Discs these are few and far between.

    However when I consider the cost of the extra speakers and the amp upgrade I needed to give me the extra channels... it probably was my least impressive performance/cost upgrade :) ...and as we are discussing this in the subwoofer forum, I can share with you my greatest ever upgrade was my sub ;)
