Re: SACD Worth IT?
Of course they're worth it! Multi channel SACD or DVD-A are the best. (those with 2.0 vinyl fetish can't be reasoned with so let's save readers the trouble; I have good vinyl it doesn't compare with SACD or DVD-A)
The Genesis box sets are reason enough to invest IMHO and they are not even the best examples of the format.
Blu Ray DTS MA is even better but it remains to be seen if a catalog will result beyond Neil Young's Archive release. Some producers tend to think so.
