Basically this is what I am trying to understand. What are the benefits? Better sound? Better connectivity? Upgradability? All in the price point of less than 30K.
suppose u have a basic system like a tv...a tatasky hd...a dvd/BR player with hdmi out...
now u want that u play a hd channel and ur display is on tv and the 5.1 dolby digital sound plays in ur speakers....
u play a original dvd disk in ur dvd player and want ur display in tv and 5.1 sound in ur speakers
just imagine how you will connect ur systems if you dont have a system having multiple hdmi input..and one hdmi output....
u can only enjoy the video thru hdmi into ur tv/pj and still enjoy the 5.1 proper dolby sound..in case only and only if u play a dvd disk in that particuler ht system u are interested now....
but that is not the particuler case we always play...we play hd channel/our laptop/from other player/games with hd sound/...etc etc...
all entry systems from onkyo/denon/hk/yam/pioneer have this feuture but the sony/lg/sammy they dont have.....
this was the connectivity part only.there are many other feutures..if you follow the specs....u will easily understand..
better upgradibility---
definitly...think u buy a blu ray player and play origional br disk with dts-hd sound track....then...or u buy a game plyer/or u want to hook it up with ur hdmi pc/laptop
better sound----yes of course---onkyo/denons/yam/pioneer are the dedicated av reciever makers certified by dolby lab...
if you still think u will do without hdmi...then u can go for a non hdmi model of denon/onkyo/yam...at a very very cheap rate(discontinued model if lucky..u can get)..with 6 different channels analouge in....then connect them from dvd player analouge 6 channels out...and use composite for video...
at 30k range u blindly buy denon 1312...onkyo 3500/3400..or yam 296..acording to ur ears.all they are good systems..sound diffrently to diiferent ears..
edit--I just checked logitech z906.it nowhere stands with a dedicated av reviever and speaker package...also it is inferior than market avilable sony/pana ht packages.......if u want to play from pc only(pink,green and blue jack) and intend for pc speakers..then u can buy 5.1 creative/intex speskers at a much much cheaper rate.........why it is priced at above 31k
......where denon 1312 is also around 30k..32k..
