CEWACK  While this program has promise, it has issues with 10.5.2 (and possibly earlier versions of 10.5) most notably, preference boxes are partially obscured not allowing the user to access any of the settings in those particular boxes. That being said, the default configuration does a pretty good job on cassettes. Haven't tried it as yet on vinyl. I won't buy it until it's ready for prime time (10.5.2)
