Koetsu Are Not Universally Loved.....
Just like anything analog, there are those who appreciate Koetsu--and those who chose an alternate path to their analog nirvana.
Cartridges all have their unique presentation of the music. There is probably more variation in this category than anything else in audio.
At one time in the 90's the Rosewood was considered to be one of the finest cartridges in the world, but not the most accurate. It had a midrange to die for, and that made up for any other minor deficiencies it had. Such as lush bottom end.
As the years have gone by, there have been many great cartridges built. The list of companies is numerous, and I know I have missed many of them.
But a sampling is ZYX, VandenHul, Shelter, Miyabi, Transfiguration,Dynavector, Ortofon(top end carts),Cardas, Benz Micro, and the list goes on and on and on.
The only way you can know if a Koetsu is worth it to you, is to listen to one.
At one time I owned a Koetsu Black. It was a nice cartridge, but I preferred the speed and dynamics of a Dynavector 17D2 to it. Cartridges are a personal thing, its best to give them a listen to and make up your own mind. Guess its kind of like dating, and finding that person you plan to marry.
