bi wire works best for biamp
my old technics sada 10 had bi amps- when biwired-biamped sounded quite good only problem was technics sells junk.(owned 6 months used 3 weeks rest of time in the shop-then after 3 months they send a replacment unit-there cheapest unit. i wouldnt accept it .they finaly offered to buy the unit back so in 8 more weeks ill have my money agian.
i biwired my speakers to my yamaha i dont know if it made a difference or not-you could tell the differece when i did it with the technics biamp
