Cable INteracion Question

I am trying a new set of cables, and when I insert them between the preamp and amp, I hear a ton of noise (sounds like the capacitors charging) in the amp at power up. When I revert back to my old cables I hear no such noise. What could be causing the "noise" in the new cables??

You might want to discuss this problem with someone at SAS, and inquire if the V cable is appropriate for the location in which you are using it. It may be meant for source to preamp applications.

I'm sorry but I'm not that familiar with the SAS cables. Are they shielded (the Sonoran cables are). Try reversing the orientation of the SAS cables and see if that helps.

More info needed. At least:

Brand and model of both old and new cables.
Brand and model of amp and preamp.

I was going to mention the connector(s) too, however I assumed the noise was on both channels which would pretty much (not completely) rule that out.

The pulsating phenomenon sounds to me like digital "hash" (RFI) coming from your CDP (or DAC). Unplug your digital equipment and see if the problem persists. Also, make sure your digital equipment is on a different circuit (if you can) and that it is connected to AC using a shielded power cord.
