Has anyone compared trivista to kw integrated

There have been other people to ask this, but I ahve yet to here anyone who actually compared them. B Anyone who has heard both. By the way what sick compulsion drives me to want to replace a component tha t I love? I mean its not like I can say that I hear any deficiencies with trivista. I don't do this with anything else(car, house, watch, wife) But with audio you always wonder.
