MM Phono cartridge

Get a Stanton 681EEE. I have one in my collection.

The Zephyr is getting long in the tooth.  So I was contemplating a change vs a rebuild.  If I were to change, it would be to find a bit "rounder" sound.

@rivinyl I apologize for not responding to your earlier DM as I don't use the DM service on this site (just too much required info/exposure when I'm not an active equipment trader). But would definitely like to pick up that convo on another thread...

As for MM carts in your price range, I've been eyeing the Nagaoka MP-700 and will likely attempt to order one this weekend. MSRP is ~$1400. Here's a review: https://www.hifinews.com/content/nagaoka-mp-700-cartridge

I have the Nagaoka MP500, Stanton 881s, and the Garrot 77 I believe it is. All way under budget, all good. Of the three, the Garrot is the warmest . The 500 has the advantage of stylus switching if you play other speeds. 

I have the Nagaoka MP-500 and love it.  They just came out with the Nagaoka MP-700.  I would get the 700.
