Let's face it, most speakers below £500 have internal wires that probably only cost 50p and that you could buy from the local hardware shop. Not ideal really, considering you spend much much more on the equipment and speaker cable to have the internal wires be the rate determining step. So, I re-wired my speakers internally with QED Silver Anniversary wire. This cost me £7.50. I, in fact, only soldered in the wires as add ons (in parallel) to the existing wire, but it's made one hell off a difference! The treble is smoother, the whole soundstage more cohesive. The Bass is stunning. I auditioned a pair of Quad 21L floorstanders and my Tannoys have better depth and balance, but MORE bass that's better controlled (btw my speakers are 12yo Tannoy M15's that are standmounts not floorstanders). I'm well chuffed that my entry level Tannoys outshine a pair of Quads (that cost 3 times more)!!!! Does anyone else have similar good (or bad) experience with re-wiring their speakers? Do you think I should remove the old wire all together and just leave the QED wire in place?
