It is advisable to locate high impedance amplifiers as close as possible to the signal source. But sometimes connecting lines cannot be avoided. Coaxially shielded cables with good insulation are recommended. Polyethelene or virgin (not re-constituted) Teflon is best for critical applications. In addition to potential insulation problems, even short cable
