Thanks Matt
I guess I was looking for a better/seamless front soundstage.....which I may not obtain with any horizontal center.
Many on this forum have reported switching from 150 to the 180 was a huge upgrade,
In my room with my ears I am not seeing much of an upgrade( if any at all),sometimes depending on material and which seat I'm in,the 150 sounds a bit better( more clear)sometimes the 180 trumps the 150 depending on content( more laid back ,not as forward as the 150).........
But in all honesty about 90%( or more) of the content I throw at these( a good 5 hrs yesterday alone) they sound more similar ,than different.
Thanks guys and still would like to hear from others......
