Interconnects and speaker cables

Hello, I have Klipsch Cornwall IV speakers and am purchasing AirTight tube monoblocks and an AirTight preamplifier.  I was hoping someone could steer me to the best interconnects and speaker cables for my system.  I mostly listen to vinyl and to that end, 55 -67 jazz, early blues, acoustic guitar, bluegrass and at times crooners.   Thank you very much for your recommendations.
