I'm using CDex. The CD-ROM settings allow you to set whatever read sector length you choose. Default is 26. The manual says a higher readsector length will significantly reduce WAV extraction time - if you have a decent CD-ROM you can set it to 400. I have set it to 20000 successfully but got the fastest times from around 8000 to 10000. Is there any reason I wouldn't want to do this? It seems like there is much less opportunity for jitter.
