I have purchased a second hand Technics SL-23A which is a very nice unit. So far, I prefer it over my Audio Technica LP120USB model, which I find a bit overrated.
The SL-23A came equipped with a Panasonic 2700-II cartridge and unknown stylus. I know there's nothing fancy there so would maybe be looking to upgrade at some point.
My preamp stage is the Art DJPRE II going into put my computer and my amp is a Marantz 2225. I have a switch that will allow me to use the phono on my Marantz if I don't want to go through the computer.
I am looking for a cartridge/stylus (max $250) suitable mostly for heavy metal, hard rock, and death metal that isn't going to exacerbate sibilance and has as low IGD as possible and has good bass and midrange response and not too treble-y.
Firstly, is the Panasonic cartridge worth keeping? If so, what stylus should I be looking at to fit it?
If the Panasonic isn't worth keeping then what would be a good cartridge combo for my SL-23A for my criteria above?
Edit : Thinking about an Ortofon 2M Blue Plug N Play.
Thanks in advance.
