ok here we go,now have the defs fed by the VAC 30/30 sig mk3,the player is direct to the amp and is the opus 21 modded by GNS.the speaker cables are Zu Ibus and interc to the amp is Discovery sig. the Zu guys did put 320 hrs on the speakers but they still sound better with each listen.my room sucks shit so work to be done there,13 by 18 with open beam ceiling at 8 feet.i think i will keep the Zu's as they sound freaking phenomenal so far,with room treatment i can't think what they will do.those boys are up to good things at Zu.to the guys with the def's,what are you runnin' for amps,just curious as i think the little vac is a gem,will a SET do better?? more to come,summer is for outside.
