the MX 966 package have a lot of option . I love the reality that it enable I to eliminate my old large bulky speaker -lrb- enough space for two more chair -rrb- , along with my AM\/FM Tuner and Equalizer .  with all the connector in the back , it tie in my dvd changer , CD changer , Cassette Deck , turn Table , satellite system , and VCR while allow I switch to any component from one source .  while watch dvd I be impress with the sound from the `` optical '' audio hook-up . it rock !  with 5 satelite speaker of 100 watt each , I never need to go above # 25 on the volume knob , which go to 50 -lrb- my kid tell I I be hard of hearing -rrb- . the `` powered sub-woofer '' have 100 watt also and be impressive on the low bass noise . it will rattle you window if so desire !  over all , this be a great update to any sound system for this kind of cash !
