Dale Caliente!

Do they have a version of this without the Minidisk??? The 70 watts and all. It is 70 watts total wattage??? The site is in JP and I don't see this unit on the English site. Is the sound from the two bookshelf speakers decent? Punchy bass is what i'm looking for. I hope it has good crisp highs and mids too. The subwoofer out is great, i'll put it to use. I want to buy this system for mostly Rap music. Does this unit fill a small room with sound well? I'm going to use it for a 10x8 Ft bedroom. I want to be able to hook an MP3 Player to this unit. I'm hoping the L/R inputs on the top left of the rear are RCA inputs. This thing has optical in right? One more thing, does this system have a built in amp? It seems like it, looking at the photo of the back of the unit. I need a mini/mirco system bad. My PC speakers are gone. This looks pretty good. It has a lot of aux input/outputs. Optical in is exactly what I was hoping for. You know too hook up external stuff. If you guys can clear that up for me I might pick this up. BTW, how much in USD, under $500 I right.
