The loading of the cartridge controls the mechanical damping and therefore resonance (Mainly R) and the overall frequency response (Combination of R and C) of the stylus and cantelever. BUT theres no reason you cannot apply the R and C loading to a flat gain stage (Use the recommended loading for your cartridge) and apply the RIAA (or other) EQ in software Jeff *Players:* SliMP3,Squeezebox3 x3,Receiver,SqueezeLite-X,PiCorePlayer x3 *Server:* LMS Version: Latest Nightly on Centos 7.5 VM on ESXi 6.5.0U2 on Dell T320 *Plugins:* AutoRescan/BBCiPlayer/PowerSave/PowerSwitchIII/Squeezecloud/Spotty/Player Groups *Remotes:* iPeng9/Orangesqueeze/PC/Jivelite/SqueezeLite-X *Music:* 522GB,1660 albums with 23087 songs by 5204 artists mostly FLACs *Want a webapp ?* See http://forums.slimdevices.com/showthread.php?104305-Webapp-for-LMS ------------------------------------------------------------------------ Jeff07971's Profile: http://forums.slimdevices.com/member.php?userid=49290 View this thread: http://forums.slimdevices.com/showthread.php?t=110295 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/ripping
