Yes, something you do not want to know about as it will destroy your system. Elizabeth is leading you into audio hell.
Does anyone know what I saw ?
One time I went to an audio store to try out a new preamp. To check out the back panel jack quality, I took a look behind the large audio rack the pre was in. In addition to the standard RCA cables running into the preamp, I also noticed what looked like speaker lamp chord cable spliced to the RCA cables with a "T" type connection. If I recall, this was on the output side of the preamp. Why would speaker cables be hooked to a preamp output?
