Two big sounds got-ta face off

ok,the question of the day is,is there a real winner between these two titan speakers:Zu Definition---- Vandersteen 5a. to all that have heard both,what did you think???? or are they both simply real good with different flavors???? this is a question that i gotta ask????
I would bet the Vandy 5A would blow away the ZU, but wrong or not I would love to find out.

i did buy the Zu's,and am presently feeding them with the little VAC 30/30.signal coming fron an Opus 21 modded buy Steve @ GNS.i really like the Definitions,make no mistake there.they truly sing.but,have a real itch with the 5A's i gotta house taste-test.will A-B with same gear.

this will be fun for sure,i'm thinkim' a real gloves off scrap! [maybe not?].on the flip side,this may not be on the fair side as one speaker is nearly twice the cost.i think it's a flavor thing.
