As far as the LP12 goes(which I own), there is no question in my mind that the newest, maxed-out one has a much more silent background than the AC motor ones. I'm unsure if the tune(Linn's basis for audio equipment judging, which actually means when/if your body starts to move to the music, that's the equipment/or, for me, the volume at which you should play your music. They claim, and I agree with, this results in long-term satisfaction with your music playing.) is any better(especially because the price is so high to get this). Of course, it's actually a hope of mine that I can max out my AC version, and be able to live with that, or win the lotto, and upgrade to the DC mod.
