The ytr732 is one sweet sounding horn. I would characterize it as being a very compact sound compared to the ytr634, not necessarily a brighter tone, but a sweeter one. It is not as dark as the 634, and not as loud, which would make sense, being a smaller bore. The sound is more together than the 634, more surrounding, with less sense of projection. I felt like I was swimming in a warm trumpet sound - in the middle of the sound, whereas with the 634 it's more a feeling of projecting the sound forward. (At this stage I should point out that so far I've been limited to playing the horn in my bedroom, and that I use a Monette B2 mpc.) I'm still getting used to the blow, so overblowing to go loud, but I think it will bark if pushed.

 

I own a YTR-737 and you would be hard pressed to tell the difference between this horn and a B-5. I know I can't. Check out the serial #. If there is an "A" after the number, then it was made here in the states. I was also informed by a former Schilke employee from that era that some of these horns were put together by Schilke employees at the Schilke factory. Granted that these were Yamaha parts after Renold Shilke's design, they were still put together and adjusted by the master craftsmen at the Schilke factory. This fact has long been denied, but in his words, " Hell, man you're playin' a Schilke." IMHO they are some of the highest quality horns on the used market today.
