An oboe player would tell you there are more than three oboe sounds. There are recognizable differences between American, English, Viennese and French which is similar to the Belgian. And this does not include many possible variations found with historical intruments. Like what Handel's Fireworks Music was originally scored for - the English oboe descended from the medieval Schalmey which was a loud, coarse sound more like a bagpipe chanter than a modern oboe. It was called a "war-like instrument." Rather different from today's delicate, refined sound.
I agree with Nick on the VSL oboe which has a beautiful tone. Though there are now vibrato samples, the first release was non-vibrato, which many people immediately and wrongly equate with bad tone.
