I'm looking to upgrade my centre channel. I'm currently using an old Mirage one, and it's the only part of my system that isn't timbre matched - the rest are M60 V1's in the front and QS4 V1's for the surrounds. Am looking to get either the VP150 V4 or VP180 V4, and am leaving more towards the latter, but I worry that it might be overkill when the fronts are M60's. Has anyone had a chance to hear how they perform in this kind of setup? Do they sound overpowering compared to the M60's? And should I be concerned about a V4 speaker not being well-matched to a system of V1's?
