I play a goldbrass-bell Virtuoso (son's hand-me-down).
The straight-out horn position is cumbersome, especially for standing, but it's better ergo to ease the fingering strain on my right forearm. Overall, I'd prefer a more "traditional" position, given the option, but it's not a big deal.
In blind sound-tests, we preferred my son's Sterling tone over the E3 sterling bell and all the Yamahas, which seemed to have too much of that Yamaha "pure" silvery, brittle sound.
The one vexing "hmm, maybe I should shop for a different horn" issue: I have to keep the Sterling super clean or the 2nd valve sticks badly (probably unique to my particular sample).
My other complaints:
concert BNat an octave above the staff seats poorly and only plays on 2nd valve. D above it won't seat clean for me - those might be me, not the horn, but neither my Willson 2975 nor 2900 acted this way. High concert C sits well using 1&3.
I prefer a horn that slots a bit tighter, but that's totally personal player preference.
Concert G in the staff is best tuned on 3rd valve, but that's common and not a deal-breaker.
Biggest playing beef is that the scale's not as even as on my son's Prestige, but again, that might be unique to my sample, and it doesn't affect the final result - it's just not as fun for me, as the player.
