anbody ever hear of an outfit called dynagroove records?

And then came DynaFlex.

+1 bdp24! RCA's failed attempt to improve the sound by altering the EQ during the process of cutting the master. None of the resulting LPs made from this method sound good! Worthless junk, IMO! The record jackets stated on the fronts "Dynagroove". 

After Dynagroove failed to increase sales, RCA came up with another dubious scheme: Dynaflex. Pressing LPs with HALF (or less) the amount of vinyl! Supposedly to prevent warpage due to shipping! These actually can sound quite decent, as long as they remain without warpage. 

So all you RCA collectors, pass on those horrid Dynagroove LPs and check any Dynaflexs' for warpage!

RCA Dynagroove 1964 Amal and the Night Visitors is as good or better in terms of sound quality as almost any RCA Living Stereo.
