Vinyl noob needs help with cartridge

What kind of phono stage do you have?

The 2M Black and 2M Bronze are moving magnet carts with a pretty high output, (5mv).

The Zu/Denon 103 is a very low output moving coil (.3mv).

If you have the gain, the Zu/Denon is a wonderful cart. I have one on my Oracle Delphi MKIV and love it.

If you have only a MM stage, the Ortofon 2M Black is great. I have one of those also on a different table. I upgraded from a 2M Bronze and it was a worthwhile investment, although the Bronze was no slouch.

The Audio Technica AT150MLX is another excellent MM cartridge.  

I know that several members really like the newer Audio Technica MC carts, like the AT33 and the OC9/III, but again you need the gain for these.  The Audio Technica ART9 is supposed to be really nice also, but sells for around $1000.

I was a dealer for and have personally owned everything listed above except for the SoundSmith.

While I'm a HUGE Dynavector fan, (probably my favorite cartridge manufacturer), the 10X5 is okay, but not in the same league as the other carts listed.  If you could afford a higher end Dyna, like a 17D3 or above, that would be my choice.

This is strictly my opinion, but I have a massive amount of experience in the turntable/arm/cart arena. Okay, my list, (of the carts you mentioned above) would be in order:

Zu/Denon 103
Audio Technica OC9/III
Audio Technica AT33
Ortofon Bronze
Dynavector 10X5
