I can think of several ways in which faster development could lead to better quality. Let's say you have a fixed time to come up with a solution to a problem. If you are able to come up with one candidate and evaluate it in that time, you have to live with what you get. If you do two candidates, you can select the one that is better. Another aspect of quality is "polish". A team that can get a UI in front of QA twice in a development cycle instead of only once will benefit from more fault-finding.
