Interconnects - better before preamp or after preamp?

@jumia -

     BAT VK-D5 CDP to TacT RCS 2.2X pre = KS1130 Kimber

     TT to phono pre = Tricon Analog SR

     phono pre to TacT = KS1030 Kimber

     Tact to Cary SLM 100 main amps = Tesla Apex SR*

     Tact to Hafler 9505 sub amp = Gold Eclipse 8 Wireworld

     mains speaker cables = Big Silver Oval  AP

     subwoofer cables = 8TC Kimber

     two runs of 10/3 Romex from mains box/same 20A breaker to room/Hospital Grade outlets

     outlet to Stealth XXX power conditioner  = AC Master Coupler SR*

     outlet to Hafler 9505 = AC Master Coupler SR*

     PCs to all other components from Stealth = ZU Mother

     wall to VPI SDS = stock

     SDS to tt/SAMA = Zu BOK

                        Nothing fancy or expensive.

                                Happy listening!

Every component, including cabling will degrade the signal to some degree. NO component can “improve” the signal and the best we can hope for is that the component will degrade the signal as little as possible, Of course, how much any one component degrades the signal is not an absolute; electrical compatibility with the component that preceded as well that which followed will also be a factor.

                                                 EXACTLY!

                       NO cable can possibly improve your signal.

         The goal is to compromise the signal's integrity as little as possible.

     Think of cables as windows, between your components.     Just a single dirty one, anywhere in your system, will result in a compromised reproduction of your music.
