Great setup! Yeah, thought about bi-amping, but I'd need an active crosser to "do it right". So I'd rather choose a more powerful amp first, one which can handle the 4C. Yes, looking very forward to pull the trigger on one. But not before February / March next year, unfortunately.I've got the Reference 203, 202c and 201s - the first series of them. If you have a multichannel amp, I think you can use it to bi-amp any of the Reference series - I know I can with mine though there is no need with mine as I've got enough power with my 200W ATI 2005. I hope you're able to pick up the 4C, that's a terrific center channel speaker!
Maybe not related to this thread, but anyone used the new AT54xNCs? How do they compare to the ATI 600x? I can see they are much lighter than the 600x and deliver a lot of power.
