How Do I Choose A Phono Preamp

Basically you have normal phono and amp and transimpedance phono amps.

If you are sticking with LOMC then a transimpedance phono amp like a Sutherland “lil Loco might” be an option.

Then you have amps that allow loading to happen easier, and ones with multiple phono inputs.

Moon 310(?) is an example of the ones with easy loading changes.

… and there are a 100 more choices.

My first choice for phono stages is Audio Research… I think a used ARC PH8 is a real sweet spot. You will get the most out of your turntable and your next. I have owned many (slowly upgrading each 5 or ten years) over the last 35 years. Compared to many others… they are world class and very worth it. 

Also Conrad Johnson or VAC or Cary. Each brings a great strength of musicality as well as details and great finesse.

Presto is a newer company

Here's a few, Ear 834p, tavish design Adagio, Musical fidelity mx vynl, pro-ject tube box ds2...

The Gold Note PH-10 is one of the more versatile units at a reasonable price and it sounds amazing

How do I shop for a phono preamp? I’m ok new, or used. Any suggestions as to what specific amps to look at?

I can only help with the “how I did it”.

Features:
- Single or multiple inputs
- Ease of loading
- Maximum gain

Topology:
- Voltage
- Transimpedance

Other:
- Colour (Black, Silver)
- Brands you choose to get or avoid
- Tube or SS

Once you run all the models through a “sluice box” or requirements, then you take what is left as remaining… and try and get a listen to them.

Or you get what sounds good, and then get the cartridge that will work with it.

Since you already have a good cartridge, you have an easier time than with that also an unbounded trade space.
