Looking for IC and speaker cable suggestion

My bug finally moves to cables. I have not upgraded my cables for over 5 yrs. I am using a pair of Audioquest Vipper between Oppo 105 and C-J 17LS2. The speaker cables between ARC VT100 and B&W 805s are hefty Monster M series (can't remember the number) that I bought over 10 yrs ago. All other cables are cheap less than $20. I am looking for upgrade to maximize the potential of my gears. Here is my list of components:

2 channel system: Table:VPI Aries I, Phono stage: Conrad Johnson Premier 15, Preamp: Conrad Johnson Premier 17LSII, Power amp: ARC VT100 MKI, Speaker: B&W 805S

HT: Source: Oppo 105, processor: Krell S-1000, Amp: Krell Showcase 7, Speaker: B&W 105S (F,C,R)

Thank you.
