Phantom Center sound better than a center speaker?


I was messing around with my HT setup last night. I have B&W 603S2's in the front with a B&W ASW600 sub. I picked up some Axiom speakers for surrounds and have a VP50 as a center surround speaker for my 6.1 setup. I currently do not have a center but will be getting a B&W LCR600.

Some of my rears have not come in yet so I figured I would break in my rear center surround by using it as my center channel front for a while. I knew the sound would be compressed since the VP-50 has small dual 4.5" mid's while the B&W's have dual 6.5" mid/mid-bass. However I was not prepared to have the sound literally shrink away. I watched TV (analog inputs) and DVD's for grins and came to the easy conclusion that the center I have is not up to the task of keeping up with my front towers.

However, here is my question:

Does a phantom center sound better than actually having a dedicated center speaker in HT? The LCR600 comes with dual 6.5" midbass speakers and a matching tweet but will it have the output to fill out the soundstage? My fronts are only 12' apart and the room floorspace is smallish 16x18 but there is alot of airspace due to vaulted ceilings and no wall between the kitchen and the family room.

Any help is appreciated.

Sorry for the long winded post.

sean...For large musical ensembles, a symphony orchestra or the like, lack of a center speaker is not significant. However, where there is a solo performer, vocal or instrumental, or movie dialogue, and that performer is isolated in the center channel (per usual practice) I find a center channel speaker to be essential. Somehow, having two Joan Baezs singing in opposite corners of the room, and asking my brain to pretend she is only one is distracting.
Hiroshima - See my $.02 on this subject under the "Question re: HT furniture setup" thread. I vote "yes" for using a center-channel speaker for HT! Incidentally, the "LCR" model designation for that speaker stands for "Left-Center-Right". You can either use 3 of them up front or mix one in with your 603's. They are voiced to blend very well with any of the other models in the 600 series B&W's..
Thanks for all the repsonses. I think I have gathered that some like the dedicated center and others don't but it seems to depend on how many people are watching the movie. Since my audience varies, I will try to audition the center before I pick it up and see what sounds best.

Thanks again all.
El: the fact that you have your speakers spread out in opposite corners tells me that you probably do need a center to fill in the gap. Like i said, the closer that the speakers are together, the less likely you are to need a center channel. Sean

sean...True, my speakers are further apart than I would put them if I didn't have that center speaker. (The geometry of the room dictates wide spacing, and hence the center channel). However, even with "normal" spacing, I find the "phantom" center to be unsatisfactory unless the listener location is fixed and optimal.
