I always thought the BH was over hyped
you may want to try Audioquest type 4 or Discovery 123
these have been known to be giant killers
otherwise the AZ is a good choice though may be slightly warm (not neutral)
I use Woods $6 extension cord (White Lightning) with amazing results but no longer available I am afraid
I have also heard Cardas sound terrible
system synergy is the key
good luck
