I give my amp and phono stage at least 15 to 20 minutes before I play my system. I have a zyx diamond gold and it sounds the same from first touch to the end of session. I recently replaced my benz micro lps which needed at least a side or two to sound its best. Best of Luck
How long before your cartridge warms up?
Wondering if people would share how many sides of a LP must be played before they believe their cartridge has warmed up and is on "full boil" so to speak. My Ortofon MC Anna seems to like about 2 to 2.5 sides of an album (e.g. 33.3 rpm) before it really comes to life. This is something I am just starting to notice as I am fairly new to analog.
