Both, actually. Most amps with an A/B speaker option just have the A and B terminals wired in parallel. In other words when both A and B are turned on, there is simply a wire connecting the output posts inside the amp case. So the A and B posts are electrically in contact and therefore electrically identical. In a world where wires are perfect conductors there is no difference between bi-wiring a single amp to a speaker, and single wiring that amp to the speaker, because in either case the two speaker terminals are in electrical contact. In the bi-wiring case the path of electrical contact goes down one speaker wire, through the post, and back along the other wire, and in the single wiring case it goes through the shunt you put across the two posts on the back of the speaker. So the only difference is the resistance of the speaker wire compared to that shunt, which (for anything above coathanger quality) is negligible. This is much easier to draw than to explain in words. On the other hand if you really have a different amp driving each speaker cone there can be a more substantive difference. I'm glad the system sounds good - congrats! -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=30074 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
