So I just purchased a tube amp...The Glow One Amp. Now what I am curious about is what gauges and brands of speaker wire are best with a tube amp, and how they affect the sound quality. I currently use "12 gauge Challenger 2 Ultra High Resolution OFHC Copper" wire with my solid state amps and love it. The speakers I will be using are either Klipsch RB-61's or a pair of homemade bookshelfs. The homemade bookshelfs use a first order crossover and I know the impendence curve of them. So my ultimate question is... I need your recommendations on gauge and so on ! I would rather use something easily accessable and not expensive ! Opinions please !
