i have bi-wireable speakers and decided to get away from the stock brass jumper plates. i emailed alphacore with a question about how many jumpers were included in their $20 set. i never received a response and then proceded to buy 2 sets...i only needed 1.
alphacore's audio sales dept. seems to be made up of people who don't have much of an understading of audio playback. and they seem to be overly sensitive when u question them about it. that said, i do like their speaker wire.
