This is part of the design of these speakers. There will be no problems. Paul S. Barton(PSB) is one of THE best speaker designers. He covers all his bases. He would not provide the ability to bi - wire if there was any possibility for problems. I have used PSB Goldi with Carver Lightstar amps(electronically the same as the Sunfire), and have to say it is a very good match. This amp being capable of providing the significant current to make these speakers come alive. With lesser powered amps, this speaker just doesn't give its best.
