Mono Cartridge Zyx Airy 3 or Mayajima Zero

I have heard the ZYX in another guy's system.  It sounded excellent.  IMO, you cannot go wrong with either choice.  Having said that, I have pretty much decided to buy a Zero or Premium Be Mono, for little more than half the cost of the Zero.

Don, I, for one, also do advocate using the mono mode where it's available.  However, many if not most "modern" preamplifiers do not provide such a switch.  In that case, one either has to know how to create a mono signal from a stereo one, electronically, or to buy a mono cartridge.  Further, if the mono mode switch is available, I think there may be something to be gained even in that case by using a mono cartridge.  However, if one does not wish to spend the money, a mono switch will certainly be a big improvement over listening to mono LPs in stereo mode with a stereo cartridge.  I guess that's my opinion, too. I happen to have two vintage preamplifiers that provide mono switching; that's how I found out what one is missing if one doesn't listen to mono LPs in mono, no matter how one goes about it.  This is getting monotonous.
