pare this is just my suggestion pero try to up your budget a bit higher to maybe 6k or 7k and try to get a unit being sold here sa pinoy. I just recently sold my AVR na denon 1602 for around that price to one of our newbie friends here. and it was in excellent condition pa. over 2 years old lang. so kung stereo, you should be able to find a lot of good pre owned items.
that way, you get a unit with better specs and wont be tempted to upgrade very quickly. then maybe just try to find other ways to cut back like temporarily using your existing dvd player or being very choosy with the cds buy.
i have learned in this hobby that very often, when i pay just a little more, i get so much in exchange. it is almost always worth it.
on the other hand, when i scrimp too much, i find myself re selling items i had just newly bought since the unit does not quite satisfy.
i guess patience is a virtue. especially with audio.
