Van den Hul Frog Gold. The only cartridge I've used in my main system since 2005 (re-tipped in the meantime ofc). Before that I tried shedloads of different ones, MM and MC, none of which made much impression. I have an Ortofon MC20 on the turntable in the 'upstairs' system, but I haven't used that for a while.
If memory serves The Frog is Rudolph Huckers favourite cartridge of all time...
Whether that is an endorsement or not........!!!!!
He doesn't use it though. Which, again, may be an endorsement or not. I bought it with trepidation, as it was far more expensive than any other cartridge I'd ever bought, even at the bargain price I got it for, but it's proved its worth over the 15 years or so I've owned it. When I'm even older and more doddery than I am now, I might have to biff the vinyl, but the Frog Gold should see me through till then.
