what integrated and speakers?

Hi all im new here, got out of audio 5 yrs ago for many diff reasons i wont go into. here is my dilemma: i have not a lot of money, and need new system. a large 'chain store' has a deal with no interest financing for 3 yrs. they have the music hall mambo for 1300.00. i listened with klipsch rb5-11 and sounded good. they also have gallo, i would get the neucleus with passive sub. how does NADc320BEE compare with mambo? i will mainly be listening with a ipod mini hooked up with apples connector. i have no cd player just x box and ps2, could hook either one up to mambo by optical, but couldnt hook to NAD since no analog out on either xbox or ps2. eventually i might get a turntable also. i know neither amp has phone section i can add one later. i have heard great things about the 320BEE but not a lot about the mambo. does anyone have experience with either? if i get the mambo/klipsch or mambo/gallo i can finance with no money up front. if i get the nad at a diff erent store i will have to pay 400 cash, and get the speakers thru the chain store. i have owned a lot of tube integrateds in the past, i want tighter bass but not at the expense of being 'bright'. Also, the mambo has no pre out so how do i hook up the passive sub if i were to get the gallo passive? They say the mambo is class A but is it true class A? or is it push pull? single ended? Basically, i need your help. Also i have heard obviously about the epos for around 300 bucks, but would have to pay cash for those also. thanks for any advice you may have.
