I used the original plugs with different wires on my system. I did not find out whether the plugs can be purchased - and I wanted to use my already installed (good) speaker wires:
- pull the metal plugs out of the plastic ends (use pliers on both the cable and the plastic end to prevent cutting your fingers with the metal plugs)
- cut the original wire and solder yours to the metal plugs (keep it small - the plastic ends are quite narrow). alternatively you could leave a few blank millimeters of the original wire to ease soldering (wire to wire), but then you will have to isolate the blank wires
- re-insert the metal plugs into the plastic ends (preserve polarity).
not the funniest job, but it can be done.
I dont know whether this voids your warranty - which you might need (see firmware thread...)
I just bought this system and wanted to switch the gauge wires to 14 gauge instead of the 18 (20? 22?) gauge that come with it. I was horribly disappointed to see that there are plastic ends that plug into the receiver.
Are these plugs universal? Can I buy them somewhere else? Is there a way to take them off and put on my own wires?
p.s. if you're wondering why i'm switching them, it is to not lose as much strength on longer distances, I have done this on other samsung HTIB and there is a CONSIDERABLE difference...this is beside the point...thank you!
