Hello all! I have recently had the chance to extensively play test a yamaha 8335 xeno trumpet, since my university has several available for students. I was play testing against my two horns, a Bach 72 and a Bach 37, as well as a classmate's older yamaha 6335HS II. First of all, the build quality of the yamaha was outstanding. The horn really feels great in your hands. the valves are nice and smooth, and the slides work well, even after several years of use by university students. The horn was very easy to play in tune, and the intonation was very good. The xeno, by all technical standards, plays extraordinarily well. However, I did not like the fundamental tone of the horn. I felt that i had to work very hard to achieve my particular sound on the xeno. Compared to all four horns, I felt as though I had to work much harder to produce the tone i am accustomed to on the xeno, and never really felt as though i got the warmth and depth to my sound that I usually do with my main player Bach. After several head to head comparisons, the best way i can describe it is its as if the xeno has a similar sound as my Bach 37, but without any warmth or depth, and sounded dull to me, as well as the classmates i had listen to my play tests. Surprising to me, the older 6335HSII outplayed the xeno, having very similar playing characteristics (the 6335 felt like it needed more air to fill up than the 8335) and a much more warm and rich sound, and I thought this horn was the clear winner of these play tests. Ultimately, ill be sticking with my Bachs, even though in terms of intonation, note accuracy, and ease of playing in tune, the xeno is a tad bit better than my 37 and a solid bit better than the 72. I feel more satisfied with my sound on the other horns to justify a slight improvement the other characteristics, so Ill keeping the Bach as my everyday player. As a final thought, im honestly not sure i would have noticed the difference in tone with the yamaha xeno had I not been playing on two relatively good Bachs to compare and had been issued this horn as a substitute from a student/intermediate horn or lesser quality pro horn, I would probably be overjoyed with the xeno. Anyone else have any thoughts/comments/similar or different comparisons with these horns?
