After using a Courtois 400 Prestige Symphony plated for quite a few years I wanted to keep his round money. I came across the series of XO at Jupiter makes a lot of noise for some time.
The image of Jupiter for me it was "good instrument quality / price ratio, but for beginners".
The pro class is another story.
A lot of very good musicians play on. So I tested the XO Gold.
- The branches of mouths silver / zinc long / short zinc.
- Perfect for a classic with its very round.
- It's not really a fault, but the trombone is very heavy because of the silver.
- Reserved for the classic.
Very happy with my purchase. But to see the long term.
