Dear @billpete : Yes, about the 4000D3 was me and if it’s in good operation condition you will be satisfied with.
In thje other side it’s not that I don’t like the FR1 but that the 7Fz and latest way different cartridge bodies are better and even the 4000D3 with a good match tonearm could be superior.
As you I owned 150+ cartridges ( vintage and today ), so I have a ladder gradation for overall quality performance to make comparisons and the FR1 it’s not at the top.
Along those each one of us have our special MUSIC/Audio targets and priorities to listen to.
Any one of you that has interest of top vintage LOMC cartridge try to find out ( very rare ) the Empire MC5 and if you found out any one of you will be surprised of its very high quality performance: it's addictive and unique .
R.
