do you want performance and all in one convenice?
eg, if you want perfomance as well as flexibilty, go for a proper av amplifier, some thing like yamaha rx-363 or sony STR-DG520 (if you stretch more try a marantz or denon or onkyo) and a set of tannoys efx-5.1, you will find that the perfomance is unrivaled ( scale and realism) as well as faithful reproduction of movie soundtracks (and music) and you will endless options of connectivity and upgrade options, ps you will scare the neighbours as well, but these equipment take up space.
should you be able to stretch more and don't mind bigger speaker( even better peformance) get a really decent set up with some like mission m3i speaker set up.
Mission - M3i
or something more compact - kef kht series
KEF - Innovators in Sound - SURROUND SOUND SYSTEMS - home theatre - home theatre KHT1005.2
if you want convenice, but don't mind compromising performance, get an all in one, but beware all in one can break down ( i deal with a lot of insurance claims for these items ) as well as limited connectivity and no upgrade.
ps, the built in dvd player within a all in one system will be poor compare to your current dvd recorder ( assuming your using hdmi upscaling)
HK$4,000 is a starting point.
it's not just my opinion, Uk's magazine what hifi will say the same.
ps, broadway and fortress is a poor choice for any decent audio product, as you will need to demo the equipment in a proper demo room, just like you will test drive a car to see the characteristic suit you.
ps. also, spend 10-15% on cables, as you would not drink champange in a polystyrene cup.
