Koetsu cartridges. They must be something special.

This just in: platinum is not magnetic. The platinum in cartridge magnets is probably an alloy of Pt and Co, somewhat akin to Alnico (aluminum/nickel/cobalt) where both Co and Ni are magnetic.

I was aware of Koetsu in 1978 through The Audio Critic, who tested one. It was the world's first cartridge to sell for - gasp! - $1000. Peter Aczel said it was the best he'd ever heard. Don't give me that bullsh*t about inflation making that $1K Koetsu worth $4K in today's dollars. There is so little material in any phono cartridge to justify the outrageous prices asked today!

@lewm : Guitar pickups and strings determine the sound of an electric guitar. The body material/shape have no affect. The magnet material and number of coil windings is where the "magic" resides.

i recently got an Analog Relax cartridge—manufacturer reportedly used to work for Koetsu. Its midrange is even more immediate than my Blue Lace. Bass is pronounced too. Only problem is it’s a prototype and doesn’t have the excellent tracking noted in reviews of the EX1000.
