Hi Kevin,
Congrats on your new amp.
I have used a variety of speaker cables over the years with my Thiels and either Krell or Classe’ amplifiers. Maestro’s were good. The Crescendos were better. SR Tesla Precision Reference, even better. Replaced them recently with Cerious Technologies Graphene Extreme, much better still (and inexpensive compared to SR). FWIW.
