Mga bro,
my av1600 has controls for bass, treble, center, and surround volume, and of course main, but none for the sub out, but I don't think that's neccessary if you're gonna use an active sub. Line level outs usually don't have volume controls naman e.
Pareng Maki,
I haven't auditioned out Konzert amps, and they seem decent, but does your DVD player have a built in Dolby prologic processor? Kasi if it doesn't, you might want the Sakura na lang 'coz I havent seen any Konzert amps na may prologic, and we all know you need it for 2ch sources.
