David Soyer, who was about a dozen years older than his colleagues, retired in 2001, and his place was taken by Peter Wiley, Soyer's former student. The transition was symbolized in a Carnegie Hall concert that year, in which the Guarneri performed the Beethoven Quartet in B-flat major, op. 130, with Soyer playing cello, followed by the String Quintet in C by Schubert, with Soyer and Wiley taking the two cello parts. The incorporation of Wiley as cellist was a smooth one: "I don't feel like the new guy," he remarked. "I was a fan of the quartet since I was 11 years old…It was a very natural transition for me." Dalley added "It was actually very good for us when Peter came in, even though the quartet field was new to him…I think I learned more from Peter than he learned from us. He had a lot of good ideas that were brand new to us."
