Where's the next weak link in my analog chain?

@displayname - nice rig, shows careful choices.

As you’ve discovered, better cables would help.  Consider the new Shunyata Theta line - high performance/price - TAS 2025 Product if the Year.

It would take considerable funds to upgrade turntable + arm.  Maybe next best move is try another cartridge- can always use on next turntable.

Your phono preamp is a strong link- good enough for end game unless you want to explore a tube phono.

Good luck and happy spinning!

Funny you should say that. I was strongly considering selling the 20/20 to get a Chinook SE while they are on clearance. I haven’t even heard one before, but the curiosity almost got the best of me. 

While I can’t agree that cables are a major key to audio happiness, I do agree they make a difference, and a highly colored cable like Cardas GC is likely to take you in a direction you don’t want to go based on your responses. Also I think cable performance is to a large degree hinged to the particular nature of the output and input stages that are being linked. Hence it’s not a good idea to take advice from another audiophile unless you know his system components.

"I was strongly considering selling the 20/20 to get a Chinook SE while they are on clearance."

Your table/SS phonostage is solid.

A tube phonostage could be a more profound change than what been suggested.

Naturally, YMMV.

None of those wiring items will objectively change the sound so the obvious choice is the cartridge.
