oh yea i was woundering if on the megaworks does it have a digital input? and if it does do i need a new cable to use that feature? but im not really sure about recommending u guys getting this speaker system, i still have this system downstairs and it sucked, i compared it to the jbl 2 speaker system (no sub) from compaq, vs the z640s, i personally thought jbl did a better job on their 2 speaker system then logitech did with the z640s, but no i got the megaworks of couse im using these, the logitechs sound just sounds flat, not saying logitech is a bad brand but their low end speakers do kidna suck, but high end im not so sure about since i never owned their high end ones, oh yea and if ppl wanna get a good system theres alawys the refurb klipsch on ecost for 120, promedia is a excellent thx certified 400 watt speaker system, hum lets do some math here u get aronud 80 watts on the logitech for 47$ and u get 400 watts for 120$, lol just dosent add up the wattage for $$, lol j/k there
