I switched over about two years ago and will never go back. I suggest you get things set up and have a listen both with the VP150 and using a phantom center (tell your receiver you don‘t have a center channel hooked up and it will play the center equally through the mains). Though not exactly like using a M80 center using a phantom center with your M80 mains will simulate what the change from the VP150 will sound like at least at the sweet spot. You may find the difference isn’t worth it for you. You could also try it with your current setup but I’ve found room characteristics play a big role in how much difference the center speaker makes.

If you do decide to make the switch this might work for you:
