wow...those are all good stuff...try them on...some gems there

most Marantz AVrs are equipped with pre-outs for all channels...search for them first...

or if you see any AVRs of your liking, see the back panel and check the pre-outs...coz some brand models don't really have these..make sure u get those with the newer processors if you can

with 5k sure you can...but don't expect hi-end stuff...here's my take:

720p projector - rm3.5k (optoma hd65 is nice!)

marantz sr series - get one with pre-outs...and hopefully with HDMI ...should be around rm1.5k..

the remaining - get yourself a descent HD media player (HDPRO, WDTV - rm400+) or a decent blu ray player (philips bdp3008 - rm500)

so voila - u're in for 5k

with an AVR like the Marantz with pre-outs - since u already have multichannel power amps . just hook them to all the pre-outs of your AVR...and let the AVR bcome your process...

could still get an independent processor but this one normally will cost a lot more...since entry level brands don't really have cheap-ish processors

but if you wanna go 1080p and play all the latest HD audio stuff...don't think rm5k would do it...

720p is good enough actually - depending on the size of the screen u wanna have - oh btw - screen you can DIY or buy those normal matte white for rm200+ or so...can find them easily nowadays

if you have extra dough...for now just get a decent sub - no need those expensive ones...upgrade when you have more $$

just my .02 sen...

i have this setup actually...got my old Marantz sr5300 hooked up to a power amp and let the power amp drive my floorstanding Mission 733i - and let the Marantz drive my centre and rear ... happy with the sound

so yeah...good luck!
