When it comes to the center channel you have more flexibility. It's not prone to the issues that the 80s have. The 80s are A LOT of speaker (not to mention they play in 4 ohms which not all receivers are capable of). You're getting more in the 150s vs the 100s. Here you'll have a similar comparison as between the 60s and the 80s. More detail, more volume capacity. But here's a case of turning it down (if needed) for balance will do well. The center channel is THE most important speaker for movies. 70-80% of the sound (dialogue) will come from it. So...I'd go with the 150 personally. But I believe them to both be excellent units. Many people who have the 60s have gone with the VP150 as their center channel, so it's a fine match.
