I'm looking to upgrade sound card (running with a Fortissimo III), and it's basically between the Revo and A2 ZS. I forgot where I heard this from, but the Revo has some sort of problem with the Line-In? I have a Leadtek Winfast 2000 Tuner card, so if that's the case, I think I'm going for the A2 ZS. Can anyone confirm this?
