We have a Toto Aimes 1-pc toilet in our guest bath room that makes a "cluckety-cluck" sound when flushed. Our plumber said all the Toto one piece 1.28GPF sound like that, and that the two piece 1.28 GPF toilets are quieter for some reason. We're about to remodel out master bath and the designer suggests the Toto Legato 1-pc. Looking at the spec sheets, these two toilets are identical except for the shape of the trip levers. I really like the sleek lines of the one piece model, but that flushing "cluck" isn't worth $1500. The Toto website has a video with the double cyclone flushing in action, but the voice over guy covers up the sound somewhat, and you only hear a couple clicks rather than the deeper sounding clucks.

All the showrooms I've been to don't have working toilets. Does anyone here have a Toto 2-piece 1.28 GPF with a trip lever (not the push buttons) that is quiet?
