I can't believe you put up with that for 15 years, you must really love the Quantum. By the way, what kind of tires and pressure do you use? If I am able to cure the noise and decide to keep the bike, am considering moving to 25c tires from my standard 23.
1. I like stiff. Mostly I climb and the Quantum Pro is a great climbing bike... also descends with great confidence. Never felt harsh on long rides though, including one double century.
2. There was really only one road where the buzzing got annoying, it's a rural road and very coarse pavement; only about a mile long, no biggie but other people commented on the buzzing to me. I'm not sure it was the brake cable - that seems to be kind of suspended in the middle of the top tube, I think it was the shift cables... much closer to the inside wall of the downtube.
3. I ride Vittoria Open Corsa, 23mm, 95-105 psig, sweet like sewups.
This is my regular ride:
