I got the chance to play two Taylors this past week. They are at Roberto's (RIGHT next to Sam Ash) in Manhattan. Correct me if I'm wrong, but they are one of the few stores in America that have Taylors.
Taylor Chicago Custom 
This horn played much more like a "normal" horn than I imagined. It is not muffled and stuffy like other heavy horns I've played before. It had a nice dark (but not too dark) tone, and EXCELLENT response. My double tongueing had never sounded so clean before. It slots very evenly up to the High E (above high C), and probably slots further, but I was a bit shy at the time and didn't gor for it. It projects well in all registers, with a nice fat tone on the bottom, and gentler in the upper register. It doesn't have a big "bite" up top, but can be pushed either direction (dark or bright). The valves are super fast and very smooth. The finger buttons are titanium, and recess when pushed down. Very nice.
Taylor Pheonix 
This horn played extremely similary to the Chicago, but with a different sound. The one I played was copper. It definitely played to both extremes (dark and bright), and screamed more. I don't know if it was because of the copper, the internal mechanics, or the rectangular bell. It reminds me or a hot rod even more in person than in the pictures. The bell is just like a side mirror (very cool looking horn). For those of you wondering, it empties 'spit' just like an other horn does.
Hope this is of use to any of you. If you have any specific questions, ask away. I know I didn't touch on everything.
