When I remodeled my listening room I kept the monoblock amps by the speakers and moved the other gear to a side wall in the back of the room. This made a 7 meter run from the preamp to the amps. I had been using a 3 meter pair of Purist Audio Venustas interconnects. A 7 meter pair of Venustas would have been horribly expensive. So I switched to the Harmonic Technology Cyberlights. Being fiber optic, long distances are not a problem. Before I moved the equipment I and some friends did a listening test between the Venustas and the Cyber Lights. There were small differences in the sound, but no clear preference for one over the other. Long runs of Cyberlight are not that expensive ($2,300 MSRP for a 10 meter pair).
