All says that speakers of Denon are not good... But avr is, although have not got any demo, thinking about avr and speakers as single unit.As far as spending about 25 to 30k for Onkyo 3400, it can be a future ready option with 3D ready, 1.4a HDMIs and finally a decent sound output. However, if you stretch a bit you will get DENON 1311xp wiith 3D support HTIB around 28k and has a active subwoofer and bigger wooden encased speakers, superior to Onkyo 3400. Check with Croma.
htstore has a combo of denon 1311 + jbl scs140bk... looking at that but could not audition because the store is in B'lore....
