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

@kennyc 

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

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.

+1 for a better MC

Why?  Cartridges ware out eventually. You are already committed to buying one or retipping the one you currently have, so start there!

FYI - I am very happy with my Hanna ML, which is on your short-list (my system is posted).

Good luck with your decision.
