Center Channel


I currently have a Monitor Audio Gold C350 center channel and have been contemplating getting the Monitor Audio PLC350. Unfortunately I can't compare the two. Has anyone compared the two to each other?  Are there significant differences between center channels that justifies paying 5K for a center channel?

Audiobunker,
Very interesting comments. Everyone says "the center should match the fronts." I have PL500s and have been thinking about the PLC350, but I'm honestly trying to stop changing equipment when I don't "hear" a reason to. Since I don't have a dealer that has the PLC350, I thought I would ask the question. Thanks for taking the time to respond.

The issue is not comparing one center speaker to another, it's as you say,
"the center should match the fronts."

With stereo only the image is created by 2 identical speakers. A different L&R would not create much of an image. Now with a center channel between the L&R, the image is created between the left to the center, then the center to the right. The perfect scenario is to use 3 identical speakers across the front, however that can only be done in specific situations. The next best thing is a timbre matched center to the L&R.

Take a look here especially the last line,

Here's another good read about matching front and rear, but the principle applies to matching the center. Looking at that picture, think about the airplane actually starting in the left front speaker moving across the front, then through the room from the right front to the left rear. The only way to create that sound perfectly is to use all identical speakers throughout the room. Again, that can only be done in certain situations and timbre matched speakers will definitely be better than mismatched.

Your current center is a much better match than a different brand would be, but the timbre matched center should be better than that.

Thanks. I read both articles including the last line, "With movies being recorded and mixed in the studio with 5 (6 or 7) identical speakers, shouldn't we be listening to our movies at home with 5 (6 or 7) identical speakers?"
In my situation it's unrealistic to have five Monitor Audio PL500 IIs. I'm thinking about the transition from left to center and center to right when viewing movies and I'm happy with my current setup. I've spent a lot of money(at least to me) on my 2-channel and just can't seem to justify spending almost 6k on the PLC350 II center to match my fronts. Thanks for your input.
