Pardon this if it is OT - I am curious about this. I have only heard a few Dynagroove records, and rather than do laborius research, can someone describe what is going on with them? All I remember about them is that they had a raised ridge around the circumference to keep them from rubbing together on the grooves... What are the issues about the mastering and pressing? Offlist if I am the only one who wonders... <L> Lou Judson � Intuitive Audio 415-883-2689 On Feb 12, 2006, at 4:33 PM, Jeffrey Kane wrote: > RCA was WONDERFUL until the Dynagroove era.
