From what I've read regarding Vandersteens is that to get the full potential out of them they must be bi-wired. No jumpers. No internal bi-wire cables. Two runs of cables from the amplifier. That increases cost. Doesn't say you have to do it but from what I'm told the difference in sound is significant
They also require a certain size spade to fit so if you already have a set of speaker cables you either must have them reterminated, use adaptors or bare wire.
I'm considering auditioning the Treo CT but having to take into consideration the above is definitely a barrier to me doing so
