How long before your cartridge warms up?

Thanks Effischer, you may be right. I did some more experimentation today and it could be anything from the load on the utility box at the time to other components warming up (bearing in the table).., etc.

I usually have the amp and the phono pre powered up for at least 2 hours before I start any listening.

I agree with all that is being said here except that I don't think 40 minutes is excessive. I did note Mike Fremer at the latest Axpona stating that he finds his cartridge needs about 4 sides before it is at full stride.

I think what I experienced was an abnormal difference in the recording quality of a track on an album which was new to me; my subsequent testing today would indicate that my Anna does not need a wam-up period.

My Graaf amps are another story, the GM200 need about 30 to 45 minutes, the Modena (signature version of the original Graaf GM20) can take up to 2.5 hours to be at its complete best.

I did adjust the VTF already as the warming weather audibly necessitated that change. I believe, that was done about 4 weeks ago.

I find this whole discussion interesting and I have already gleaned some good things to take from the discourse. Thanks all.

So it does appear that is my room is below 75 degrees F my cartridge (MC Anna) requires a side or two to warm up and start delivering on the quality I know it to be capable of.., realized this last night when the sound wasn't so great and I correlated it to my over zealous use of the "cold" button on the thermostat :)
