Default ucd180 vs ucd400

I am new to this site but not to audio. I am thinking about buying used/building/having somebody build me a UCD180 or UCD400 4 channel amp for bi-amplification. Power is not an issue as I want these to drive my horn speakers. I would like to hear from people with experience with both these amps which amp is sonically superior. Perhaps there is already a link dealing with this issue. Thanks.

I am interested in this as well, I always thought they were similar and would sound the same except for the power levels. If there are sonic differences otherwise I would like to know why, what is different between the two. Was there upgrades in the circuit design or parts that make the UCD400 a bit better in some fashion?
