5 cartridges - Cello, vdH, Benz, Zu, Hana - what stays and what goes?

Cello Chorale. By Isamu Ikeda;  

No, it's not Ikeda, this cartridge designed by Takeda-San

 Haruo Takeda, the former Audio-Technica employee who went on to design and build phono cartridges for Krell, Mark Levinson, and Cello, and who even lent his talents to Koetsu in that company's early days. Approximately 30 years ago, Takeda-san began making his own artisanal phono cartridges, which he sold under the trade name Miyabi—a word that can be traced to a Heian emperor's court, and describes a subtle, refined, "toned-down" aesthetic infused with sparkle and grace.  

+1 chakster! That Cello mc cartridge is a real gem!

Learn how to mount a cartridge for yourself and keep them all until you have had ample time to evaluate each one in your particular system.  At that point, you may want to sell one or two, but the decision will be wholly yours. Or maybe instead of ditching a cartridge or two, you ought to consider mounting a second tonearm, if your turntable permits.
