Can I connect a speaker system (with its own power source) to my TV using the headphone socket or is there a chance I could break one or both of them? I've checked the manual and it doesn't say (it's a Sharp Aquos LC19D1EBK).
Several years on from this post, I am also using a headphone jack to an rca out splitter. Sound appears OK to me, loads of bass, etc. I tried going through an external Dac from the TV optic output but found no discernible difference in sound quality. No doubt if I spent a few £Ks I might but the headphone out to my Musical Fidelity amp and forward to a pair of B & W CM8s seems fine to me.
