I have M60ti's, and use to have a VP-150.. I always thought the 150 was undersized... well, in my opinion it is!... I got a 180 when they first came out... it is kind of like going from a 3 cylinder ugo, to a supercharged corvette... there is almost no comparison between the two speakers... The 180 fits in perfect with my M60's... Often times when i had the 150 i would not listen to music in multi-channel mode, due to the 150 being so much smaller than the M60's, hence making the listening environment not ideal. With the VP-180 i listen to music in Multi-channel mode now, the 180 integrates seamlessly between the M60's and has absolutely no problem keeping up with them in sound output, and sound stage...

Like yourself, i had been wanting a larger center channel for Many years... So when the 180 was introduced i did not hesitate to order one immediately.
