    Audio cable topologies used for SE interconnect cables

    How many times stuff just don't sound good we call it bad synergy lol
    there are many reasons why and this can be just one of them.
    A simple iso can solve this. Does anyone know other ways or have stories to tell.

    Re: Audio cable topologies used for SE interconnect cables

    That’s very interesting, didn’t realize about the RCA differences vs amps used. I’m curious now about what mine are and what I should be using with them.

    Thanks!

    Re: Audio cable topologies used for SE interconnect cables

    I always knew of this due to my Electronic background but to know what preamp and or amps use it is key. Mark Levenson does it's why I posted it. I must use there cables or a in line iso transformer to maintain the sysnergy
    even my no 33 amps say it on the back of the amps. Same with speaker outputs of them.
    I feelnwe need a list of who uses this.
    And lastly this. Of all the high end cable makers does anyone make them. Does any one even know it exists lol.

    Re: Audio cable topologies used for SE interconnect cables

    In the youtube at about 3:30 minutes in, he neglects to point out that the signal is also on the shield. In an unbalanced interconnect, the center conductor is the SEND and the shield is the RETURN. Also he only covered radiated noise, he never got to the other big problem, Common Impedance Coupling Noise currents.

    The engineering paper is about a sensing and switching circuit for manufactured products. More of a problem in portable units than in hi-fi systems.

    Yes, those are three nice engineering papers on circuit design.
    Not too much fun for the average hi-fi audiophile.

    +1

    A shield, connected at both ends, conducts a current which contains both the (-) audio signal and any EM/RF interference. This is one reason many have employed the topology of a twisted-pair conductor core inside a shield which is connected to the ground only at one end of the cable. Here, the shield does not conduct current and is, therefore, not part of the signal path... but, still drains EMI/RFI to ground at the connected end.

    Note: Have been a reader of this forum for a little while now. Thought it was time to join and add my 2-cents on an issue where there can be many approaches.
