I have a turntable with a built in preamp option so I can plug it directly into anything as you would an iPod without needing a pre-amp. I wanted to move it down to my basement as part of getting a fancier setup for the living room but wondered what the most basic setup I could use is?

I thought I could just plug it straight into a speaker like the A9 or something but a friend says that the volume is reliant upon the source, even if it's active speakers. Do any of the B&O speaker range (old or new) control the volume at the speaker end of the system? I know I could just get a separate amp and speakers but I really wanted something super simple like a a cable running to a speaker setup on the wall, not a system with loads of buttons and inputs that will likely never get used. The BeoLab 5000s look fantastic for hooking up on the wall actually, is it possible to add some kind of volume knob to the line out cable?
