I got the SDA 2B's from here:
Link was still good as of 10/17/06.
They sound very good but didn't come with the interconnect cable. Yesterday I was able to get a cable, locally (pin/blade) and holy-cow this really sucks the enjoyment out of the music.
The amp I was using is a vintage Pioneer A-717 (Reference Stereo Amplifier) rated at 140 watts with a 4 Ohm load. It's supposed to be a common ground amp that can drive low current loads; been happy with amp until I installed this cable.
At any volume level you wish, the sound from the speakers will shutter every 3 or 4 seconds and at the same time you can hear (inside the amp) a clicking sound.
Remove the cable and the sound returns to normal and the amp stops the clicking sound.
My partner in crime used a digital Ohms meter and found both pin and blade has connectivity but that's all we know.
I did hook up a Kenwood KA-8006; it's supposed to be able to drive a 4 Ohm load and got similar action as the Pioneer. Any ideas?
Edit: My partner did a little more work with the Kenwood: the 8006 has been sitting for a while and I guess we were hearing scratchy controls and such. The Kenwood and the cable are actually happy together!
The Pioneer is/may not be common ground? What can I do..is there anything I can do with Pioneer?
