Steve - I took an interest in the London Decca cartridge 5 years ago. But it was at the same time as my Quad 57 subwoofer project in Room 2, which took priority. That Sub project went really well. Last few years I have plodding through my library in music lover mode with my "Freedom Fighter" cartridge - a Benz Micro MC3 retipped by Peter of SS. Top one in this picture.

It's a great cartridge for playing many records as it makes all of them sound good with minimal VTA changes needed.
So, with being stuck inside during winter, I am starting to do more research on the London again; with the objective of coming up with formed opinion based on theory. These "theory" opinions - imo (8^) are worth 10% of real experience opinions. They are good enough opinions though, I think, theory opinions, for spotting a good deal when it comes about. I never buy anything unless it's a good deal, and the Canadian dollar has pretty much killed buying audio items except for maintenance items, like my recently re-tubed RM9 Music Reference amp.
