To conduct the tests I first made a set of jumpers using 12 gauge speaker wire soldered to gold plated banana plugs.
Test 1: For the first tests, I left the speaker cables attached and only used the jumpers. For test one, I jumpered the negative side only. Listening to my favorite test track, Hotel California on the Eagles Hell Freezes Over CD, I had my wife alternate having the jumper in and listening without it. I could hear no difference. Test 2: This time we alternated jumping both sides. We went back and forth three or four times and I heard no difference. Test 3: Now we disconnected one half of the bi-wire speaker cable and left the jumper in. Again, lots of listening and no difference. Test 4: I the other thread it was suggested that there might be a difference in SPL. During the test 3 listening I thought I might have heard a reduction in volume so I played a 1khz test tone and measure SPL with wires configured for both bi-wire and jumpered. The power of persuasion is pretty strong as both tests measured exactly 92db. So thats it. There may be electrical differences with bi-wired speaker cables but on my system at least, I could not hear them. -Ben -- Ben Diss 'SB3' (http://www.slimdevices.com/pi_squeezebox.html) -> 'Lavry DA10' (http://www.lavryengineering.com/productspage_da_10.html) -> 'BAT VK-31SE' (http://www.balanced.com/products/line/Vk-31SE/index.html) -> 'Halo A21' (http://www.parasound.com/halo/a21.php) -> 'B&W 803D' (http://www.bwspeakers.com/index.cfm/fuseaction/products.models/label/Model%20803D) ------------------------------------------------------------------------ Ben Diss's Profile: http://forums.slimdevices.com/member.php?userid=4289 View this thread: http://forums.slimdevices.com/showthread.php?t=34318 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
