It's been a while since I listened to the PCS but here's what I remember. You might get a little more detail with the PCS compared to the 1.6, and possibly gain some placement options, but I don't think overall it will be a significant step up from the 1.6. I think the 2.4 would be a step up in sound, but only if you have lots of space. They seem to like quite a bit of space behind and to the sides of them, plus you have to sit at least 8 feet away from them.
so if placement is your main concern the PCS is probably your best bet. That's my two cents.
