Ben, I believe the differences between SACD and redbook after modifying my SCD-1 did indeed become less noticeable. The redbook is so good now that it's very close on initial listening. There are differences still. Better and smoother extension with SACD. SACD is more of a musical experience where redbook is more a display of imaging and audiophile terms. The SACD is comparable to the differences in digital to analogue. More natural, less edgy, smoother, more relaxing.
With the modifications to my SCD-1, I do not feel like I'm missing much when playing redbook. In that my library is mostly redbook, I find I'm listening to redbook more often. If the redbook playback was a great step down I'm sure I'd be wanting to upgrade, as it is I've had no feelings of upgrading for three years and during that time I've had many of the "best" digital players in my system.
