Once more, I must agree with prof.
I had several speakers before ending up with a pair of 3.5s and then 2.7s.
I use BlueJeans Cables for my speakers, made from AWG 10 Belden stock, with superb terminal connections - - spades and banana plugs. I've never been unhappy with using BlueJeans cables, both for the speakers and for interconnects. As a plus, saving money on esoteric cables has permitted me to upgrade my electronics and acquire additional CDs for my collection. (Disclaimer: I do NOT have deep pockets, and disposable income has to be allocated to items that will make very clear and unmistakeable significant improvements in my listening environment.
I love to listen to my music, from start to finish, and not be on the edge of my seat, listening for someone in the second violins to miss a beat.
Just my thoughts, after having spent more time with this wonderful hobby than most. My points of reference by which I judge my system are the Vienna Philharmonic in the Great hall of the Musikverein playing Beethoven, Brahms, Mahler and Strauss, plus the Orchestra and Chorus of the La Scala in operas by Puccini and Verdi. Over a period of twenty years, I've been fortunate to hear (and see) symphonic performances and operas in these venues.
