Cartridge recommendation for classical listening

I've been a classical music listener for many years.  I use an AT MC cartridge on a VPI TT into a 3 stage all tube phono pre.  Here is my $.02 in no particular order.

I wouldn't buy a moving magnate cartridge without a replaceable stylus.  There are too many good ones out there.

What you want for classical music (or any other kind) is just the best cartridge for your needs.   The cartridge doesn't know what kind of music it's playing.

There are very good cartridges with varying compliances.  Best to match it to your tonearm's effective mass.

For a MM cartridge, easily replaceable styli and good value I would look at the Ortofon line. 

The very best cartridges for any music are MC cartridges.  In the long term, you might want to consider either a phono pre-preamp or a step up transformer that would allow you to use a MC cartridge with your CJ.  Or you might even go for a separate phono preamp and bypass the phono section of the CJ, 

the 1812 Cannon shot is the same as a Bonham kick drum ! well, sort of. 

but as an owner of Grado and a Nakagoka - they are both sweet but do sound different on a Basis Rega OEM300 arm. The Grado has the edge in midrange magic and lushness, the NAK is more incisive and daynamic - particularly in the low end and lower mid bass.

IF in NY Nick At Audio Connection is awesome TT setup guy.

None of these guys have ever run a Rega cart in a Rega arm . They do
not know what they are talking  about .

The idea that you have to match the brand of cartridge to the brand of arm is ridiculous.  It is the kind of nonsense hype broadcast by Rega which sells a lot of arms and would like to sell a lot of cartridges, some of which are simply re-badged and repriced from other manufacturers.  Over at AA where lots of systems are listed, most owners of Rega TTs who list their cartridges are not using Rega cartridges.  Now, some of Rega's MM cartridges may be terrific.  I wouldn't really know as I haven't considered MM cartridges for many years.  But I have friends who have found success with Ortofons.
