Nagaoka MP-50 exc condition

Nagaoka MP-50 cartridge for sale. Considered one of the best MM cartridges ever built. The cartridge has solid boron cantilever and line contact stylus. The body and stylus is absolutely the same as the top of the line Nagaoka MP-500. which sells for $700.00

I am cutting down my system due to a move to a small residence. Hence I have been selling my gear. My new residence is 1/2 the size of my prior home. I need to sell my large system.

The cartridge is in near mint condition with 25 hours of play time. It had 20 hours on it when I purchased it and I have only put 5 hours of time on it. ( A few LP's)
The cartridge comes in a plastic shipping box. (Note the picture that shows the name Nagaoka is upside down. The cartridge is really lying on it's back, not on the stylus. I rotated the picture so you could see the name.) The headshell in the pictures is not included.

This cartridge is considered a classic. The Line contact nude stylus tracks with superior accuracy. The Vinyl Engine gives 5 stars for its performance. The only MM cartridge I have listened to that is as nice as this cartridge is the Grace F9 which is also considered a classic.

Specifications:
Output: 2.5 mV
Loads: 470 kOhm
Unloads: 3800 Ohms
Tracks: 1.1-1.5 mV
Compliance: 12

The stylus is user replaceable and it uses the present stylus for the MP500 cartridge.
This is an excellent cartridge.
