Help with advice for high end speaker cables for my system!

Hello I could use some advice with speaker cable choices.  I am using a Marantz AV-7704 preamp, 2 Krell  KAV250a amps, and a Krell KAV 250/A3 amp.   The 3 amps are running to a pair of Martin Logan Request floor standing speakers, a Martin Logan Cinema center channel, and a pair of Martin Logan in ceiling surround speakers.  2 of the amps are bridged, one each dedicated to a Martin Logan stereo speaker, and the Krell 3 channel amp is running the center and rear surrounds. I listen to about 50% stereo music and 50% home theater.   I could really use some help and advice with stereo speaker cables for the Martin Logan stereo speakers.  All the high end shops in my area seem to have closed, so the ability to demo different cables is apparently not an option.  I am considering Audioquest Oak cables, but really open to suggestions, especially if you have used similar components with good results.  Thank you!!
